Rose is not only beautiful in appearance, but also often blooming in four seasons, with many colors, different colors and fragrance. It is widely used in horticulture and cut flowers. Do you know how to raise potted roses?

How to raise potted rose well

1. Basin

It refers to the selection and change of pots. It is better to burn the pot with soil, and the diameter of the pot should be commensurate with the plant size. When using the basin, the old basin should be washed, and the new basin should be soaked in the tide before use. When the plant continues to grow until the root has been filled with the original basin, it should be replaced with a large basin during the dormant period to meet the needs of the continued development of the root. After growing up, the living seedlings should be replaced from small pots to large ones, preferably once a year.

2. Soil

The culture soil needed for potted plants should be mixed with 50% garden soil, 30% rotten waste soil and 10%-20% coarse bran ash. Add 10-15 kg of rotten compost or cake fertilizer for every 500 grams of soil. When you change the basin, you should also use the new culture soil.

3. Water

That's watering. Water is the lifeline of plant growth, too much and too little will affect the growth. In particular, the watering of potted rose should be adjusted appropriately according to the needs, and the amount of watering should be controlled according to the change of season and the water consumption of growth. Low temperature in spring, just long leaves, low water demand, once every 3-5 days, hot summer, watering 1-2 times a day (except overcast and rain), watering thoroughly, especially in the bud and flowering period, if there is no shortage of water supply after dormancy, it is necessary to reduce the amount of water, do not accumulate water in the rainy season.

4. Fat

The rose is fattening. This flower grows fast, blossoms more, and consumes a lot of nutrients, so fertilization is an important part of keeping rose. Potted plants must be fully fertilized. Under normal circumstances, thin fertilizer is applied every 7-10 days, so that the leaves often remain thick green and shiny. Thicker liquid fertilizers such as soy sauce residue water can be applied before the emergence of flower buds to meet the needs of flowering. The principle of applying fertilizer in a small amount of time should be grasped at ordinary times. Whether to continue to apply fertilizer in the heat of summer, depending on the growth of the plant, vigorous growth can continue to apply; weak growth, thin flowers, semi-dormant state, should stop fertilization.

5. Light

Although the rose likes the sun, it should try to block the direct light in the hot summer. It is best to place it in the shade around noon, so that you can see the sun day and night. After changing the basin, put it in a cool place to avoid direct sunlight, and move to a ventilated and sunny place a week later.

6. Harm

That is, diseases and insect pests. In the spring and autumn rainy season, leaves are prone to black spot and powdery mildew. After discovery, it can be treated with 1000 times liquid spray of 70% wettable topjin powder, or cotton can be dipped in alcohol to wipe the positive and negative sides of flowers and leaves and petioles. The main pests are aphids and red spiders, which can be sprayed 1500 times with 40% dimethoate EC.

Matters needing attention

If the temperature difference is large, the sun-dried water should be selected when watering, so as to reduce the temperature difference between basin soil and water, avoid overcooling of water and stimulate root development.

If you are not going to harvest flower seeds, it is best to cut off the residual flowers before they bear seeds.

If excessive fertilization causes leaf burning, it should be watered immediately.
