1. Soil quality: use suitable soil to cultivate raspberry, which is good for the root respiration and growth. It is best to use loose, drainage effect of some soil, try not to use heavy, poor soil, not conducive to its root growth.
2. Moisture: during the maintenance, the soil should be kept in a slightly wet state at all times, and the water needs to be replenished in time when it dries. Especially in the dry weather, we must not be too short of water, and there should be no excess water, otherwise it will affect its flowering and bearing.
3. Sunlight: it likes sunshine. When breeding, we should keep it in the sunshine as much as possible. If we don't see the sun for a long time, the amount of flowers will be reduced.
4. Fertilizer: a certain amount of fertilizer shall be applied at the beginning of planting, and appropriate topdressing is required at the vigorous growth period, which can be applied 2-3 times a year. The fertilizer used is mainly nitrogen fertilizer, but also a small amount of phosphorus and potassium fertilizer.
Pay attention to pruning after harvesting fruit, should be more dense growth, disease and insect branches are pruned off, not only conducive to plant ventilation, but also to control the overall amount of branches.
