The potting method of Chinese roses
Answering netizens' questions about the potting method of Chinese roses, let's learn about it together.
1. Choosing a pot
Clay pots are the best, followed by purple sand pots. Ceramic pots cannot be directly planted with Chinese roses and can only be used as display or decorative pots.
The size of the pot should not only match the diameter of the plant's canopy but also consider the planting location. Generally, one-year-old plants should choose a small pot with a diameter of 15-20 cm, two-year-old plants use a pot of 20-25 cm, and three-year-old plants need a large pot with a diameter of more than 30 cm. If the location is more shaded, the pot can be smaller, while for places with good sunlight and high evaporation, a larger pot should be chosen.
2. Potting soil
It is best to use potting soil that is fertile, well-ventilated, loose, rich in organic matter, and with a pH of 6-7. Generally, every 100g of dry cultivated soil should contain 10-30mg of pure nitrogen, 60-80mg of phosphorus, and 80-150mg of potassium.
3. Potting
Try to pot the plant with soil. If the protective soil has fallen off, prepare the pot by filling the bottom and sides with the prepared cultivated soil before moving the plant into the pot. While arranging the roots, fill the soil and shake the pot occasionally to make the soil adhere closely to the roots, filling the soil slightly higher than the root collar. For grafted seedlings, the grafting joint should be 2-3 cm above the soil surface. Place the pot in a shaded area for 10-15 days before moving it to the potting area. It is best to first plant the seedlings in a smaller pot, and after new roots have formed and a soil ball has been created, then transplant them with the soil ball into the fixed planting pot.
4. Repotting
Chinese roses grow rapidly and must be repotted every year. For plants over three years old, they should only be turned over, not repotted, or changed to ground planting after renewal pruning.
5. Soil, fertilizer, and water management
The watering principle is the same as for ground planted Chinese roses. Watering should be done once a day for both large and small pots, but do not water during rainy days and be sure to empty the water after rain to prevent water accumulation in the pot. To keep the potting soil loose and breathable, the soil should be loosened every 10-15 days.
Chinese roses consume a lot of fertilizer during the blooming period, generally applying fertilizer every 10-15 days. During the peak blooming period, a 0.2% phosphorus acid potassium or 0.05% boric acid solution can be used as foliar fertilizer. The principle of fertilizing potted plants is: fertilize in spring and summer, less in autumn and winter; more for large flowers, less or none for small flowers; more for strong plants, less or none for weak plants; more during the bud stage, less during the blooming stage; more during the fruit expansion stage, none or less during the initial fruit setting stage; fertilize when changing the potting soil, and do not fertilize for newly planted seedlings.
