1、 When to fertilize

Fertilizing trigonometry plum needs to be carried out in spring, early summer and autumn. Fertilizing should not be too frequent. Usually, it can be applied almost once a half month. When the pot soil is dry, do not apply fertilizer if the soil is too wet. Fertilizer application in summer should be paid attention to, and fertilizer control should be paid attention to, and the time selection should be appropriate. It should be carried out in the morning or at night, and no fertilizer should be applied at noon. Generally, fertilizer should be stopped in winter, because it grows very slowly, and the fertilizer applied before winter can meet its needs

2、 What about excessive fertilization

If the fertilizer is mixed with water, a large amount of watering can be used. Clean water can wash the soil in the basin and dilute it to excess fertilizer. If the fertilizer is buried shallow on the soil surface, it can be dug out and the fertilizer can be removed directly. If the soil and fertilizer are much separated, it will be replaced with new soil

If the root system is damaged due to excessive fertilization, the rotten root system should also be trimmed, and it should be strictly disinfected and dried. Finally, water the pot and wait for it to slow the seedling. During the slow seedling period, it can not be exposed to the sun

3、 How to control the amount of fertilizer

When applying fertilizer to the plant, the principle of thin fertilizer and frequent application should be taken as the amount of fertilizer, so that the plant will not be hurt. Heavy fertilizer can be applied when buds appear, and the proportion of dilution should be increased during seedling fertilization
