Next, Qinnong.com will guide everyone through the cultivation methods for the Tea Rose.

1. Soil environment for the Tea Rose

Roses are not very demanding about soil and can grow in ordinary mixed soil, but to grow them well, it is best to use loose, fertile, slightly acidic soil. Ordinary mixed soil can have a suitable amount of ferrous sulfate added. When growing in pots, first spread a layer of base fertilizer at the bottom of the pot. Since the roots of this flower are mainly distributed in the 30-40cm deep soil layer, when plowing, to ensure the soil is loose and breathable, the plowing depth should be about 60cm.

2. Water management for the Tea Rose

The water requirement of the Tea Rose varies with the season and the amount of growth. Spring and autumn are the peak flowering periods, and at this time both the amount and frequency of watering should be moderately increased to ensure sufficient water for the flowers to bloom fully. At the same time, attention should be paid to the soil's water-holding capacity. If the soil's water-holding capacity is weak and the soil has low stickiness, the watering frequency should be reasonably increased; otherwise, the amount and frequency of watering should be correspondingly reduced, or else the roses will suffer root rot. If the roses are to be pruned, control watering before pruning to stabilize the rose's growth, and after pruning increase watering to promote the plant's growth.

3. Fertilizer management for the Tea Rose

The Tea Rose likes organic fertilizers such as compost and has a relatively high fertilizer requirement. On average, each rose needs about 15 kilograms of fertilizer. Moreover, the Tea Rose has a long flowering period, usually from June to September, and in some areas it can bloom as early as May. Therefore, during its development, attention should be paid to frequent fertilization, generally with potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer as the main topdressing, which can effectively promote its growth and benefit flowering.

4. Pruning and care of the Tea Rose

It was mentioned earlier that if the Tea Rose is to be pruned, its growth should be controlled before pruning. In fact, the best time to prune the Tea Rose is during its dormant period. When pruning, simply shorten the branches and cut off the new buds growing inward. After it has grown stably for one year, all thin and weak branches can be cut off, and healthy branches can be cut back by half, which helps improve the quality of flowering. The Tea Rose is famous for its huge flowers, so the more mature the plant, the more it needs pruning. Usually, Tea Roses over three years old need to be pruned every year to maintain an attractive overall shape.

5. Pest and disease management for the Tea Rose

The main pests and diseases of the Tea Rose are black spot, powdery mildew, red spider mites and aphid infestation. During care, attention should be paid to timely sterilization and pest removal. The plum rain season and the hot, humid, high-temperature summer are the main disease periods, and the spraying frequency can be appropriately increased to prevent the occurrence of pests and diseases.
