Is flower fertilizer applied too much? Don't worry. This is what we should do.

Due to lack of experience, many flower growers will fertilize too much, causing plants to suffer from fertilizer damage. When plants suffer from fertilizer damage, there are mainly the following phenomena: the branches and leaves of the aboveground parts wilt rapidly, the leaves are dim, and the underground roots change color and rot. So what should we do once the plants suffer from fertilizer damage?

Remedial measures for excessive fertilization in flower cultivation

1. Clean the root and change the basin

Immediately remove the injured flowers from the basin, clean the roots and cut off the damaged parts of the roots, cut off the damaged roots and yellowed, dry branches and leaves, and dry the wound to prevent wound infection, then change the culture soil, re-pot, water thoroughly, and put it in a cool place, do not let direct sunlight, spray water 3-5 times a day, ensure the water balance between the plant and the plant, until the flowers and trees return to normal growth.

2. Pour water thoroughly

For some precious flowers and trees or delicate flowers and trees with delicate roots, it is not suitable to wash their roots and change the soil. The damaged flowers and trees should be watered for 2 or 3 times in a row in order to discharge high concentration fertilizer.

3. Flushing

Wash the flowerpot in flowing water for 1 hour or 2 hours, the water surface should be 2 cm higher than the basin surface, in order to quickly reduce the fertilizer content of the basin soil, and put the flowers in the shade.

Correct fertilization posture

1. Fertilizing should be "7% water, 3% fertilizer", especially when using compound fertilizer, the concentration should be 0.1%-0.3%, then spray it to the basin soil with a spray can, do not spray too much, and it is appropriate for the solution to flow out of the outlet.

2. Solid fertilizer should be used appropriately according to the size of plants and flowerpots. For rod-shaped special chemical fertilizers, generally the diameter of flowerpots is about 1 / 2 in 10cm, the diameter of flowerpots is larger than 12cm, and 3 / 4 flowerpots are buried.

3. The concentration of topdressing should be low, and fertilization should be carried out timely and appropriately according to the main principle of "applying thin fertilizer frequently". For example, the spraying concentration of urea is less than 0.1%, the concentration of calcium superphosphate is 0.1%-0.3%, the concentration of ferrous sulfate is 0.2%-0.5%, and the concentration of micro-fertilizer is 0.1%-0.2%. Bulbs, fleshy stem flowers, shade foliage flowers should be less fertile; succulent flowers should apply less fertilizer than shade foliage plants; fibrous root flowers, the amount of topdressing each time is 20%-25% of the normal amount; fruits and flowers should be fertilized more.

4. in the process of fertilization, for some delicate flower varieties, we must pay attention to that fertilizers do not touch the roots of branches and leaves of flowers, so as to prevent the occurrence of burns and seedlings.
