What to Do If You Over-Fertilize Plants? Learn the Correct Remedies
Many people like growing plants, but improper methods often lead to embarrassing situations. So what should you do if you over-fertilize plants? Today, let's find out together!
1. What to Do If You Over-Fertilize Plants
After over-fertilizing plants, promptly water them with some water so the clean water dilutes the fertilizer in the soil. Alternatively, take the over-fertilized plant out of its original pot; after removing the soil, wash the roots of the flowers.
2. Fertilizing Precautions
(1) Fertilize according to different flowers and trees and different growth stages. For example, chrysanthemums need gradually increasing amounts and concentrations of fertilizer during bud formation. Acid-loving flowers and trees such as gardenia, azalea, camellia, and jasmine should not be given alkaline fertilizers such as ammonia water or sodium nitrate. Bulbous flowers and trees that need heavy pruning every year should be given more phosphorus and potassium fertilizer. Half a month before frost, apply wintering fertilizer to improve the plant's cold resistance; before early spring budding, apply sprouting fertilizer to make the buds plump and sprout quickly; when the spring shoots are about to mature, apply bud-promoting fertilizer to promote flower bud differentiation and plump buds; after flowering, apply a thin nutrient fertilizer to restore tree vigor and promote reblooming or fruiting. During full bloom and the early fruit-setting stage, fertilizer and water must be controlled, otherwise flowers and fruits are prone to dropping. Seedlings grow rapidly, so apply more nitrogen and potassium fertilizer. Before flowering and at bud emergence, apply more phosphorus fertilizer.
(2) Loosen the soil before fertilizing, and also be careful not to let fertilizer water fall on leaves or buds. Acidic fertilizers such as human manure and urine, superphosphate, and ammonium carbonate cannot be mixed with alkaline fertilizers such as plant ash and ammonia water. Alkaline potting soil should use acidic fertilizer, and acidic potting soil should use alkaline fertilizer. Never apply a single kind of fertilizer; applying nitrogen fertilizer together with phosphorus and potassium fertilizer can improve fertilizer efficiency; applying inorganic fertilizer together with organic fertilizer can prolong fertilizer efficiency, and can also prevent potting soil from compacting and improve properties such as aeration, water permeability, water retention, and fertilizer retention.
