Gardeners caring for bougainvillea in the garden don't need to worry much about water once the plants mature. Irrigate only when the plants start to wilt and the soil is dry. The vines do need food. Fertilize your bougainvillea every month in spring and early summer. You'll want to use a balanced, all-purpose fertilizer at half the normal dosage. Pruning is part of the work if you are caring for bougainvillea in the garden. Keep your eye out for dead wood and remove it as it appears. Save severe cut backs for a time after the bougainvillea has flowered. You can prune late in fall or very early in spring.
- Light Needs: Full sun or Partial Sun
- Watering Needs: Medium amount of water, but needs plenty of water while in bloom.
Bougainvillea are thorny, evergreen summer bloomers, but their orange, yellow, crimson or purple flowers are actually modified leaves called bracts. The bracts surround the actual flowers that are tiny and white. To start growing bougainvillea in gardens, you'll need to live somewhere warm; otherwise, container growing of bougainvillea is recommended.
