Planting Tibouchinas
Now there are a few tricks for abundant flowering. Firstly, they need a good sunny position and like to be planted into a rich acidic soil. They don't like alkaline soils (those soils with a pH of 7 or above), but flourish in slightly acidic soils with a pH of around 5.5 to 6.5. If your soil is alkaline, the pH can be lowered by adding to the soil Sulphur Powder. Follow the directions on the container to suit your soil type. Alternatively you can plant straight into Azalea, Camellia & Gardenia Specialty Mix for both gardens and pots.
Tibouchinas like a warm to hot climate and don't mind some cool weather in winter, but they will be affected by frosts, so may not be suitable for those gardens that are frosted.
