What should be paid attention to in summer flower fertilization?

First, for potted flowers, it is not suitable for fertilization around noon in the summer, because the soil temperature is higher, the applied fertilizer is easy to damage the roots, and the best is applied in the evening.

The second is the organic fertilizer that can be used. Only the above liquid can be used. Dry matter cannot be applied. If dry matter is applied, it will ferment and heat in the soil, thereby damaging the root system and producing small black worms.

Third, the concentration of summer top dressing is low, and it is not necessary to apply fertilizer that is not fully decomposed.

Fourth, the summer dormant flower fertilization should be less to prevent rotten roots.
