What are the cultivation methods and precautions for rose potted plants?

Rose Introduction

Roses belong to the Rosaceae family. The methods of reproduction include cuttings, grafting, and division. Common cultivated varieties include Corolla roses, Diana roses, champagne roses, and cold beauty roses.

Rose cultivation method

Roses prefer a sunny environment and are not cold-resistant. They are suitable for planting in well-drained, loose and fertile loam or light loam. They need more than 8 hours of sunshine during the growing season and are not very strict about air humidity. They will develop rust and powdery mildew in low temperature and humidity, which requires timely prevention and treatment.

soil

  Roses like loose soil and are best planted in sandy soil with good drainage. If planted in airtight clay, the roots will have difficulty absorbing nutrients and water, which can easily lead to poor growth and difficulty in flowering.

illumination

  Rose is a light-loving plant, so it is important to ensure sufficient light during the growth period. It is best to provide more than 4 hours of direct sunlight a day. If the maintenance environment is not well ventilated and there is insufficient light, it will cause problems such as yellowing leaves. When the temperature is low in winter, it needs to be moved to a window location indoors for maintenance.

Watering

Watering should be carried out according to soil conditions, climatic conditions and the growth status of branches and leaves. During the maintenance of roses, if the soil is too dry, it will cause the main leaves of the plant to fall off. When the surface is dry, water should be applied in time to keep the soil moist.

Fertilization

The fertilizer for roses can be compound fertilizer rich in nitrogen, phosphorus and potassium, which is generally sold on the market. Do not use too much topdressing, apply thin fertilizer frequently, and do not use concentrated fertilizer.

prune

When winter just begins, roses need to be pruned to prevent some useless branches from being wasted. In spring, some old branches should be cut off first to make room for the growth of new branches. After new buds grow, the new buds on the main branches should be cut off.

Rose cultivation precautions

After the roses fade, the withered flowers need to be pruned. In addition, you can also take this opportunity to cut off the branches that have grown too long. Common diseases and pests of roses during their growing period are red spider mites, black spot disease, and branch dieback. You can do a good job of disinfection during greenhouse cultivation. In high temperature conditions, pay attention to ventilation and spray Bordeaux mixture or thiophanate-methyl solution in time.
