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 for Pots
Several bougainvillea varieties are suitable for growing in containers.
- “Miss Alice” is a shrubby, easily pruned variety with white blooms.
- “Bambino Baby Sophia,” which provides orange blooms, tops out at about 5 feet (1.5 m.).
- If you like pink, consider “Rosenka” or “Singapore Pink,” which you can prune to maintain container size.
- Red varieties suitable for container growing include “La Jolla” or “Crimson Jewel.” “Oo-La-La,” with magenta-red blooms, is a dwarf variety that reaches heights of 18 inches (46 cm.). “Raspberry Ice” is another variety suitable for a container or hanging basket.
- If purple is your favorite color, “Vera Deep Purple” is a good choice.
Growing Bougainvillea in Containers
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.
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.
Bougainvillea Container Care
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 7 to 14 days or apply a slow-release fertilizer in spring and midsummer.
