Great bougainvillea (Bougainvillea spectabilis)

When watering Bougainvillea spectabilis, apply about 500 milliliters each time. Ensure the water penetrates deeply to encourage the roots to grow downward, avoiding shallow watering that leads to weak, surface-level root systems. Water should fully moisten the soil but not leave it soaking wet.

Bougainvillea spectabilis ideally needs full sun to partial sun exposure. Proper sunlight aids in vigorous growth, vibrant colors, and resilience against pests.

Bougainvillea spectabilis thrives in a warm environment, ideally between 65°F and 85°F. This tropical plant requires a consistently warm climate to grow and flower abundantly. Cooler temperatures can slow its growth significantly.

Bougainvillea spectabilis thrives in well-draining soil that prevents waterlogging. Proper drainage mitigates root rot risk, enabling roots to access oxygen efficiently, supporting optimal plant growth and vibrant blooms. A nutrient-rich soil enhances the growth of Bougainvillea, providing essential elements like nitrogen, phosphorus, and potassium. These nutrients contribute to robust foliage, sturdy stems, and abundant flowering. Bougainvillea requires soil with low salinity to prevent salt stress. High salt levels can lead to leaf burn and reduced growth, so maintaining suitable salinity ensures healthy, flourishing plants.

For Bougainvillea spectabilis, it's important to provide just enough nutrients to encourage blooming without overwhelming the plant. Use a balanced 10-10-10 liquid fertilizer, diluted to half strength, to avoid nutrient burn, and apply it evenly to the soil around the base of the plant.

Begin by inspecting your Bougainvillea spectabilis for any dead, diseased, or damaged branches. Use clean, sharp pruning shears to remove these branches, cutting close to the main stem. This helps prevent disease spread and encourages healthy new growth. Prune back the branches to shape your bougainvillea into the desired form. Aim for a balanced shape with an open center that allows light and air to penetrate, which promotes healthy flowering and reduces the risk of fungal infections. Thinning out the inner growth can improve air circulation and sunlight penetration. Remove any crossing branches or ones that grow inwards towards the plant's center. This practice helps maintain the plant's health and increases flower production. Regularly trim back the plant to control its overall size and prevent it from becoming too leggy. Bougainvillea grows vigorously, so check its size monthly to keep it within your desired dimensions.
