What fertilizer do you need

Generally, nitrogen fertilizer can promote strawberry to form a large number of leaves and stolons and increase the number of fruits. If there is lack of nitrogen, the leaves will turn yellow, and some will be scorched, and the leaves will be slightly smaller than normal leaves; Phosphorus fertilizer can promote flower bud differentiation and improve fruit setting rate. When strawberry is short of phosphorus, the upper leaves will show purple spots, and the flowers and fruits will be small; The role of potassium fertilizer is mainly to promote fruit ripening, increase sugar content and improve quality. When potassium is deficient, the edges of strawberry leaves will appear black, brown and dry. In serious cases, they will become burned, the fruit color will be light and the taste will become worse. In addition, strawberries are very sensitive to chlorine, so the use of chlorine containing fertilizer should be controlled

Pot fertilization

Apply enough base fertilizer before planting, and fertilize reasonably during the growth period, so as to ensure its strong growth. At the same time, it will have more flowers, large fruits and more fruit setting. There is no problem that the base fertilizer can choose long-term slow-release fertilizer or other organic fertilizers

Topdressing should be the most popular choice for flower friends, because many people forget the base fertilizer. In order to meet the needs of strawberries for various nutrients during the flowering and fruiting period, general fertilizer can be applied before it begins to grow until the flowering period. If there is a base fertilizer, it can not be applied. Fertilizer with high nitrogen and potassium can be applied during the expansion period of berries. After a large number of fruits, they lack nutrients. In order to promote the recovery of plant growth, new leaves and roots can be formed, Topdressing shall be carried out according to specific conditions

Remember, strawberry should not be fertilized too much, because strawberry roots are more sensitive to fertilizer
