Fertilization according to season

Spring and summer are the vigorous periods of plant growth. During this period, the plant grows rapidly and has a great demand for nutrients. The "three element" fertilizer dominated by nitrogen fertilizer should be applied; A small amount of phosphorus and potassium fertilizer can be applied in autumn to improve the cold resistance and overwintering ability of plants; Winter flowers enter the dormancy period, and a small amount of fertilizer can be applied to meet the growth needs

Fertilize according to plant growth

Strong plants grow fast and need more nutrients. They should be thin and fertilized frequently; The diseased plant grows slowly and needs less fertilizer. You can apply less fertilizer or no fertilizer

Fertilization according to plant growth period

Plants should be applied with phosphorus and potassium fertilizer at the flower bud stage, which can promote flower bud differentiation and make plants bloom more; Fertilization should not shorten the flowering period of the plant, otherwise it will shorten the flowering period; When the plant bears fruit but the fruit is not stable, fertilization will lead to fruit drop. It is appropriate to apply phosphorus and potassium fertilizer when the fruit is stable, especially during the fruit expansion period, so as to promote the growth of the fruit

Fertilize according to plant type

Alkaline fertilizer is forbidden for some plants, such as azalea and gardenia; For the flowers that need to be re cut every year, the proportion of phosphorus and potassium fertilizer should be appropriately increased to promote the germination of new branches; Nitrogen fertilizer is suitable for flowers that mainly watch leaves; Phosphorus and potassium fertilizer is suitable for the flowering period of fragrant flowers; Fruit observation flowers should be applied with sufficient fertilizer in the strong fruit period to improve the amount of fruit< span>
