What are the rose propagation methods? A detailed explanation of common propagation techniques

Rose propagation methods: every year from April to May or September to October is the best time to propagate roses. There are many ways to propagate roses; here are 4 methods:

(1) Cuttage. Choose vigorous, semi-lignified branches of the current year, cut them in the morning while dew is still on them, preferably with a heel, about 10-15 cm long, keep two leaves and cut off the rest, then immediately insert them into a shallow mud tray to a depth of one cun, then water thoroughly with a spray bottle, and place in a cool spot for care; roots will develop after about one month.

(2) Dormant-period cuttage. This can be done from after leaf fall until before the Beginning of Spring sprouting; the cuttage method is the same as above, except without leaves. After inserting, you can cover with a transparent plastic bag and place in a sunny spot. After sprouting in early spring, remove the plastic bag, and once the leaves turn green they can be transplanted.

(3) Bud grafting. Bud grafting can be done during both the growing period and the dormant period; after bud grafting, flowers can appear in as little as 6 weeks. The method is: choose a good rootstock, remove the thin branches, keep the thickest branch, choose a smooth surface, and use the tip of a knife to cut a "T" shape 3 cm above the soil surface. Use the knife tip to pry open the bark, then choose a strong bud from the middle of a branch as the scion, cut off the leaf but keep the petiole, and slowly cut downward from below the petiole into a shield shape, peel off the xylem, and immediately insert it into the "T"-shaped cut in the rootstock, then tie it tightly with a plastic bag from top to bottom. Grafted seedlings should be placed in a cool spot for care.

(4) Water propagation. This method is simple and easy to succeed with, and is not limited by season. Fill a brown wide-mouth bottle with clean water, then make a hole in the center of a cork or foam plastic stopper, cut it into two semicircles, insert the cutting into the small hole and fix it at the bottle mouth, then place it at a cool window; change the water once every 3 days, and roots can develop in about 1 month. The above is an introduction to rose propagation methods.

How to grow fragrant roses: fragrant rose growing methods

Because roses have many varieties, a long flowering period, and beautiful flower colors, they are very ornamental, and more and more people keep a pot indoors; the fragrant rose is one of them. Today, we will introduce fragrant rose growing methods.

1. Soil

The soil is best as loose, slightly acidic soil (pH around 6.5); ferrous sulfate can be used for appropriate treatment, the land should be deeply plowed, the surface raked flat, and cultivation in a sunny bed is best. For potted plants, use 30% garden soil, 30% pond mud, 30% humus, and 10% fine coal cinder or more, all by mass ratio, mixed evenly for use; when planting, it is best to apply a pinch of fine cake fertilizer at the bottom of the pot. Most of the fragrant rose's root system is concentrated in the top 30-40 cm of soil, so the depth of the cultivation layer should be 50-60 cm.

2. Water

Water management for fragrant roses is also an important task; insufficient or excessive water will inhibit their growth and development, so it needs to be adjusted according to the different growth and development stages. Spring and autumn are the peak flowering periods for fragrant roses, and during this time the water supply should be sufficient; before pruning the fragrant rose plants, watering should be paused to control plant growth, and after pruning the amount of watering should be appropriately increased. In addition, if cultivated in sandy soil with poor water retention, the frequency of watering should be appropriately increased; in soil with poor drainage, watering should be done cautiously to prevent root rot.

3. Fertilizer

Fragrant roses like fertilizer, especially organic fertilizer such as barnyard manure and compost. The application amount of organic fertilizer is about 150 kg per 10 plants. Fragrant roses have a long flowering period, so during their growth, chemical fertilizer should be applied as a top dressing for quick effect; the ratio of nitrogen, phosphorus, and potassium in the top dressing should be 1:1:2 or 1:2:3. The commonly used chemical fertilizer is superphosphate, applied at an average of 2 kg per 100 sq m.

4. Pruning

After young plants are cultivated in spring, all flower buds of the first and second flushes should be removed (cut off one leaf below the bud) to save nutrients and promote branch and stem growth; for large plants, cut off the spent flowers, and for grafted seedlings, promptly remove the suckers on the rootstock; in summer and autumn, cut off the spent flowers after blooming. Cut off overly long branches, crossing branches, overlapping branches, leggy branches, and capped shoots, etc. This makes good preparation for viewing during Christmas, New Year's Day, and the Spring Festival.

Pruning is intended to let fragrant roses sprout as many strong branches as possible, thereby improving flower quality. In addition, pruning can also make the tree shape complete and balanced, coordinating it with the space it lives in. The most suitable time for pruning is when the plant stops dormancy and is about to sprout, or when it stops growing and is near dormancy. The forms of pruning include light pruning, moderate pruning, and heavy pruning, 3 kinds. Light pruning is shortening healthy branches and removing inward-growing buds; moderate pruning is cutting off healthy branches of the previous year at the base or cutting off half; heavy pruning is keeping only 3-4 previous-year branches on the whole plant, then shortening them 20 cm above the ground. For newly transplanted plants, if the plants have already been pruned before planting, there is no need to prune again within the first year of planting. After one year, thin and crossing branches can be cut off at the base, and among the retained strong branches at least half their length should be cut off. Fragrant roses planted for more than 3 years still need annual pruning to maintain a perfect plant shape.

5. Pest and disease control

Common rose diseases are black spot and powdery mildew, so attention should be paid to the prevention and management of seedling pests and diseases; maintaining vigorous plants itself resists invasion by miscellaneous fungi under natural cultivation techniques. Before planting large and small seedlings, sterilization and insecticide disinfection work should be done well according to the actual conditions of the greenhouse and soil. In spring, alternately use 500-800 times dilutions of mancozeb, chlorothalonil, carbendazim, and thiophanate-methyl once each (Bordeaux mixture and lime sulfur are also acceptable); if red spiders or aphids are found, imidacloprid or abamectin can be used for control, and they can also be mixed with fungicides. The yellow plum rainy season and autumn rainy period are peak periods for black spot, and the disease is also severe in hot, humid, and rainy summer; during this period, the interval between applications should be shortened. Note when spraying: generally 8-10 a.m. and 4-7 p.m. Spraying on a sunny, windless day is best.

6. Growing precautions

Fragrant roses are light-loving plants, so during cultivation choose a sunny location and avoid planting beside tall buildings, under tree shade, or on the shady side of slopes.

In areas where the lowest winter temperature is below minus 15°C, some antifreeze measures should be taken. For example, pile 20 cm of soil at the base of the plant, or wrap the plant clump with straw curtains, hemp bags, plastic film, etc. In areas where the lowest winter temperature reaches minus 20°C, it is necessary to loosen the soil on one side of the plant, lay the plant down, and cover it completely with soil.

Angela rose growing methods

Propagation methods

Angela rose propagation methods are divided into three types: cuttage propagation, grafting propagation, and tissue culture propagation, among others, 3 ways.

Cuttage propagation: the method is to take 3-5 vigorous young shoots, treat them with rooting powder, and insert them into a substrate made of peat and perlite; the insertion depth should reach 1-2 buds, and after 15-30 days milky-white adventitious roots grow from the base.

Cuttage precautions: for planting, clean and heat-fried river sand can be used, which can play a sterilizing role and better allow the cuttings to survive.

Grafting propagation: before grafting, first find the rootstock; the rootstock should mainly be a plant of the same genus, then graft. Bud grafting method: choose a very vigorous young bud and peel it off with the bark, cut a "T"-shaped opening in the rootstock, 1 cm wide and 1.5 cm long, insert the bud into the opening, tie tightly with a plastic strip, and it survives after 30 days. Branch grafting method: split grafting is done 3-5 cm above the ground on the rootstock, with a vertical cut of 2 cm; the scion is required to be an unexpanded young shoot, with thickness comparable to the rootstock; after grafting, tie firmly with a plastic strip, and it heals and survives after 10 days.

Tissue culture propagation: terminal buds or young leaves are commonly used as explants; after disinfection, inoculate them on MS+6BA2+NAA0.1 medium, and after 5 weeks 25% of terminal buds develop into new shoots, then transfer to 1/2MA+NAA1 rooting medium, and after about 3 weeks about 70% of the shoots root, becoming complete small rose plants.

Angela planting methods

Angela rose planting methods: Angela roses can be planted in pots or in garden soil; if newly planting Angela roses, appropriate pruning is needed, generally leaving 4-5 buds is enough.

1. Requirements: if planting in pots, choosing the flower pot is very important; generally old flower pots should be cleaned thoroughly, and new flower pots should be soaked and moistened before use, and a flower pot of suitable size should be chosen.

2.: For potted plants, culture soil is used, generally 50% garden soil, along with 30% decomposed garbage soil, 10%-20% coarse chaff ash, and at the same time add 500 g of soil plus 10-15 kg of decomposed compost or cake fertilizer.

3. Water: water appropriately according to temperature; in spring, water about once every 3-5 days, and in summer, water 1-2 times a day.

4. Fertilizing: Angela roses like fertilizer; generally apply a thin fertilizer once every 7-10 days, and fertilize appropriately when there are flower buds.

5. Roses generally prefer sunlight, but in summer, appropriate shading treatment should be given to roses to avoid sunburn.
