Edible Mushroom Preservation Methods and Remedies for Over-Fertilizing Flowers

Due to a lack of experience, many flower growers apply too much fertilizer, causing plants to suffer fertilizer damage. When plants suffer fertilizer damage, the main symptoms are as follows: the branches and leaves above ground quickly wilt and the leaf color becomes dull, while the underground root system discolors and rots. So once fertilizer damage occurs in a plant, what should be done?

Remedies: Wash the Roots and Repot

Immediately take the affected flower out of its pot, wash the roots clean and cut off the damaged part of the root system, and cut off the severely wilted branches and leaves. Then replace the growing medium, repot, water thoroughly, and place it in a shady spot away from direct sunlight. Mist it 3-5 times a day to ensure a balance of moisture above and below the plant, until the flower and tree return to normal growth.

Water Thoroughly

For some valuable flowers and trees or those with delicate roots, it is not advisable to wash the roots and change the soil. Instead, immediately water the affected plant thoroughly 2 to 3 times in a row so that the high-concentration fertilizer is flushed out.

Rinse

Place the flower pot in flowing clean water and rinse for 1 to 2 hours, with the water level 2 to 3 cm above the pot rim, so as to quickly reduce the fertilizer content of the potting soil. Correct Fertilization Methods Rather than thinking of ways to rescue a plant after it suffers fertilizer damage, it is better to learn the correct fertilization methods.

Fertilization should be seven parts water and three parts fertilizer. Especially when using compound fertilizer, the concentration should be 0.1%-0.3%, then spray it onto the potting soil with a spray bottle. Do not spray too much; it is best if the solution flows out from the drainage hole.

Solid fertilizer should be used in an appropriate amount according to the size of the plant and the size of the flower pot. For stick-shaped special fertilizer, generally bury 1-2 sticks in a flower pot about 10 cm in diameter, and bury 3-4 sticks in a flower pot more than 12 cm in diameter.

The concentration of topdressing should be low. For example, the spray concentration of urea should be lower than 0.1%, the concentration of superphosphate should be 0.1%-0.3%, the spray concentration of ferrous sulfate should be 0.2%-0.5%, and the concentration of micronutrient fertilizer should be 0.1%-0.2%. For bulbous and fleshy-stemmed flowers, and shade-loving foliage flowers, use less fertilizer; succulent flowers should be fertilized less than shade-loving foliage plants; for fibrous-rooted flowers, each topdressing amount should be 20%-25% of the normal amount; fruit-ornamental and flower-ornamental types should be fertilized more.
