The correct way to fertilize bougainvillea What fertilizer should be applied to make bougainvillea bloom

When fertilizing bougainvillea, you can use organic fertilizer or chemical fertilizer , as long as it can promote the flowering and growth of bougainvillea. It is recommended that you can implement a phased fertilization method. So, what kind of fertilizer is good for bougainvillea and how to fertilize it?

Flower-promoting fertilizer

Since Bougainvillea is a flowering plant , the fertilizer we must prepare is the fertilizer that promotes flowering. Generally speaking, as it grows, flower buds continue to emerge from the branches, so the fertilizer we choose should be high in phosphorus content.

If other elements are not lacking, such as Huaduoduo No. 2 , it can be used regularly. Sufficient phosphorus can ensure the differentiation of flower buds. If there is no lack of potassium, the root system will be more developed ; if there is no lack of nitrogen, its top buds can continue to grow . This is the best fertilizer for it.

Green leaf fertilizer

When the soil becomes alkaline, it cannot get iron and its roots will not grow. This will eventually make the bougainvillea stunted and all the leaves will turn yellow and fall off.

So you need to prepare some ferrous sulfate , and replenish it regularly every two months or so . You don't need to use too much, so that the soil is acidic and not lacking in iron, it will grow fast and the leaves will remain green. Remember, it is best to use some vinegar when using ferrous sulfate to ensure that it will not oxidize and can be absorbed quickly.

Soil Fertilizer

The so-called soil fertilizer means that our soil should always be fertile. If the bougainvillea is not fertilized enough or forgotten to be fertilized, the soil will become barren. When the soil is barren, there is no nutrients and it may even become hardened .

This will eventually lead to a weak root system, and we must also ensure that the potting soil contains certain nutrients. Therefore, a type of fertilizer that should be kept at home is slow-release fertilizer , which can directly prepare a balanced amount of nitrogen, phosphorus and potassium.

This kind of fertilizer has a slow effect. You only need to sprinkle 10 or 8 grains. Basically, you don't need to sprinkle fertilizer for the first half of the year. In this way, there will be a weak supply of nutrients in the soil for the bougainvillea to grow. Even if you forget to fertilize occasionally, it will not cause any problems.

Of course, if you don't want to use slow-release fertilizer, you can also use some fermented sheep manure. Sprinkle some on the surface of the potting soil regularly for one to two months, which can not only ensure the fertility of the soil, but also make the soil looser and more breathable.
