How to grow bougainvillea in pots and add bold color to your container displays

Growing in pots is an ideal way to add impact to outside spaces. Whether you have a small terrace, patio or balcony, growing climbers in pots is a clever solution that can have a transformative effect. Not only are they beautiful, but floral vines can help enclose a yard, providing privacy and screening to make your space a tranquil haven.

Many popular flowering climbers can be grown in pots, including star jasmine and clematis. Bougainvillea is another impressive plant that can also be grown in containers, with tropical-looking blooms opening in bold, rich colors.

While you might know how to grow bougainvillea in the garden border, growing bougainvillea in pots requires a slightly different approach to ensure that your plant thrives to its full potential. Here, one tropical plant expert reveals how best to care for this flowering climber to ensure it blooms all summer long.

How to grow bougainvillea in pots

Bougainvillea plants are native to equatorial regions in South America, typically found growing in US hardiness zone 9 and US hardiness zone 10. Growing bougainvillea in pots, however, is a good solution if you adore this tropical climber but reside in a cooler zone. Container-grown plants can be protected during the winter months, meaning that wherever you live, you can enjoy the colorful blooms of the tropics.

How to care for bougainvillea in pots

'Bougainvilleas are superb pot plants that will add vibrant color to any yard,' says Tatiana Anderson, plant expert and co-founder of Top Tropicals. 'Select a pot that is 10 to 12 inches in diameter to begin with, and as the plant grows, you can move up to larger pots, but it is important not to over-pot small plants.'

Position your container in a sunny, sheltered spot. The more sun your plant enjoys, the more blooms it will produce. Gardeners who complain that their bougainvillea is not flowering have often positioned their climber in a shady spot, so make sure your new plant gets as much light as possible.

'Use well-draining soil, such as a cactus or succulent mix, available from Walmart. You can also mix regular potting soil with sand or perlite to improve drainage,' Tatiana adds. 'I would recommend repotting your bougainvillea every 2 to 3 years or when the plant becomes too big for its container. Choose a pot only slightly larger than the current one, as bougainvilleas prefer to be somewhat root-bound.

'Through the warmer months, be sure to monitor your bougainvillea as it will require frequent watering when the temperatures rise,' Tatiana says. 'Water thoroughly when the top inch of soil is dry, but ensure that your pot has drainage holes to prevent waterlogging.'

It is also important to fertilize bougainvillea during the growing season which will improve soil health and replenish nutrients in the pot. 'Feed with a balanced, water-soluble fertilizer every 4 to 6 weeks during the growing season,' Tatiana adds, 'but reduce feeding in fall and winter when growth slows.' Bougainvillea fertilizer is available from Walmart.

Finally, when considering how to grow bougainvillea in pots, it is important to train your climber so that it grows where you want it to grow. There are many different climbing plant support ideas to pick from, but whether you opt for a trellis, wires, or a hazel structure, be sure to tie in new shoots and train your plant upwards. Garden twine is available from Walmart.

FAQs

How should I protect bougainvillea plants that are grown in pots during the winter?

In cooler US hardiness zones, such as zones 4 and 5, it is a good idea to protect your plants during the frosty and cold winter months. If you can, move your container to a greenhouse or potting shed from November to April, to protect your plant from the cold weather. If this is not possible, consider using horticultural fleece to cover your plant, which reduces the risk posed by snow and frost.
