What happens if you fertilize roses too much? Should you sprinkle the fertilizer on the surface or bury it in the soil?

1. What happens if you apply too much fertilizer?

Although it is a plant that likes fertilizer very much, do not fertilize it too much. Too much fertilizer will be difficult for the plant to absorb, and it will cause fertilizer damage, easily burn the roots and cause root rot. In severe cases, the entire plant will die. Therefore, if too much fertilizer is applied, timely treatment is required. You can dilute it by watering. Large amounts of fertilizer will flow out with the water, which can reduce fertilizer damage. If the situation is more serious, it is best to dig the entire plant out of the soil, replace it with new soil and maintain it to avoid fertilizer damage.

2. Fertilization method

When fertilizing it, it is best to bury the fertilizer in the soil so that the fertilizer can be diluted faster and easier for the plant to absorb. If you spread the fertilizer directly on the surface, it will be slow to dilute and absorb slowly. But be careful to dig shallow trenches, not too deep, otherwise the roots will be easily damaged. And it cannot be too close to the root system, otherwise the surface will burn the roots. In addition, attention should be paid to the number of times fertilization is applied. Generally, it is done once every half a month during the growing season. In short, thin fertilizers should be applied frequently.

3. Fertilizer selection

The specific type of fertilizer to be chosen should be based on the stage, as the fertilizer required for different growth stages is also different. When the seeds sprout in spring, apply decomposed fertilizer, or you can also use human and animal manure. Phosphorus and potassium fertilizers should be applied before the flowers bloom, which is conducive to the differentiation of flower buds. After flowering, apply organic fertilizer to replenish the consumed nutrients. At the beginning of winter, compound fertilizer should be applied to improve its cold resistance, which will help it survive the winter.
