1. When Bougainvillea spectabilis is still a small seedling, its branches are still very sparse, and the plant type is also very small, at this time, nitrogen fertilizer needs to be applied 1-2 times to promote the growth of branches and leaves.After that, some compound fertilizer can be applied to make the branches of the plant more robust.
2. For mature Bougainvillea spectabilis, the main way is to apply balanced compound fertilizer of nitrogen, phosphorus and potassium, which can provide nutrients for plant flowering.Usually, after the new buds grow out of the new leaves, the main application of phosphorus and potassium fertilizer can promote flower bud differentiation and help the plant blossom better.When it becomes a plant, do not apply a large amount of nitrogen fertilizer, otherwise it will not blossom.
When fertilizing Bougainvillea spectabilis, you can bury the fertilizer in the potting soil, or dilute it with water, and then pour it along the edge of the pot.Fertilization can use farmyard manure, compound fertilizer, can also use organic fertilizer after retting, no matter what kind of fertilizer is used, can not make the concentration of fertilizer too high.And when the temperature is too low or too high, we should stop fertilizing first.
If you accidentally fertilize too much, you can take out the fertilizer from the soil.But if it is watered after dilution, it can be diluted by pouring water.Of course, if the situation is more serious, it is necessary to remove pots and soil, and if there are rotten roots, it is also necessary to carry out reasonable pruning.
