How to fertilize roses? What fertilizer is best?

1. Fertilization time

Roses should be fertilized mainly when they are growing vigorously, especially during their flowering period, which is May and June. In addition, if there is insufficient nutrients in the soil when planting or repotting, you can also use appropriate basal fertilizer.

2. Fertilizer Types

The fertilizers used during the growth period are mainly liquid fertilizers, which can be purchased directly and have better effects. Solid fertilizer is mainly used when planting or repotting.

3. Fertilization method

1. The liquid fertilizer used during the growth stage cannot be used directly, but needs to be diluted with water first and then sprinkled on the soil surface. During the flowering period, special attention should be paid to liquid fertilizers containing phosphorus. Applying solid fertilizer is not that troublesome. You can just mix it in after preparing the soil. Just make sure to stir it evenly.

2. Another thing is the frequency of fertilization. During the seedling stage, the amount of fertilizer required is relatively low, and fertilization can be controlled once every 20 days or so. If the plant is an adult, it will require slightly more fertilizer, and it is better to control it to once every 15 days or so.

IV. Precautions

When roses are in a dormant period, since their growth is basically stagnant, you can temporarily apply fertilizer.
