Bougainvillea is not your typical houseplant—in its natural state, it's a sprawling climber and shrub with formidable thorns, often found on the exterior of buildings (like climbing up a trellis or over a fence) or in gardens in subtropical-to-tropical climates. Best planted in the spring, bougainvillea is a quick grower, often adding more than 36 inches in length per year. Winterizing a bougainvillea also includes watering practices and suspension of fertilizer. NO feeding should take place until late winter or very early spring. Container plants can accumulate salts from fertilizer, so it is wise to flush the container a few days after feeding the plant to prevent root burn. You may also choose to simply top dress the container with well-rotted manure or compost. Situate the containers in a cool area but one that doesn’t freeze. Often, the garage or basement is ideal, but make sure the plant has exposure to sunlight. Part of the care for bougainvillea plants over winter is to keep them a touch on the dry side.
