What is the best fertilizer for roses?

Rose fertilization time

1. Roses need to be fertilized four times a year. The first time is around the Qingming Festival, the second time is before picking the flowers, the third time is in May, and the fourth time is in late autumn and early winter. The fertilizer applied each time is different, but it is mainly organic fertilizer.

2. Topdressing of roses should be carried out according to the growth conditions. In the budding stage, compound fertilizer should be applied in time to promote the rapid growth of the plant's branches and leaves. The second time is in the bud stage, when the root growth reaches its peak, and fertilizer should be applied in time. The third time is in the flowering period, and quick-acting fertilizer should be applied in time. After flowering, decide whether to apply topdressing based on the growth conditions.

What fertilizer to use for roses

The fertilizer applied to roses should be determined according to the season or growth stage. When they are first planted, base fertilizer should be applied, and decomposed fertilizer should be used. Topdressing should be done once every half a month. Nitrogen, phosphorus and potassium fertilizers should be applied before flowering to promote flower bud differentiation. Organic fertilizers should be applied after flowering to supplement nutrition. Overwintering fertilizers should be applied in late autumn and early winter, using nitrogen, phosphorus and calcium fertilizers to improve cold resistance.

Rose fertilization method

When fertilizing roses, you can bury the fertilizer in the soil instead of sprinkling it directly on the surface. This will dilute it faster and the plants can absorb it better. But be careful not to bury it too close or too deep. After burying it, water it appropriately to dilute it and it will soon be absorbed by the plants.

Notes on fertilizing roses

Although roses are fertilizer-loving plants, do not fertilize too much at one time, otherwise the roots will easily rot, and in severe cases the plants will be burned to death. Therefore, excessive fertilization must be treated as soon as possible. You can rinse it with plenty of clean water. If the situation is serious, it is best to change the soil as soon as possible to avoid root rot.
