How to grow best bougainvilleas in Australia #aboutthegarden.ind
The popularity of bougainvilleas in Australian gardens comes as little surprise. These hardy climbers will bring dazzling colour to your garden throughout the year, even in the face of severe neglect or drought. Bougainvilleas are also versatile. Traditionally a climber, bougainvilleas can be trained to behave like shrubs, trees – even hedges. Bougainvilleas also make spectacular hanging basket and pot specimens.

Bougainvilleas are available in all the warmer shades of the spectrum like red, pink, orange, white, gold, yellow and warm purple. There are also varieties with variegated foliage, so carefully choose your bougainvilleas to suit the look and colour scheme that you want.

‘Bambino’ bougainvilleas – compact forms of bougainvilleas

Bambino bougs are a collection of new bougainvillea selected for their smaller growth habit and superior flowering. Bambino Bougs come in a range of vibrant colours and varieties suitable for enhancing pot plants, courtyards, patios, balconies, hanging baskets and mass planting. A rewarding low maintenance plant for a well drained soil in a sunny position.

Bougainvillea shrubs in the garden

It is easy to train a bougainvillea to become a shrub and they are very forgiving of the beginner with the pruning shears. Make a mistake and they will quickly recover enough to give you a second chance. Dig 5 IN 1® Organic Plant Food into the soil before planting and fertilise every 6 months with Searles Hibiscus & Bougainvillea Food for best results. Prune off runaway branches as it grows, so that the bush maintains a compact, round shape. Once the bush stands between 100 and 150cm tall, prune off the branches on the lower 50cm of the bush. Cut right up against the trunk. This should achieve a pleasing, ‘lolly-pop’ shape. Continue to prune when needed. To make the most of flowering, stop pruning when flowers start to appear and begin again when flowering has finished. To boost flowering, fertilise fortnightly with Searles Flourish Soluble Plant Food.

Bougainvilleas in hanging baskets 

Choose bougainvilleas that are not too advanced for growing in hanging baskets — Bambino varieties are ideal. Use large hanging baskets at least 50cm wide, as smaller baskets will dry out too quickly in hot weather. Use a high quality potting mix such as Searles Peat 80 Premium Potting Mix and make sure the original soil level of the pot does not fall below the new soil level in the basket, once planted. Once your bougainvillea hanging baskets are watered they will become quite heavy, so pot them up and hang them before applying water. Hang the basket in full sun and rotate the basket every two or three weeks for even flowering.

Bougainvillea as trees

Bougainvilleas can make wonderful shade trees and the method for creating one is similar as for the shrub. Prune off the lower branches when the bush is 150cm tall, but allow the upper branches to spread further to form a canopy as time passes. Regular, light pruning is the key to a successful result, so keep a regular eye on its progress. Gradually prune more lower branches as the tree develops to create a shaded area beneath the tree, high enough for an adult person to stand beneath it. Yours will be the only tree in your neighbourhood that flowers with such ease or vigour!
