How often should roses be fertilized? Fertilization time and method

How often should roses be fertilized?

Around May every year, when the rose enters a rapid growth period, it will be accompanied by continuous flowering. At this time, it is necessary to fertilize the plant every 40-60 days. After the plant blooms, fertilizing the plant needs to be stopped.

What fertilizer to use for roses

1. Organic fertilizer : Generally, before planting roses, you need to apply an appropriate amount of decomposed organic fertilizer to the soil as base fertilizer, which can promote vigorous growth of the plants.

2. Phosphorus and potassium fertilizers: Before the rose blooms, you can apply some phosphorus fertilizers and potassium fertilizers to it. This can promote the differentiation of flower buds of the plant and the formation of flower buds in the later stage.

Rose fertilization method

1. Apply base fertilizer

When planting roses, whether in potted plants or planted in the ground, base fertilizer needs to be added. You can mix an appropriate amount of chicken manure fertilizer or bean cake fertilizer into the soil, which will allow the plants to grow and germinate better.

2. Fertilize during flowering period

The rose plant blooms in summer and autumn, and its demand for nutrients is relatively large, so a thin layer of fertilizer should be applied every 10 days or so, and potassium dihydrogen phosphate fertilizer should be sprayed frequently, which can promote the plant's flower color to be more colorful.
