Rose Introduction

Rose is a plant of the genus Rosa in the family Rosaceae. It can be propagated by sowing and cuttings. The precious varieties are difficult to propagate by cuttings, so they can be propagated by layering and grafting.

Rose cultivation method

Roses prefer an environment with plenty of light, and can also accept partial shade. It is best if the cultivation environment has good light. It does not have high requirements for the soil, and can grow in ordinary clay. When planting, you can apply some base fertilizer. The maintenance temperature is best at 15-20℃. Roses are plants that are afraid of waterlogging, so do not water them too much during maintenance, just keep the soil slightly moist.

When growing roses, you need to choose loose, fertile, well-drained, slightly acidic soil. When watering, it is best to follow the principle of "watering when dry and watering when wet". Roses need sufficient sunlight to grow. They are full-sun plants. When they are growing vigorously, apply decomposed fertilizer water once every half a month, and apply phosphorus and potassium fertilizers 2-3 times before flowering.

Watering method

Roses begin to resume growth in spring. The air humidity is relatively high at this time, so you can check the potting soil every half a month to see if it needs watering. In summer, when it grows vigorously, water it every 10 days. You can spray water in moderation to keep it moist. In autumn and winter, when the temperature is lower, reduce watering and keep the potting soil dry.

Fertilization method

Rose is a plant that likes fertilizer, so it should be fertilized according to the method of "thin fertilizer and frequent application". Every winter, you can combine soil cultivation with fertilization once to ensure that the tender branches and flower buds have enough nutrients, the branches and leaves are more luxuriant, and the flowers are more beautiful. During the flowering period, the frequency of fertilization becomes one to two times a week, so as to ensure the flower production.

Pruning methods

Roses can be pruned when new buds sprout. Cut the branches above the buds. Dead branches should be cut off immediately. Weak, overlapping or cross-growing branches and leaves should also be pruned. After the flowers fade, trim the remaining flowers and clear the weeds around the plants.

Precautions for rose cultivation

2. Roses are prone to powdery mildew if they are placed in conditions of poor ventilation, insufficient light, heavy rain and moist soil, and the branches and buds need to be cut off immediately.

3. When managing roses, be sure to pay attention to ventilation and frequent pruning of branches and leaves, otherwise it is easy to be infected with diseases. Once the disease is found, it must be treated as soon as possible and sprayed with pesticides to avoid worsening.
