1, base fertilizer: whether it is potted breeding Bougainvillea, or ground cultivation breeding, planting time should be in the soil to add enough base fertilizer.In general, bone meal, chicken manure or eggshell can be used, do not use chemical fertilizer, easy to burn roots.
2. Top dressing: When applying fertilizer, do not apply the fertilizer to the root system. Dilute the fertilizer with water and apply it along the edge of the flowerpot.If it is too close to its roots, it will burn its roots.
It needs regular topdressing during its vigorous growth period, usually once every 7-10 days.In spring and early summer, we should do a good job of fertilizing.In autumn, it is usually necessary to control fertilization slightly, which can be applied once a half month or so.In winter, it will grow very slowly, but the appropriate application of compound fertilizer can help it survive the winter.Fertilization should be carried out when the pot soil is dry, when the temperature is too high, fertilization can not be avoided, especially when the sun is strong at noon.
In the growth period, nitrogen fertilizer is mainly applied, and before the flowering period, phosphorus and potassium fertilizer is mainly applied, which helps it blossom more.It is better to apply natural fertilizers for maintenance at ordinary times, such as fruit peel fertilizer, beer water, rice washing water, or organic fertilizer after decomposition.If chemical fertilizers are to be applied, attention should be paid to the method of fertilization, not close to the root system of the plant.
