Chinese Rose Spring Management Methods
Today, the editor will share some tips on roses and Chinese roses, the spring management methods of Chinese roses, and let's get to know them together.
As the saying goes, a year's plan depends on spring. In spring, everything revives and the temperature gradually rises. Chinese roses also begin to sprout. In order to make the Chinese roses flourish in the later period, it is necessary to manage the Chinese roses in spring. Let's take a look at the spring management of Chinese roses.
1. Adapt to the External Environment
Chinese roses usually sprout in mid-to-late March. In protected overwintering cultivation areas, preparations should be made before growth; for those planted in the ground, remove the anti-cold materials and water thoroughly; for those stored in cellars, open the cellar lid for ventilation and sunlight; for Chinese roses overwintering indoors, open the windows for ventilation, allowing the plants to gradually adapt to the warming climate conditions of early spring. (Friendly reminder, be cautious when taking plants out of the house, avoiding sudden temperature changes)
2. Sufficient Sunlight
Chinese roses are sun-loving flowers and need to be exposed to sunlight for at least 4-5 hours a day. Although the temperature may rise in early spring, it is still cold in the morning and evening. Therefore, when it is warm and sunny, you can move the potted plants to an outdoor ventilated and sunny area around 10 am to bask in the sun, and then move them back around 2 or 3 pm. This can increase the temperature of the potting soil and accelerate the growth of Chinese roses.
3. Shaping and Pruning
The purpose of pruning Chinese roses is to concentrate the limited nutrients and form a full and complete tree shape. Spring pruning should remove excess suckers and long branches, leaving 1-2 full buds on each branch, removing the rest, and for grafted seedlings, remove the root buds. The direction of the buds should be noted to control the plant shape to be full and beautiful.
4. Watering and Fertilizing
Water according to the dryness of the potting soil, following the principle of "no watering when not dry, watering thoroughly when watering". Watering should be done around noon and the water temperature should be slightly higher than the soil temperature. For Chinese roses that have just been repotted, since there is sufficient fertilizer in the potting soil, no additional fertilizer is needed in the first month. After new buds grow, depending on the nutrient consumption of the potting soil, a thin liquid fertilizer with more phosphorus can be applied once a week. With the above careful management, by mid-to-late May, Chinese roses will bloom colorful flowers.
5. Repotting
If there is a need to repot, in order not to affect the continuous growth of potted Chinese roses, repotting must be done before the tender buds and new roots start to sprout (early to mid-March). This minimizes plant damage. Do not water before repotting to avoid loose soil. When repotting, remove the entire plant from the pot, use a bamboo stick to remove some of the old soil around the plant, retain the protective root soil, avoid excessive root damage, and剪去 old, diseased, decayed, and weak roots to promote new root growth. Use a pot slightly larger than the original one, place a layer of coarse charcoal or broken tiles at the bottom for drainage, then add a layer of decomposed hair, hooves,碎骨 or slow-release organic fertilizer with more phosphorus, and finally fill with potting soil (do not overfill the pot), tamp down, water thoroughly, and place in a well-lit indoor area.
6. Preparing Potting Soil
If repotting soil is necessary, use ordinary potting soil for cuttings that have taken root, and for perennial plants, a mixture of three parts field soil, one part sand soil, and one part decomposed manure soil can be used. The soil should be loose, well-draining, breathable, and rich in humus.
7. Disease and Pest Control
Combined with repotting and pruning, spray a 0.5-degree lime sulfur mixture once and frequently spray fungicides to prevent diseases. The main pests include aphids, red spiders, and scale insects, which should be eliminated in a timely manner.
(1) Aphids A few can be brushed off with a brush dipped in water, and the pesticide can be sprayed with 40% dimethoate or dichlorvos emulsion diluted 1500 times.
(2) Red Spider You can place a burning mosquito coil in the pot of the plant and cover the pot with plastic wrap. After about an hour of smoke熏, both eggs and adult insects will be killed.
(3) Scale Insects If found, you can use a brush or small brush dipped in chili water to apply to the entire plant of Chinese roses, which is effective in killing scale insects and also has significant control effects on other diseases and pests (chili water is made by mixing 1 kilogram of water with 20-30 grams of dried chili peppers).
The above is the complete introduction to the spring management methods of Chinese roses, for everyone to learn and understand!
