How to Grow Bougainvillea
Step-by-Step Process (Recommended for Home Gardeners):
- Choosing the Right Spot: Bougainvillea loves full sun and should be planted in an area that receives at least 6 hours of direct sunlight daily. It’s best grown outdoors, but you can plant it in large pots for balconies or terraces.
- Soil Preparation: This plant thrives in well-drained, slightly acidic soil. You can mix some perlite or coarse sand with the soil to improve drainage. A quick home gardening tip is to add crushed eggshells or banana peels to the soil, which provides calcium and potassium, essential for strong root growth and flowering.
- Planting: If planting in the ground, dig a hole twice as wide as the plant's root ball. For pots, make sure the pot has drainage holes at the bottom. Add gravel or broken terracotta pieces to improve drainage. Bougainvillea doesn’t like to sit in water, so it’s important to avoid waterlogged soil.
- Watering: Bougainvillea prefers dry conditions. Water deeply but infrequently. Wait until the top 2 inches of soil are dry before watering again. Overwatering can lead to root rot. A simple home trick is to use a watermatic stake in the pot for easy, automated watering.
- Pruning & Training: Bougainvillea needs regular pruning to maintain its shape and encourage new growth. Prune after flowering to remove dead or weak branches. If you're growing Bougainvillea on a trellis or fence, gently tie new growth to the structure to train it in the desired direction.
- Fertilization: Bougainvillea doesn’t need heavy feeding. A balanced, slow-release fertilizer applied in spring will support growth. Homemade compost mixed with the soil, like onion peels, can provide slow-release nutrients. For extra flowering, use a fertilizer with a higher phosphorus content.
Common Problems, Pests, & Diseases
Urban Farmer’s Solutions for a Healthy plant:
-
Leaf Drop: Overwatering or sudden changes in temperature. Ensure proper drainage and avoid excessive watering.
-
Aphids and Whiteflies: These pests feed on the sap of Bougainvillea, causing leaf yellowing. Spray with a neem oil solution 2 ml/20drops per liter of water every 10 days. Neem oil is natural and safe for plants.
-
Leaf Spot: Leaf spot can form in humid conditions, showing up as a white-Brown spots on leaves. Improve air circulation by spacing the plants or pruning regularly. Use an organic fungicide like Tricho Shield 5 gm/one spoon per liter of water. Spray every 20 days for effective control.
-
Root Rot: Caused by overwatering or poor drainage. Ensure proper soil drainage and use a perlite or sand mix for potted plants to promote airflow in the soil. To prevent or cure, mix 5 gm/one spoon of organic fungicide Tricho Shield per liter of water and drench 50 ml of the solution near the plant's stem.
-
Leaf Eating Caterpillars: The bougainvillea caterpillar is a green or brown caterpillar that is roughly 1″ long. The larva mimics stems and branches very well. It mostly feeds at night, so you might notice the damage without seeing the insect. Spray with a neem oil solution 2 ml/20 drops per liter of water every 10 days.
Best Practices for Growing Bougainvillea
Urban Farmer’s Expert Tips for Bougainvillea:
-
Sunlight Needs:
- Bougainvillea requires full sun to produce abundant flowers. Ensure it's placed in an area with 6-8 hours of sunlight. If grown indoors or on terraces, move the pot around for sunlight exposure.
-
Pruning for Strong Growth:
- Prune regularly, especially after the blooming season. Pruning encourages the plant to become bushier and produce more flowers. Use clean, sharp pruning shears to prevent disease transmission.
-
Avoid Overwatering:
- Bougainvillea thrives on minimal water. Ensure the soil dries out completely between watering. Using mulch made of gravel around the base of the plant helps to retain heat and reduce moisture retention, especially during the rainy season.
-
Proper Support:
- Bougainvillea is a climber and requires support. Train the plant by gently tying it to a trellis or fence with soft ties to prevent damage to the branches.
