How to grow potted ivy? Cultivation methods and precautions
Ivy is a rather popular large indoor potted foliage plant, especially when placed in a fairly spacious living room, study, or sitting room, where it lends an elegant, simple style with a touch of southern charm. It is a world-famous new-generation indoor foliage plant with a graceful, neat plant shape. Now let's take a look at how to grow ivy!
The growing environment of ivy
Ivy is a shade-loving climbing plant, but it can also grow in full-light conditions. It grows well in warm, humid climates and is not cold-tolerant. It is not demanding about soil, preferring moist, loose, fertile soil, and is not tolerant of saline-alkaline conditions.
It often climbs on trees at the forest edge, on roadside plants under the forest canopy, on rocks and house walls, and is also commonly cultivated in gardens.
Propagation methods of ivy
1. Seed propagation
For seed propagation of ivy, harvest the seeds when the fruit ripens, pile them up for after-ripening, soak and rub them in water, wash the seeds clean and dry them in the shade, then sow them; they can also be stored mixed with damp sand and sown in spring the following year. After sowing, cover with 1 cm of soil and cover with grass to keep moist. When the seedlings emerge, set up a shed for shade. In the second spring, transplant or thin the seedlings, then grow them on into larger plants.
2. Cutting propagation
The cutting propagation method for ivy is to take softwood cuttings with aerial roots during the growing season, which root most easily. After inserting the cuttings, build a closed plastic-film arch tunnel and shade it, keeping the air humidity at 80%-90%, but the bed soil should not be too wet, so as to avoid rot of the cuttings. Roots form in about 30 d.
3. Layering propagation
Layering propagation of ivy is done in spring and autumn, using the wavy layering method; after ring-barking the part to be buried, it roots very easily, making it a relatively simple propagation method.
Cultivation methods for ivy
1. Suitable temperature: Ivy likes warmth, with an optimum growing temperature of 20°C-25°C. It fears heat and is not cold-tolerant. Therefore, when keeping it indoors, pay attention to ventilation and cooling in summer, and in winter the room temperature is best kept above 10°C, and must not fall below 5°C.
2. Appropriate light: Ivy likes light and is also fairly shade-tolerant. Grown under semi-light conditions, its internodes are shorter, its leaf shape is uniform, and its leaf color is vivid, so it is best grown in a bright spot indoors. If in spring and autumn you can each choose a period to place it in a shaded spot outdoors so that it gets more morning and evening sunlight, it will grow vigorously with bright green leaves. But be careful to prevent direct strong light, otherwise it is prone to sunscald.
3. Moderate watering: During the growing season, water according to the principle of "dry-wet alternation"; do not let the potting soil become excessively wet, otherwise it easily causes root rot and leaf drop. In winter, when room temperature is low, especially control watering and just keep the potting soil slightly moist. The northern winter climate is dry, so it is best to spray-wash the plant once a week with clean water at a temperature close to room temperature to maintain air humidity; the plant will then look lively, with tender green, glossy leaves.
4. Reasonable fertilizing: For home cultivation of ivy, the potting soil should preferably be a culture soil made by mixing leaf mold or peat soil with 1/4 river sand and a small amount of bone meal. During the growing season, apply dilute cake fertilizer water once every 2-3 weeks. Generally, do not fertilize in summer and winter. When fertilizing, never apply nitrogen fertilizer alone, otherwise the patterns and patches on the leaves of variegated varieties will fade to green. The ratio of nitrogen, phosphorus, and potassium is best at 1;1;l. In the peak growing season, you can also spray the leaves 1-2 times with 0.2% potassium dihydrogen phosphate solution, which will make the leaf color even more beautiful. But note that when applying liquid fertilizer, avoid soiling the leaves, so as to prevent leaf scorch.
Pest and disease control of ivy
The main diseases of ivy include leaf spot, anthracnose, bacterial leaf rot, leaf spot, root rot, and blight, while among pests, leaf rollers and borers, scale insects, and red spider mites cause relatively serious damage.
1. Anthracnose
[Damage characteristics] Anthracnose mainly harms the leaves; when damage is severe, the leaves turn grayish-white. It is likely to occur during continuous autumn rain.
[Control methods] Place in a ventilated, light-transmitting spot, and do not water directly onto the leaves. After onset, spray 50% carbendazim wettable powder at 500 times dilution, once every 7 days, for 3-4 consecutive sprays to control it. For other methods, see the pest and disease control section for Schefflera.
2. Leaf spot
[Damage characteristics] It easily causes leaves to yellow and drop, mostly caused by poor ventilation and a stuffy, humid environment.
[Control methods] In the early stage of the disease, remove diseased leaves and burn them in a centralized manner. At the same time, spray 1% Bordeaux mixture once every 7 days, for 4-5 consecutive sprays.
3. Scale insects
[Damage characteristics] Affected plants grow poorly and can also be contaminated by sooty mold, causing leaves to yellow and drop prematurely.
[Control methods] Remove them manually by scraping. When the affected area is large, you can also spray 40% omethoate emulsifiable concentrate at 800 times dilution. For other methods, see the pest and disease control section for sago palm.
4. Blight
[Damage characteristics] The whole leaf or most of the leaves turn brown and rot, or the base of the stem and the base of tender nodes become dark green and water-soaked, soften and constrict, then turn brown to brownish-black, and the branches and leaves above the diseased part wither. Some directly form rotten tops or dead heads; sometimes the stem base of cuttings also becomes diseased and produces stem rot. When cuttings carry the pathogen or the soil carries the pathogen, and soil and air humidity are high, the disease occurs easily and spreads rapidly.
[Control methods] ① Remove diseased plants promptly and control watering appropriately. ② When planting cuttings, choose cuttings from plants free of pest and disease damage, and insert them into a sterilized substrate or one where blight has never occurred. Do not plant too densely, and pay attention to ventilation and light transmission. ③ Drain promptly during the rainy season to prevent moisture retention. ④ In the early stage of the disease, spray or drench with 25% metalaxyl wettable powder at 800 times dilution, or 58% metalaxyl mancozeb wettable powder at 600 times dilution, 64% oxadixyl wettable powder at 600 times dilution, or 72% Curzate at 600 times dilution.
5. Gray mold
[Damage characteristics] Water-soaked brown or black lesions form on leaf edges; when severe, the lesions can cover most of the leaf or the entire leaf, and a gray mold layer forms when humid.
[Control methods] Use disease-free new soil for cultivation, control watering, and do not apply too much nitrogen fertilizer. Remove diseased leaves promptly and burn them. At onset, spray 75% chlorothalonil at 500 times dilution, once every 10 days, for 2-3 consecutive times.
6. Purple prominent oyster scale
[Damage characteristics] Nymphs and female adults suck sap from branches and leaves. When severe, they cover the leaves and branches, causing the plant to dry up, yellow, and die.
[Control methods] In winter, combine with shaping and prune off pest-infested branches and leaves, and burn them in a centralized manner. During the nymph hatching period, spray 50% phoxim at 1000 times dilution or Supracide at 1500 times dilution.
7. Sunscald
[Damage characteristics] Upper leaves or new leaves turn light gray, gradually wither, and drop.
[Inducing cause] A physiological disorder. In summer, moving ivy that has long been kept in a shaded place suddenly into bright sun makes it easily scorched by strong sunlight.
[Control methods] The cultivation environment should preferably be semi-shaded, with about 50%-70% sunlight. Avoid direct strong sunlight.
Cultivation precautions
During ivy cultivation, paying attention to some details can help ivy grow more luxuriantly.
1. Although ivy is simple and easy to cultivate and manage, it still needs to be grown in an environment with air circulation and moist soil; the best time to transplant it is in early autumn or late spring.
2. After ivy is planted, the branches need to be pruned to promote branching.
3. In winter, keep ivy warm and maintain air humidity, but the potting soil should not be too wet. At the same time, pest and disease control is also needed for ivy, and nutritional management should be strengthened.
Cultivation methods and precautions for ivy
Ivy's habits: it likes warm, shaded environments and avoids direct sunlight, but likes ample light; it is fairly cold-tolerant and highly resistant, and is not demanding about soil and water, with neutral and slightly acidic soil being best. Morphological characteristics and uses: a perennial evergreen woody climbing plant. It grows by climbing, with stems reaching more than 20 m, bearing aerial roots, and scales on young branches. The leaves have two forms: one is the triangular or halberd-shaped leaf on sterile branches, with entire margins or three shallow lobes; the other is the lanceolate leaf on fertile branches, with entire margins and a slender petiole. Ivy is a large indoor potted plant, generally used to decorate spacious living rooms and studies. How to grow ivy well is what many friends care about most. Next, Xiao Qi will tell everyone about ivy's cultivation methods and precautions.
Cultivation methods for ivy
Ivy, a shade-loving climbing plant, can generally be grown well in the climate of the south. It is often cultivated along roadsides, on house walls, in courtyards, and so on.
1. Temperature: Ivy likes warmth, with an optimum growing temperature of 20°C-25°C. It fears heat and is not cold-tolerant. Therefore, when keeping it indoors, pay attention to ventilation and cooling in summer, and in winter the room temperature is best kept above 10°C, and must not fall below 5°C.
2. Light: Ivy likes light and is also fairly shade-tolerant. Grown under semi-light conditions, its internodes are shorter, its leaf shape is uniform, and its leaf color is vivid, so it is best grown in a bright spot indoors. If in spring and autumn you can each choose a period to place it in a shaded spot outdoors so that it gets more morning and evening sunlight, it will grow vigorously with bright green leaves. But be careful to prevent direct strong light, otherwise it is prone to sunscald. Although it is a shade plant, it is rather unusual in that it quite likes light for its leaves. So people who like growing flowers and plants generally grow it under semi-light conditions. Indoors, it is recommended to place it in a spot with fairly sufficient light. In summer, provide appropriate shading. In spring and autumn, it is best to provide morning and evening light and shade it during other periods.
3. Watering: During the growing season, water according to the principle of "dry-wet alternation"; do not let the potting soil become excessively wet, otherwise it easily causes root rot and leaf drop. In winter, when room temperature is low, especially control watering and just keep the potting soil slightly moist. The northern winter climate is dry, so it is best to spray-wash the plant once a week with clean water at a temperature close to room temperature to maintain air humidity; the plant will then look lively, with tender green, glossy leaves. Watering for humidity is the trick to keeping ivy evergreen. First, make sure the soil it is grown in is neither too wet nor too dry; it is recommended to keep the soil neither dry nor wet. Water when the soil has dried out.
4. Fertilizing: For home cultivation of ivy, the potting soil should preferably be a culture soil made by mixing leaf mold or peat soil with 1/4 river sand and a small amount of bone meal. During the growing season, apply dilute cake fertilizer water once every 2-3 weeks. Generally, do not fertilize in summer and winter. When fertilizing, never apply nitrogen fertilizer alone, otherwise the patterns and patches on the leaves of variegated varieties will fade to green. The ratio of nitrogen, phosphorus, and potassium is best at 1;1;l. In the peak growing season, you can also spray the leaves 1-2 times with 0.2% potassium dihydrogen phosphate solution, which will make the leaf color even more beautiful. But note that when applying liquid fertilizer, avoid soiling the leaves, so as to prevent leaf scorch. Ivy is not very demanding about fertilizer; it is generally recommended to provide some fertilizer for nutrients in the early growth stage. Fertilizing is not recommended in summer and winter. After flowering, appropriate fertilizer can be provided for the nutrients needed for flowering the following year.
5. Prune in time: When the small seedlings are potted (preferably 3 plants per pot) and grow to a certain height, pay attention to timely pinching to encourage more branching, so that the plant shape looks full.
6. Set up a support for potted plants: To let it climb upward and add infinite charm to the beautification of the room space, or to grow it as a hanging basket, with soft branches and vines naturally drooping and swaying, extremely elegant, blending into the delightful enjoyment of evergreen vitality through all four seasons. Therefore, it is a rare hanging vine foliage treasure for modern living rooms, offices, conference rooms, and similar places. Generally, repot once every one or two years.
Precautions for cultivating ivy
For cultivating ivy, in fact, ordinary rough and extensive care is enough. However, to keep it evergreen, some things also need attention. During high summer temperatures, it is recommended not to place it in strong sunlight. During the day, place it in a ventilated spot and sprinkle a little water on the leaves to lower the temperature. The most important thing is to avoid fertilizing, otherwise the leaves will yellow under the effect of high temperatures. In seasons with a lot of rain, cultivation in the south easily causes water accumulation due to overwatering. In such seasons, generally reduce watering as much as possible. That way, root rot can be avoided.
1. Ivy cultivation and management are simple and extensive, but it needs to be planted in a place with moist soil and air circulation.
2. In summer, maintain it under a shade shed; in winter, place it in a greenhouse to overwinter. Indoors, air humidity should be maintained and it should not be too dry, but the potting soil should not be too wet.
3. Pay attention to pest and disease control.
The main diseases include algal leaf spot, anthracnose, bacterial leaf rot, leaf spot, root rot, and blight. Among pests, leaf rollers and borers, scale insects, and red spider mites cause relatively serious damage.
Control methods: First, in late autumn or early spring, clear away fallen leaves and promptly prune and burn diseased branches and leaves; second, before onset, spray 65% zineb at 600 times dilution for protection; third, fertilize and water reasonably, and pay attention to ventilation and light transmission;.

The value of ivy
1. Ornamental and eye-pleasing
Ivy is most commonly planted on outdoor walls or in courtyards, or grown indoors in hanging baskets. Wherever it is, it is full of vitality, climbing like a gecko and spreading out like a spider web; every late spring and summer we see a mass of emerald green. Its leaves are like maple leaves, and at each flowering season it also opens small pale yellow-white flowers, very beautiful and fresh. It has become a popular greening ornamental plant. Whether in outdoor environments or indoors, it can bring a mass of emerald green and bring hope; especially indoors it is a very eye-pleasing green plant that can play a role in decoration and beautification.
2. Freshening the air
It can enhance the naturalness and freshness of the owner's living environment. Moreover, it is a very healthy and eco-friendly ornamental plant. It can not only green the environment but also purify the air, absorb indoor waste gases, and release oxygen through photosynthesis, among many other effects.
3. Medicinal value
Ivy also has good medicinal value. The whole plant can be used as a Chinese herbal medicine. It can clear heat and reduce fire, has a good protective and nourishing effect on the human liver, relieves pain in body parts, and can also reduce swollen abscesses, with a good disinfecting and sterilizing effect. In addition, ivy also has a good beautifying effect, able to firm the skin and reduce edema.
