How to Increase Flowering in Bougainvillea

Bougainvillea, with its vibrant colours and lush blooms, is a stunning addition to any garden or landscape. However, some gardeners may encounter challenges when it comes to maximising the flowering potential of this beautiful plant. If you're seeking ways to enhance the blooming process and need a year-round floral fiesta of this spectacular flowering plant, we've got you covered. Here are some expert tips to help you increase flowering in your bougainvillaea:

Make Hay While the Sun Shines

Bougainvillea thrives in full sun, so ensure that your plant receives at least 6-8 hours of direct sunlight each day. Lack of sun exposure can hinder flower production, so choose a sunny spot in your garden or patio to allow your bougainvillaea to bask in the sunshine.

Cut to the Chase & Shape

Regular pruning is key to encouraging flowering in bougainvillaea. Prune your plant in late winter or early spring, removing any dead or excessive growth. This process stimulates new growth and leads to more flower production. Additionally, consider shaping it through selective pruning, which promotes a more compact and bushier plant, resulting in an abundance of blooms.

Make Waves

While bougainvillaea is a drought-tolerant plant, it still requires regular watering for optimal flowering. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot and hinder flower development, so strike a balance to keep your bougainvillaea happy and blooming.

Power Up with Nutrients

Providing the right nutrients is essential for enhancing flowering in bougainvillaea. Use a balanced fertiliser with a higher phosphorus content, as phosphorus promotes flower production. Apply the fertiliser every 4-6 weeks during the growing season to ensure your plant has the necessary nutrients to support abundant blooms. Also, make sure you regularly inspect your plant for pests and diseases, promptly addressing any issues that may arise.

Temperature and Climate

Bougainvillea thrives in warm climates and can be sensitive to cold temperatures. If you live in a region with colder winters, consider growing your bougainvillaea in containers that can be brought indoors during the colder months. Protecting your plant from frost and extreme temperature drops will help maintain its vigour and flowering potential. Also check whether your flowering plant is getting adequate airflow and ensure proper drainage to prevent waterlogged soil, which can impede flower production.
