1、 When to fertilize

To fertilize potted flowers, we usually choose the time when they grow vigorously. Usually, spring and autumn are the growing season of flowers, so we may need more nutrients at this time. The weather in summer is very hot, and fertilizer can be applied appropriately, but the concentration of fertilizer must be low. Fertilizing flowers in summer is best carried out in the evening, avoiding when the sun is big, which is easy to burn its roots. In winter, if the potted plants under maintenance stop growing, fertilization should be stopped

2、 Fertilization principle

When fertilizing flowers, it should be applied a small amount and many times to avoid the use of inorganic fertilizer. The applied fertilizer should not be too close to the root system of the plant, and the fertilizer should be fully decomposed before use. Under normal circumstances, do not splash fertilizer on the leaves of flowers when applying fertilizer, which is likely to burn the leaves

3、 Precautions

1. For plants that have just been put into the basin, fertilization is generally not required, and when the basin has just been changed, it also needs to recover the plants for a period of time

2. The amount of each fertilization must be small, and a small amount of fertilizer should be applied even in the growth period. If too much fertilizer is applied, the root system of the plant cannot be absorbed, and the root system of the plant will be burned over time
