How to grow potted roses? Methods and precautions explained in detail

Growing methods for potted roses

Growing environment

Roses love sunlight, so when grown indoors, keep them on a sunny balcony. The soil for potted roses should be loose, fertile and well-drained. Note that roses grow poorly and bloom badly in clay loam. They should be planted in a well-ventilated spot far from walls to prevent sunlight reflection from scorching the buds and affecting blooming.

Watering roses

Potted roses should not be watered too much. Roses are drought-tolerant and hate waterlogging, so strictly follow the principle of "don't water until dry, and water thoroughly when you do." If you water roses frequently (especially avoid overwatering on humid, rainy days with low evaporation), root rot and plant death easily occur.

Fertilizing roses

Potted roses should be given light fertilizer; avoid strong fertilizer (especially chemical fertilizer), which can cause partial root rot and death. According to the size of the plant and pot, every 1-1.5 months evenly apply 20-40 granules of compound fertilizer (or nitrogen fertilizer) about 1 inch below the soil at the edge of the pot, or water once or twice a month with lightly fermented rice-washing water or similar mild liquid fertilizer. As long as the leaves are green, the flowers are bright and the growth is good, no further fertilizing is needed.

Routine pruning

Normally no pruning is needed; for older plants, just remove overly dense branches, faded branches and diseased or pest-infested branches. Roses bloom, and the flowers should be picked as soon as they fade; picking them encourages more blooms, otherwise they flower only once. To make roses grow well and bloom abundantly, pruning is very important. Generally, when overwintering, cut back all branches to about 10 cm above the ground so the plant can overwinter smoothly.

Pest and disease control

For potted roses, the main pests are caterpillars and scale insects. Caterpillars are easy to treat, but once scale insects break out, they are harder to control, can infest the whole plant and lead to disease. Therefore, controlling scale insects is the key point in home rose growing. To control scale insects, place the roses in a well-ventilated, well-lit place, and cut away the numerous branches of the rose, keeping a few main branches so the interior is ventilated. Keep the potting soil moist, but not waterlogged. When white spots are found on the rose branches, scrape them off promptly with a bamboo strip. If the infestation is severe, directly cut off the entire branch or even all branches, and combine this with spraying scale-insecticide. Roses are not afraid of pruning; rose pruning is introduced below.

Precautions for growing potted roses

① Potting time. It is best done in early winter after leaf fall or in early spring before buds sprout.

② Fertilizing and watering. Roses love fertilizer. After potted roses have settled in, apply 1 application of decomposed organic liquid fertilizer every 10 days, and during the bud formation stage apply some liquid fertilizer containing phosphorus and potassium. Water according to weather conditions; in hot summer, water every day, and at other times water thoroughly whenever the potting soil looks dry. After blooming, promptly remove spent flowers.

③ Pruning. Because pruning must be done during the dormant period, this can promote vigorous plant growth and extend the flowering years.

④ Pest and disease control. See the related content on common rose diseases.

To make roses bloom abundantly, with bright colors and lush leaves, when growing them in open ground, note the following:

① Choice of planting site. It is best to plant in a well-drained, sunny, high spot; avoid planting in low-lying areas to prevent waterlogging. The soil should be loose and fertile.

② Fertilizing and watering. Before planting, apply decomposed organic fertilizer as a base fertilizer. Plant before the buds sprout. During the growing period, apply 1-2 topdressings of organic liquid fertilizer mainly based on nitrogen, and before flowering apply 1 liquid fertilizer mainly based on phosphorus and potassium. After leaf fall, dig trenches around the plant and apply leaf-mold fertilizer, then irrigate and cover with soil. In early spring when buds sprout and during dry seasons, and in midsummer, pay attention to watering so the soil does not become too dry; at other times, water according to whether the soil is dry or moist.

③ Division. Because roses have strong suckering ability, pay attention to division, usually once every 2 years, keeping 5-6 branches per plant.

④ Pruning. During the dormant period, the plant must be pruned, which can promote vigorous growth.

⑤ Pest and disease control.
