What fertilizer should be used for the base fertilizer of bougainvillea, and what fertilizer should be used for the flowering of bougainvillea

1. What fertilizer should be used as base fertilizer?

If the soil fertility of the bougainvillea is very high, then there is no need to apply base fertilizer to it. But if the fertility of its flower soil is average, it is best to add some base fertilizer to its flower soil before potting it. This can significantly improve the fertility of the flower soil, allowing it to provide more nutrients for the growth and flowering of the plants.

There are many choices for base fertilizer, such as compound slow-release fertilizer, livestock manure fertilizer, and even homemade fertilizer made from rice water and fruit peels. However, because the slow-release fertilizer releases its effect over a relatively long period of time and can continuously increase the fertility of the flower soil, it is recommended to apply it.

2. What fertilizer to use for flowering

Because fertilizing during flowering may shorten the flowering period, it is best not to fertilize during flowering for bougainvillea varieties with a shorter flowering period. However, varieties with longer flowering periods consume a lot of nutrients when flowering, so appropriate fertilization is needed to replenish nutrients and help the later flowers continue to bloom. Choose flower fertilizer with high phosphorus and potassium content, usually it can be applied once every 15 days or so.
