What is the best fertilizer for roses?

Rose fertilization time

Roses can be fertilized during the germination stage, bud stage, flowering stage and after flowering. Generally, roses can be fertilized four times a year. The first time is in March and April, the second time is before flowering, the third time is after flowering, and the fourth time is in late autumn and early winter to apply overwintering fertilizer to improve its cold resistance.

What fertilizer to use for roses

When roses are just planted or repotted, base fertilizer should be applied. Use decomposed fertilizer. Topdressing should be done once after 15 days. Before flowering, apply fertilizer containing phosphorus and potassium to promote flower bud differentiation. After flowering, apply organic fertilizer to replenish lost nutrients. Wintering fertilizer should be applied in late autumn and early winter, mainly to accelerate nitrogen, phosphorus and calcium fertilizers.

Rose Fertilization Method

It is best to bury fertilizer for roses in the soil, not directly on the surface. Burying it in the soil can allow the roots to absorb better and promote the growth of the plant, but it should not be too close to the roots to avoid burning the roots. After fertilizing, it is necessary to water it in time to dilute it.

Rose fertilization precautions

Roses like fertilizer, but the amount used each time should not be too much, so as to avoid fertilizer damage and endanger its growth. If fertilizer damage occurs, it is necessary to water it with plenty of clean water to flush it. However, if the situation is more serious, it is best to change the soil as soon as possible and replace it with new soil to avoid root rot.
