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. If you don’t have growing space or live in a suitable climate, you can plant bougainvillea in a pot. If you live in a chilly climate, bring potted bougainvillea plants indoors before the first frost.
Bougainvillea performs well in a relatively small container where its roots are slightly restricted. When the plant is large enough for repotting, move it to a container only one size larger. Use a regular potting soil without a high level of peat moss; too much peat retains moisture and may result in root rot. Any container used for growing bougainvillea must have at least one drainage hole. Install a trellis or support at planting time; installing one later may damage the roots.
ougainvillea 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. Bougainvillea blooms on new growth. This means you can prune the plant as needed to maintain the desired size. The ideal time to trim the plant is immediately following a flush of blooms.
