Bougainvillea Single Head Multicolor
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.
Typically, you will see the best display of blooms following a dry winter. If you are using bougainvillea as an indoor houseplant, make sure to keep the plants mostly dry during winter months.
Height: Up to 15 ft (4.5 m) if not pruned back. Can be grown as a bonsai -- bougainvillea bonsai tree can be kept small with frequent pruning.
Light: Full sun. Give it at least 4 hours of direct sun each day. Bougies won't bloom without enough light.
Water: Water thoroughly, then allow the top 2 inches (5 cm) of soil to dry out between waterings. Empty drainage tray to prevent soggy soil, which can lead to root rot. Overwatering will cause leaves to turn yellow and fall off. Plant bougainvillea in a pot with drainage holes. Keep slightly drier in winter.
Humidity: This South American native likes high humidity during the growing season, spring through fall. Aim for 50% relative humidity around the plant. It's a good idea to use a cool-mist room humidifier.
Temperature: Average to warm temperatures 60-80°F/16-27°C. Bougainvillea plants are frost-tender. Unless you live in a climate that's warm year-round, bring your plant back inside when the temperature dips below 60°F at night. It doesn't like the cold at all.
Soil: Good-quality, all-purpose potting mix.
Fertilizer: Feed every 2 weeks spring through fall. I highly recommend using fertilizer specially made for bougainvilleas.
Propagation: Take 4 in (10 cm) stem tip cuttings in spring and root them in moist soil. Propagating the cuttings requires a heat mat for best results. Cuttings should root in about 2 months.
