Growing Conditions That Bougainvillea Loves
Sunlight: At least 6 hours of full sun daily
Soil: Well-draining mix with compost or peat moss
Water: Allow topsoil to dry between deep waterings
Humidity: Mildly humid climates preferred, but drought-tolerant once established
Zones: USDA 9+ but totally manageable in cooler climates with overwintering care
For UK gardens, a south-facing patio or sunny conservatory is ideal.
How to Plant Bougainvillea (Garden Beds or Containers)
In the Ground
Pick a sunny spot with good drainage
Amend soil with compost or peat
Space plants ~12 inches apart for airflow

Watering, Feeding & Pruning Tips
Watering
Let soil dry out between watering
Water deeply don’t mist or overdo it
Less water in winter = more blooms in spring
Fertilizing
Use a low-nitrogen, high-phosphorus fertilizer every 3–4 weeks
Compost tea or diluted organic liquid feed works great
Avoid overfeeding too much = leaves, not flowers
Pruning
Hard prune in early spring to shape the plant
Deadhead faded blooms to encourage more flowers
Light trims mid-season keep size under control
