What are the cultivation methods for the Tea Rose?

The Tea Rose (Rosa odorata) is an evergreen or semi-evergreen climbing shrub of the Rosaceae family native to southwestern China. It is currently a rare species under Class III protection in China and is also an important parent of excellent rose cultivars. The Tea Rose has large flowers in a wide variety of colors and a delightful fragrance, so it is widely cultivated and hybridized and has spread throughout the world, making it an ornamental flower loved worldwide. Next, Qinongwang will guide everyone through learning about the cultivation methods for the Tea Rose.

I. Soil environment for the Tea Rose

Roses are not very demanding about soil, and ordinary mixed soil is enough for them to grow, 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, and when growing in pots, a layer of base fertilizer should first be spread 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.

II. Water management for the Tea Rose

The water requirement of the Tea Rose varies according to the season and the amount of growth. Spring and autumn are the peak flowering seasons, 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 rose will suffer root rot. If the rose is to be pruned, watering should be controlled before pruning to stabilize the rose's growth, and after pruning the watering amount should be increased to promote the plant's growth.

III. 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 kg 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 the development process, attention should be paid to frequent fertilizing, generally with potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer as the main topdressing, which can effectively promote its growth and benefit flowering.

IV. 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 pruning period for the Tea Rose is its dormant period. When pruning, simply shorten the branches and cut off 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 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 the beauty of the overall shape.

V. Pest and disease management for the Tea Rose

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

The above is the planting method for the Tea Rose brought to you by Qinongwang. The Tea Rose is not strict about soil and prefers warm, sunny areas, but dislikes intense heat. When growing it in pots, you can give it some sunshine from time to time!
