1. When to apply fertilizer

Fertilizing bougainvillea needs to be done in spring, early summer and autumn. Do not fertilize too frequently, usually once every half a month is enough. Fertilize when the soil in the pot is dry. Do not fertilize if the soil is too wet. When applying fertilizer in summer, you need to be careful and control the fertilizer. The time should also be chosen appropriately. It should be done in the morning or evening. Do not apply fertilizer at noon. Generally, it is necessary to stop applying fertilizer in winter because it grows very slowly, and the fertilizer applied before winter can meet its needs.

2. What to do if you apply too much fertilizer

If you use the fertilizer after diluting it with water, you can use the method of watering in large quantities. Clean water can rinse the soil in the pot and dilute the excess fertilizer well. If the fertilizer is buried shallowly on the soil surface, you can dig it out and remove the fertilizer directly. If the soil and fertilizer are separated a lot, you need to replace the soil with new one.

If the root system is damaged due to excessive fertilization, the rotten roots should be trimmed off and the plants should be strictly disinfected and dried. Finally, after potting, water it thoroughly and wait for it to grow slowly. It should not be exposed to direct sunlight during the growth period.

3. How to control the amount of fertilizer

When fertilizing the plants, the principle should be to apply small amounts of fertilizer frequently so as not to harm the plants. Heavy fertilizer can be applied when buds appear, and the dilution ratio should be increased when fertilizing during the seedling period.
