How to grow potted Aglaia odorata (mock lime) and what to watch out for: it needs plenty of light
Aglaia odorata is a highly ornamental flower, and it can be seen in many gardens across our country; growing it at home can also beautify the indoor environment. So how do you grow potted Aglaia odorata? What are the cultivation methods and precautions for Aglaia odorata? Let's take a look below.
I. How to grow potted Aglaia odorata / it needs plenty of light
If you want to know how to grow potted Aglaia odorata, you first need to know its growth habits. This plant is quite light-loving, so during cultivation it needs to be kept in sufficient light. Beyond that, there are many other things to pay attention to as well. Details are covered below in the cultivation methods and precautions for Aglaia odorata, so let's read on.
II. Cultivation methods and precautions for Aglaia odorata
1. Soil requirements
When growing Aglaia odorata, the first step is choosing the soil. Just as building a house requires laying a good foundation first, choosing the soil is a very important part. For the soil, we can choose a relatively loose sandy soil; this kind of soil has good drainage and is better able to help Aglaia odorata absorb nutrients.
2. Fertilizer requirements
Among the cultivation methods and precautions for Aglaia odorata, fertilizer is a very important nutrient and is indispensable for Aglaia odorata, because if you want the plant to grow luxuriantly, the nutrients in the soil alone are far from enough. For fertilizer, we can choose cake fertilizer, but before fertilizing, note that it should first be diluted with water so that Aglaia odorata can absorb it better.
3. Temperature control
Aglaia odorata likes a warm environment and has little resistance to cold weather, so when growing it the temperature must not be too low. It is best to keep the temperature between 18-25°C, which is more favorable for its growth.
4. Watering requirements
Watering is an indispensable step when growing flowers, and Aglaia odorata is no exception, but how much to water still requires some care. Aglaia odorata likes a warm, humid environment, so during cultivation the soil should be kept moist; generally watering once every 2-3 days is enough, but remember not to let water accumulate, otherwise root rot can easily occur.
5. Light requirements
Among the cultivation methods and precautions for Aglaia odorata, light is indispensable; only with sufficient light can Aglaia odorata grow vigorously. However, in summer when the sunlight is too intense, shading is still needed, otherwise it can easily scorch Aglaia odorata and cause its leaves to turn yellow. Everyone must pay close attention to this point.
6. Pest and disease control
During the process of growing Aglaia odorata, if the methods are wrong, various pests and diseases can easily appear. When such situations occur, we need to promptly find the cause and deal with it in a targeted way. For specific methods, you can refer to the article on pest and disease control for Aglaia odorata, which contains detailed symptoms and control methods for various pests and diseases, so I won't introduce too much here.
Potted cultivation methods and precautions for Aglaia odorata
Aglaia odorata is an evergreen shrub or small tree belonging to the genus Aglaia in the Meliaceae family, with aliases including zhulan, mizailan, shulan, yuzailan and so on. Aglaia odorata is native to China's Fujian, Guangdong, Guangxi, Yunnan and other provinces, and is also distributed in Southeast Asia. It is a common fragrant ornamental plant, and now the editor of Qiannong Network will take a look at the cultivation methods of Aglaia odorata together with everyone!
Growth habits of Aglaia odorata
Aglaia odorata likes a warm, humid and sunny environment, is not cold-tolerant, and is slightly shade-tolerant. A loose, fertile, slightly acidic soil is best, and the winter temperature should not be lower than 10℃.
1. Aglaia odorata likes warmth, sun and fertilizer. The suitable growth temperature is 20℃~25℃. Under normal circumstances, with sufficient sunlight and relatively high temperature (about 30℃), the flowers it produces have a strong fragrance. If in summer it is placed in a shady spot and at the same time given a large amount of nitrogen fertilizer, this is one of the main reasons that Aglaia odorata does not bloom or blooms sparsely with a faint fragrance. Therefore, during its growth and development period, Aglaia odorata needs to be kept outdoors in a sunny spot for care, and attention should be paid to appropriately applying more liquid fertilizer containing more phosphorus. It is best to apply fully decomposed alum fertilizer water made by soaking crushed bone meal, fish bones, chicken bones, etc., and often supplement with chemical fertilizers containing more phosphorus or fermented rice washing water, etc. All of these help with flower bud formation, and result in more blooms, golden-yellow color and a fresh, delicate fragrance.
2. Aglaia odorata likes moisture, and watering should be moderate during the growth period. If watered too much, it easily leads to root rot and yellow, withered, falling leaves; if watered too much during the flowering period, it easily causes flowers and buds to drop; if watered too little, it will cause dry leaf edges and withered buds. Therefore, in summer when the temperature is high, besides watering 1-2 times a day, you should also often spray and wash the branches and leaves with clean water and sprinkle water on the ground where it is placed to increase air humidity. At the same time, fertilizing should also be appropriate. Since Aglaia odorata blooms many times within a year, after each bloom it should promptly be given 2-3 applications of fully decomposed, thin liquid fertilizer, so that it can bloom continuously with a rich fragrance. Aglaia odorata likes acidic soil, so for potting it is best to use a culture soil based mainly on leaf mold. During the vigorous growth period, spraying once a week with 0.2% ferrous sulfate solution will result in green leaves and abundant flowers.
Propagation techniques for Aglaia odorata
Aglaia odorata is commonly propagated by cuttings and air layering.
1. Cuttings include hardwood cuttings and softwood cuttings. The former uses old branches from the previous year as cuttings and is carried out from April to May; the latter uses semi-lignified branches of the current year and is carried out from June to August. The standard for collecting soft branches as cuttings is that the leaves at the branch tip are thick in texture, green in color, and the axillary buds are plump. The cuttings are about 10 cm long, retaining 2-3 leaves at the upper end, with all other leaves removed to reduce water evaporation and nutrient consumption, and the cut surface is trimmed flat. The cutting medium can be river sand, expanded perlite, peat, vermiculite, etc. When inserting the cuttings, you can first use a bamboo chopstick to poke holes in the cutting medium, with a spacing of about 5 cm, then insert the cuttings into the holes to a depth of about 1/3 of the cutting. After inserting, press the soil firm with your fingers so that the soil and cuttings are closely combined, and water thoroughly. Set up a shade frame to maintain a ventilated, humid environment. The speed of cutting rooting is greatly related to the temperature of the cutting medium: with a high bottom temperature, rooting is fast. When the bottom temperature is 30℃~32℃, rooting can occur 40 days after insertion; at 25℃~28℃, it takes 50-60 days to root. But with a high bottom temperature, leaves evaporate quickly and the cuttings' metabolism is in an active state; at this time, if the humidity is low, it easily causes the cuttings to drop leaves, and once the cuttings drop leaves, there is no hope of survival. So high temperature must also be accompanied by high humidity, usually maintaining a relative humidity of above 85%. Before cutting, soak the base of the cuttings in 20ppm~25ppm indolebutyric acid for 12-24 hours, or in 50ppm indoleacetic acid for 15 hours, to promote rooting.
2. Air layering can be done from May to September, but the best time is during the plum rain weather in June, when the survival rate of layering is high and rooting is fast. Generally, Aglaia odorata layered in early June can successively root after 40 days. The specific method is: choose a robust, one-year-old lignified branch with a stem thickness of 0.5 mm. Make a ring bark cut 20 cm from the branching point, with a ring width of about 0.5 cm and a depth reaching the xylem, then apply moss or wet soil to the girdled part, and wrap it with plastic film, keeping the moss etc. always moist. After rooting, cut it off from the mother plant, first hardening it off in a shady place, then potting and planting it. Using this method gives a high survival rate, and the resulting plants bloom relatively quickly.
Cultivation management of Aglaia odorata
Although Aglaia odorata has fairly strong shade tolerance, it is not tolerant of long-term shade, especially when potted Aglaia odorata is in full bloom; it cannot be kept indoors for a long time. When it is flowering, it can be moved outdoors after 4 p.m. and moved indoors before 9 a.m., so that it receives sunlight and accumulates nutrients for producing new branches and new flower spikes. When moving it indoors in winter, it should also be allowed to receive as much light as possible.
Although Aglaia odorata is not strict about soil requirements, a sandy loam rich in humus, fertile and slightly acidic is preferable. When preparing the potting soil, use 2 parts peat soil plus 1 part sand, or choose 2 parts fertile garden soil and 2 parts compost soil plus 1 part sand, mixed together.
After the seedlings are potted, when they grow to 20 cm~25 cm tall, they can be pinched back to encourage side branches and form a crown early, while also controlling plant height and increasing flower quantity.
When potting Aglaia odorata, ensure good drainage, and water according to whether the climate is dry or wet; you must both keep the potting soil moist and avoid excessive water for a long time. Maintaining relatively high air humidity is beneficial to the growth of Aglaia odorata. In dry weather and during the vigorous growth period, it is best to spray water on the leaves 1-2 times a day.
Aglaia odorata has dense branches and leaves, and during the growth period it continuously produces new branches and forms flower spikes, so it needs sufficient fertilizer. If fertility is insufficient, flower quantity will noticeably decline. For this reason, after growth begins in spring, fertilizer should be applied promptly. Fully decomposed cake fertilizer or sesame paste residue water is good for topdressing. Aglaia odorata cannot tolerate concentrated fertilizer, so fertilization should follow the principle of applying thin fertilizer frequently, especially when starting topdressing in spring, when concentrated fertilizer should be avoided. Topdressing should be applied once every 7-10 days, and an appropriate amount of superphosphate should also be added to the fertilizer water.
In hot summer, place Aglaia odorata in a shaded spot; it can be placed at the edge of a shade frame, so that it is neither exposed to strong light nor able to get more sunlight. This is because overly strong direct light inhibits the growth and development of Aglaia odorata, while too much shade also easily causes it to grow leggy, become weak in growth and produce fewer flowers.
According to Aglaia odorata's temperature requirements, potted Aglaia odorata generally cannot be moved outdoors until after Grain Rain, and in autumn it must be moved indoors for overwintering before Frost's Descent. During overwintering, the room temperature is best kept at 10℃~12℃; if the room temperature is too high, it easily causes continued growth, which is unfavorable for growth and development the following year. But if the temperature is too low and drops below 5℃, it easily causes cold damage. When Aglaia odorata overwinters indoors, its leaves easily collect dust, affecting normal photosynthesis, so it needs to be rinsed once every so often.
Shaping should begin from the seedling stage, keeping a section of main trunk 15 cm~20 cm high, and not allowing the main branches to grow in a clump from the ground. Since Aglaia odorata produces flower spikes in the axils of new leaves, it is generally not pruned. If you want to control the tree shape and increase new branches, you can pinch back before new branches grow, or prune in combination with taking cuttings.
Pest and disease control for Aglaia odorata
Diseases of Aglaia odorata include stem rot, anthracnose, etc., and insect pests include the white moth planthopper, aphids, red spiders, scale insects, etc.
1. Stem rot: occurs on the stems of Aglaia odorata. At the beginning of the disease, it appears as small black spots, which after expanding become strip-shaped and dark brown; after encircling the stem, it causes the plant to die. In the early stage of the disease, you can apply 0.5%-1% Bordeaux mixture to the branches and trunk; you can also apply 1-2 degrees lime-sulfur mixture or 70% thiophanate 800-fold aqueous solution, which also has a relatively good effect.
2. Anthracnose: anthracnose is the main disease of Aglaia odorata and mostly occurs from June to October. In the early stage of the disease, the lesions invade from the leaf tip and leaf edge, causing the leaf tip to turn brown. It can occur on the plant's leaves, petioles and stems. Control method: when diseased leaves and branches are found, remove them promptly, and improve ventilation conditions. You can also spray with 1000-1200-fold potassium permanganate aqueous solution.
3. Red spiders: aphids etc. can all be sprayed with 40% dimethoate 1000-1500-fold aqueous solution, or with 1200-fold dichlorvos aqueous solution.
Key points for growing Aglaia odorata
1. Suitable temperature: Aglaia odorata likes warmth, and the higher the temperature, the more fragrant the flowers it produces. Generally speaking, at temperatures above 30℃, under sufficient sunlight, the flowers produced are strongly fragrant; conversely, in an environment below 30℃, if it is also in a shaded spot with insufficient light, the flowers produced are not as fragrant as at high temperature. To grow Aglaia odorata well, the suitable temperature range is between 20℃ and 35℃, and from June to October it can bloom as many as 5 times.
2. Sufficient light: Aglaia odorata should be placed in a sunny spot in all four seasons. If Aglaia odorata is placed in a courtyard or on a balcony with sufficient light and good ventilation, with more than 8 to 12 hours of light per day, the plant's leaves will be dark green, the branches will grow thick and strong, it will bloom many times, the flowers will be bright yellow, and the fragrance will be relatively rich. If Aglaia odorata is kept in an environment with insufficient sunlight and shade, the plant's branches and leaves will grow leggy and weak, the number of blooms will decrease, and the fragrance will be faint.
3. Reasonable fertilization: Aglaia odorata has strong flowering capacity and blooms many times, so nutrients must be replenished promptly. After each bloom of Aglaia odorata, nutrients should be replenished promptly; insufficient fertilizer is the main reason Aglaia odorata only grows leaves without blooming or drops leaves and buds. Therefore, when the temperature rises, Aglaia odorata should be moved outdoors for care, and after a week the soil should be loosened and some thin nitrogen fertilizer applied; 10% to 20% decomposed cake fertilizer water or human waste can be used, and afterward liquid fertilizer should be applied about once every 10 days to promote the growth of branches and leaves. Starting in June, Aglaia odorata enters the vigorous growth and flowering period, until mid-October. Every 15 days or so, apply a relatively concentrated fertilizer based mainly on phosphorus, or spray 0.3% potassium dihydrogen phosphate solution once every 15 to 20 days, and it will bloom even more abundantly. Pay special attention that during the flowering period phosphorus fertilizer must be the main type, otherwise the situation of only growing leaves without blooming will occur. During the flowering period from June to October, if fertilization is insufficient, not only will the number of blooms decrease and the flowers lose fragrance, but the flower buds that have already appeared will also wither and fail to open.
4. Water at the right time and in the right amount: the number of times Aglaia odorata is watered must depend on the size of the plant, changes in climate and the place where it is kept, achieving timely and appropriate watering. Applying more phosphorus and potassium fertilizer before flowering, together with frequent scattered sunlight and moderate watering, will make its flowers strongly fragrant. Summer is the vigorous growth period for Aglaia odorata, and its water demand increases accordingly; generally water once a day. In hot, clear weather, watering once each in the morning and evening is enough. If it lacks water, the leaves will turn yellow or even fall off. If there is a shower, after the rain tip the pot to pour out the water to prevent root rot.
How to grow Aglaia odorata: cultivation methods and precautions for Aglaia odorata
What the Flower and Bonsai Network introduces today is:How to grow Aglaia odorata, mainly introducing the cultivation methods and precautions for Aglaia odorata
Flower introduction: Aglaia odorata, with aliases mizailan, shulan, suimilan, yuzilan, woody zhulan, muzhulan, lanhuamu, sailanxiang, four-season mizailan, shuzhulan, is an evergreen shrub or small tree of the genus Aglaia in the Meliaceae family.
Aglaia odorata's flower meaning: with love, life will bloom.
Growing area: native to southern Asia. Widely planted in tropical regions around the world. In China it is distributed in Fujian, Guangdong, Guangxi, Sichuan, Yunnan and other places, and in the north it is mostly grown in pots.
Benefits of growing it: the leaves are lush and green, the tree form is graceful, and the flowers are golden and shining, giving it ornamental value; the flowers can be used to extract essence; the stem wood is fine-grained and can be used for carving and making furniture; Aglaia odorata can absorb sulfur dioxide and chlorine from the air, and it can also release volatile oil with bactericidal effects, purifying the air and benefiting human health.
Flowers and leaves: odd-pinnate compound leaves, alternate, with dark green leaflets. Panicle-shaped flowers, borne at the leaf axils at the ends of the tree, yellow flowers with a rich fragrance.
Variety selection: there are four commonly cultivated types of Aglaia odorata, namely Aglaia odorata, Taiwan Aglaia odorata, large-leaf Aglaia odorata, and four-season
Plant selection: healthy plants have glossy leaves and golden-yellow flowers.
Flower pot selection: a tall ceramic pot.
Preparation of culture soil: Aglaia odorata likes loose, fertile, slightly acidic soil, so the culture soil can be one based mainly on leaf mold.
Preparation method 1: mix compost, leaf mold and river sand in a ratio of 1:2:1.
Preparation method 2: mix leaf mold, manure and river sand in a ratio of 4:3:3.
Cultivation: place about 3~5 cm thick coarse sand or charcoal crumbs at the bottom of the pot as a drainage layer, then spread a small amount of culture soil on top, put the plant in the center of the pot, and while filling with soil press it firm so that the plant roots and soil are closely combined. After potting, water once thoroughly, then water sparingly over the next half month, keeping it in a semi-shady place for care to encourage new roots; afterward water promptly when the potting soil becomes slightly dry.
If it is a seedling, wait until it grows new leaves before gradually letting it receive light, and keep its environment humid. Note that after potting the temperature should be kept above 15 degrees Celsius.
Fertilization: after the temperature rises in spring, after Aglaia odorata has been moved outdoors for care for a week, loosen the soil and apply some thin nitrogen fertilizer; you can apply 10%~20% decomposed cake fertilizer water, and afterward apply liquid fertilizer about once every 10 days to promote the growth of branches and leaves.
Starting in June, Aglaia odorata enters the vigorous growth and flowering period, until mid-October. During this time, apply a relatively concentrated fertilizer based mainly on phosphorus once every 15 days or so, or spray 0.3% potassium dihydrogen phosphate solution once every 15~20 days; you can also do this appropriately to ensure more abundant blooming.
During the flowering period phosphorus fertilizer must be the main type, otherwise the phenomenon of only growing leaves without blooming will occur. From June to October, if fertilization is insufficient, situations such as flower buds withering without opening, fewer blooms and fragrance loss easily occur.
Watering: Aglaia odorata likes moisture but cannot be too wet. Generally water again when the potting soil dries to the point that the surface soil turns white; when watering, be sure to water thoroughly, judged by water flowing out from the bottom of the pot. At the same time, watering Aglaia odorata should vary according to the growth stage and seasonal climate changes.
Generally after Qingming, Aglaia odorata is moved out of the room. The amount of watering should begin to increase. Water less on cloudy days, do not water on rainy days, and on sunny days generally water once every 2~3 days.
In the high-temperature seasons of summer and autumn, Aglaia odorata is in its vigorous growth period and has a large water demand, so at this time it is generally watered once a day. On hot sunny days, sometimes it also needs watering once each in the morning and evening. But on rainy days, promptly pour out the accumulated water in the pot to prevent root rot.
In late autumn, as the weather gradually turns cooler, the growth of Aglaia odorata slows down. At this time watering should be gradually reduced to prevent leaf drop and root rot from over-wetness; generally watering once every 3~4 days is enough.
In winter, as the temperature drops, Aglaia odorata enters a dormant state and its water demand decreases. At this time it can be watered once every 10~15 days, keeping the potting soil moist but not excessively dry. If the potting soil is grayish-white, it proves the potting soil is already very dry, and it should be watered promptly at noon on a sunny day, otherwise the plant will die from long-term water shortage. Do not water in severe cold and continuously cold, cloudy weather. In winter, the water temperature used for watering should be close to or slightly higher than the potting soil temperature, to prevent harm to the root system.
Warm reminder: Aglaia odorata leaves easily drop; if you touch them slightly with your hand or shake the pot, the leaves will fall. This phenomenon indicates the plant is being overwatered, the petioles have already formed an abscission layer with the branches, chlorophyll has decreased, photosynthesis is affected, and as a result the plant becomes malnourished, weakens and dies.
Pruning: Aglaia odorata can be shaped from the seedling stage, keeping a section of main trunk 15~20 cm high, and not allowing the main branches to grow in a clump from the ground.
Because Aglaia odorata produces flower spikes in the axils of new leaves, new leaves are generally not pruned. But if Aglaia odorata has overwintered indoors, or is grown outdoors, a small amount of dead branches often appears, and these dead branches should be pruned at any time to keep the tree shape attractive and benefit plant growth. Therefore, when moving it outdoors in spring, a pruning can be done, cutting off dead branches, diseased and pest-damaged branches and thin, weak, overly dense branches, so as to enhance ventilation and light penetration and concentrate nutrients.
During its growth period, pruning is generally not needed, but if it grows too densely, some non-flowering inner branches or crossing branches can be pruned appropriately, and branches that grow irregularly or too tall can be cut back, to facilitate light and ventilation.
If after several years of pot cultivation the plant grows too tall, the overly dense and overly tall parts can be pruned away, so that it produces more side branches and more flowers. It can also be bent into shape to increase ornamental value. The material cut off can also be used for cutting propagation.
Light and temperature management: Aglaia odorata is a sun-loving flower, and only in an environment with sufficient light, sufficient fertilizer and good ventilation can it grow robustly; it is not cold-tolerant and is slightly shade-tolerant.
During the care of Aglaia odorata, it can be given sufficient sunlight in all four seasons; the daily light duration should be 8~12 hours or even longer, so that the plant will grow luxuriantly, with dark green leaves, thick branches, more flower buds, more blooms, brighter flower color and a richer fragrance. If Aglaia odorata is kept in an environment with insufficient sunlight, the plant will grow leggy, the branches will be weak, the number of blooms will decrease and the fragrance will become faint.
Aglaia odorata likes warmth, and the higher the temperature, the more colorful and fragrant the flowers it produces. The most suitable growth temperature is between 20 degrees Celsius and 35 degrees Celsius. So from June to October, the number of blooms can reach 5 times. When the temperature is above 30 degrees Celsius, under sufficient sunlight, the flowers it produces are very rich; if the temperature is below 30 degrees Celsius and the light is insufficient, the fragrance of the flowers it produces will decrease. When the winter temperature is below 10 degrees Celsius, it enters a dormant state, and below 5 degrees Celsius it is prone to cold damage.
Flowering and fruiting period management: the flowering period of Aglaia odorata is June to October each year. To make the plant bloom better and more, loosen the soil and fertilize frequently; each week apply fermented fertilizer liquid made from fish scraps, internal organs, eggshells and vegetable peelings, diluted with more than half water. When Aglaia odorata grows new shoots, remove the yellow-brown fuzzy leaf buds to reduce nutrient loss, and keep the green flower buds with white. In addition, maintain a sunny, warm and humid environment and fertile sandy loam so that it grows well. Prune branches and leaves promptly to ensure ventilation and light penetration; in such an environment, it can be prompted to grow healthily and bloom frequently.
Aglaia odorata can only grow well with sufficient sunlight and is not shade-tolerant, so after winter begins, the flowering period can be regulated by controlling the duration of light; in this way it is possible for it to bloom as usual during Spring Festival. If you need to delay the flowering time, you can reduce light; if you need to force flowering, you can extend the light duration, and at night you can add artificial light for a few hours, which can prompt the buds to open early.
Before the flowers bud, apply more phosphorus fertilizer so as to produce more buds.
Repotting: potted Aglaia odorata is generally repotted and given new soil once every two years, and the most suitable time is about a week after it is moved out in spring. Because the root system of Aglaia odorata is mainly fibrous roots, the roots are easily damaged when repotting. So, to damage the roots as little as possible, do not break up the old soil on the plant when repotting; keep more of the old soil and only remove the old soil where there are no roots, then use a knife to cut off the rotten roots.
Wash the pot clean or change to a new pot that has already been soaked, and change to new culture soil. When changing the soil, an appropriate amount of phosphorus fertilizer can be added to the bottom of the pot as base fertilizer, but not too much. After potting, place it in a cool, shady spot to recover; after about a week, move it to a sunny spot and enter normal management.
Propagation: the main propagation methods of Aglaia odorata are layering and cutting.
Layering propagation mostly uses the air layering method, and the best layering time is during the plum rain season.
Choose a one-year-old lignified branch, then make a ring bark cut at 20 cm from its base; a peel width of about 1 cm is enough. You can keep 2~3 small branches on the upper part, cut off all the lower side branches, then apply moss or peat to the girdled part. Note that the moss and peat must be disinfected beforehand before use. After wrapping, tie it tightly with plastic film at the top and bottom; do not let the lower part leak water, and the upper part can be tied slightly looser. Then promptly sprinkle water on the wrapped area to keep it moist; after 2~3 months it will root, after which cut it off from the mother plant and plant it.
Cutting propagation: this propagation method is mainly carried out from June to August. You can cut robust, already lignified branches of the current year as cuttings, about 10 cm long, keep 2~3 small leaves at the tip, cut off the lower leaves, and insert them into a cutting bed with peat as the medium or with sand and perlite as the medium, inserting about 4 cm. Then water thoroughly and seal the mouth of the cutting pot with plastic film to keep warm and moist. Keep the indoor temperature at about 28 degrees Celsius and the humidity at about 95%, keep the cutting bed moist, and after nearly 2 months it can root and be transplanted. If before cutting you soak the cut end of the cuttings in 500ppm naphthaleneacetic acid solution for about 20 hours, rinse them clean and then insert them, it can promote early rooting of the cuttings.
Overwintering: around Frost's Descent, when the temperature drops below 10 degrees Celsius, Aglaia odorata should be moved indoors. For home potting, generally as long as the indoor temperature in winter is not lower than 5 degrees Celsius, it can overwinter safely. Even if the branch tips drop leaves because the weather is slightly cold, after trimming and repotting in the following spring and then strengthening water and fertilizer management and careful care, it will quickly sprout new leaves and bloom again.
If particularly cold weather occurs, you can cover the plant with two layers of plastic bags to keep it warm, and poke a few small holes in the plastic bags for ventilation. Every 1~2 days, remove the plastic bags to let it breathe fully, otherwise the leaves will turn yellow.
The indoor temperature is best kept between 8 degrees Celsius and 10 degrees Celsius. If the temperature is too high, the top branches easily sprout new buds and consume nutrients, and when moved outdoors in spring they easily suffer withered tips, directly affecting the next year's growth and flowering.
During overwintering, also avoid indoor temperatures fluctuating between high and low, and do not frequently change the placement location.
During the overwintering period, keep the potting soil moist; too dry will cause yellow leaves to fall, and too wet will lead to leaf drop and root rot. When the air is dry, you can spray water on the leaf surface; the best time to spray is at noon on a sunny day, and the temperature of the sprayed water should be similar to the potting soil temperature. If stains appear on the leaf surface, clean them so that it can breathe normally.
If for a period of time, due to various factors such as going out, you cannot water Aglaia odorata, you can place the Aglaia odorata pot on a shallow tray with moist soil, letting the plant absorb a tiny amount of water from the bottom of the pot.
If withered and decayed leaves are found, remove them promptly so that they do not consume too many nutrients and also affect appearance.
After moving indoors, also pay attention to ventilation, but do not place it in a drafty environment, to avoid freezing damage.
The time to move it outdoors should be after Qingming, and only when the temperature is basically stable above 15 degrees Celsius should you consider moving it outdoors. Before moving it outdoors, first let it adapt to the outside environment; you can open the windows and let Aglaia odorata gradually adapt to the outside air, and after a transition period, move it outdoors.
Pest and disease control: the diseases of Aglaia odorata mainly include stem rot, anthracnose, Aglaia odorata chlorosis, etc.; insect pests mainly include the white moth planthopper, aphids, red spiders, scale insects, etc.
Stem rot: if the plant develops stem rot, promptly apply 0.5%~1% Bordeaux mixture or 70% thiophanate 800-fold solution to the branches and trunk in the early stage of the disease.
Anthracnose: anthracnose is the main disease that Aglaia odorata is prone to, often breaking out from June to October. Diseased leaves begin from the leaf tip and leaf edge and gradually turn brown. If the petioles and stems are infected with this pathogen, they will also gradually turn brown.
To control this pathogen, after discovering diseased branches and leaves, promptly cut off the diseased parts to cut off the source of infection, and then improve ventilation conditions.
You can also spray 1000~1200-fold potassium permanganate aqueous solution.
Aglaia odorata chlorosis: this disease is relatively common and mostly occurs at the turn of spring and summer in the hot, rainy season. Diseased plants have new leaves lacking green, withered branch tips, and in severe cases it even leads to the death of the whole plant. This disease is mostly caused by alkaline soil; improve the soil so that it becomes slightly acidic, and loosen the soil.
Red spiders, aphids: if the plant is affected by the above-mentioned pests such as red spiders and aphids, they can all be killed by spraying with 40% dimethoate 1000~1500-fold aqueous solution or 1200-fold dichlorvos aqueous solution.
Best placement location: outside a south-facing window.
