What fertilizer is best for roses?

Fertilizing roses

Roses like fertilizer and need to be fertilized frequently during the growing season. Generally, the most favorite fertilizers for roses are phosphorus and potassium fertilizers. It is best to fertilize roses during the growing season and flowering period. It is best to apply organic fertilizer as base fertilizer when roses are first planted.

Roses can be treated with compound fertilizers. It is generally better to use diluted organic fertilizer liquid when applying topdressing. Roses require more nutrients during the flowering period, so phosphorus and potassium fertilizers need to be applied in time. After the flowering period, decomposed manure, bean cake or oil residue needs to be applied to supplement nutrients.

How to fertilize roses

1. When roses are first planted, sufficient organic fertilizer needs to be applied as base fertilizer.

2. During the growth period of roses, nitrogen-containing compound fertilizer needs to be added to promote the growth of branches and leaves.

3. Roses need additional fertilizer in the early stage of flowering, and you can apply decomposed cake fertilizer.

Homemade Rose Fertilizer

When fertilizing roses, you can also make your own fertilizer. You can ferment expired milk or used rice water, or you can ferment vegetable leaves, bean shells, or peanut shells.

Fertilizer damage to roses

When the rose suffers from fertilizer damage, the leaves will turn yellow. At this time, you need to stop fertilizing and pour plenty of water into the potting soil to flush and dilute the fertilizer. If the fertilizer damage is serious, you need to replace the potting soil and check whether the roots of the rose are damaged. If so, you need to cut them off in time.
