Bougainvillea is a hardy tropical vine that grows in areas where winter temperatures remain above 30 degrees F. (-1 C.). The plant usually produces three rounds of vibrant blooms in spring, summer, and autumn. Bougainvillea needs at least 6 hours of full sun a day to flower profusely and look its best. This plant loves the heat too. Not enough sun = not enough color. Water a newly planted bougainvillea frequently to keep the soil moist. Once the plant is established, it blooms best if the soil is a little on the dry side. Water the plant until liquid drips through the drainage hole, then don’t water again until the potting mixture feels slightly dry. However, don’t allow the soil to become completely dry because a water-stressed plant won’t bloom. Water the plant immediately if it looks wilted. Bougainvillea is a heavy feeder and requires regular fertilization to produce blooms throughout the growing season. You can use a water-soluble fertilizer mixed at half strength every seven to 14 days, or apply a slow-release fertilizer in spring and midsummer.
Watering:
During summer, Water daily or when the soil starts to become slightly dry at the top. During Winter season water once in 2 days or when the soil starts to become slightly dry at the top. Keep the soil lightly moist at all times, but do not overwater as this will cause brown spots and leaf drop. Curly or dry leaves suggest, the plant is dry and needs watering. Water in the early morning or late evening when temperatures are cooler. Always check your soil before watering.
