Roses should be kept in loose, fertile soil, with a little basal fertilizer to provide nutrients. Maintain sufficient light every day, but can not be subjected to strong direct light. During the growing period as the temperature rises, watering should be increased. Fertilizer is mostly applied during the growing period, with a light fertilizer every 10 days. Propagation is usually done by cuttings, which have a high survival rate. If it suffers from pests and diseases, you need to remove the diseased branches and leaves and spray with pesticides to control.
A, maintenance methods
1, soil: roses do not require much soil, in neutral, slightly alkaline and slightly acidic soil can grow. In order to promote its development, you can add a certain amount of base fertilizer to the soil to provide it with certain nutrients.
2, light: roses are suitable for growing in a relatively light environment. Put in the shade for a long time will make it grow poorly, resulting in a thin plant, leaves yellowing and falling. But also to avoid strong light exposure, sunburn leaves and flowers.
3, watering: the growth of roses can not be separated from sufficient water. Watering can be done when the surface of the potting soil is white, to keep the substrate moist. In its growing period, as the temperature rises, to increase the amount of water. And the dormant period should not be watered too much, otherwise it will lead to drowning roots.
4, fertilization: roses have a greater need for fertilizer. In the growing period, every ten days to water a light fertilizer, in the flowering period and winter can not be fertilizer. However, after the flowers are shed, a liquid fertilizer should be applied to supplement the nutrition, and organic fertilizer should be applied before winter to overwinter.
Two, propagation skills
There are many ways to propagate roses, including sowing, cuttings, grafting, high pressure and so on. Among them, cuttings are more convenient, and the survival rate is very high. Generally carried out in the fall and winter, selecting strong-growing branches, retaining a few buds and upper leaves. Insert the branch into the loose moist soil, keep 18-25 ℃, after a month can root.
Three, pest and disease control
1, disease: common diseases are black spot disease, powdery mildew and so on. Need to cut the diseased branches and leaves, and spray polymyxin sterilization. Pay attention to ventilation in daily maintenance to avoid bacterial growth.
2, pests: aphids and plants are the main pests. You need to remove the pests and then spray oxolinic acid to exterminate the larvae.
