How Much Sun Does a Bougainvillea Need?

So how much sun does a bougainvillea really need? Well, these plants are sun worshippers! They thrive on at least 5-6 hours of direct sunlight every day.

And whether you go organic or chemical, liquid feed or slow-release granules, just ensure it meets your plant’s nutrient requirements.

How Often to Fertilize Your Plant

Now that we’ve got the what, let’s tackle the when. The fertilizing schedule for bougainvilleas isn’t set in stone; it depends on factors like growth stage and season. Generally speaking though, during active growth periods (think spring and summer), you might need to play chef more often. But be careful! Overdoing it can lead to an overfed, under-blooming plant – not cool! So keep an eye out for signs of nutrient deficiency or over-fertilization risks.
