Why Won't My Bougainvillea Bloom?

Bougainvillea vines can put on a stunning show, so it’s no surprise that many Floridians try to grow them. But what happens if your bougainvillea won’t bloom?

Sun is a critical part of the equation. The more sun your vine gets, the more blooms it will put out. Without some direct sun, it just won’t flower.

Water is another key factor. Bougainvillea is native to arid climates, so check that your irrigation system isn’t applying more water than the plant needs.

If you’re pruning too often, you could be cutting off new blooms as well. Finally, go easy on the fertilizer. Too much nitrogen will encourage your plant to produce leaves instead of blooms.

So try neglecting your bougainvillea instead of babying it. You should be rewarded with beautiful blooms!
