you love the colour of purple in the garden, then
you'll just adore the magnificent flowering Tibouchina.
Tibouchina's are magnificent shrubs that are ideally
suited to our tropical to sub-tropical climate.There
are many wonderful varieties available that vary in
size & colour from 1m shrubs to 6m trees, with
deep purples & even pink flowers. There are some
varieties that flower just about all year round, but
their main flowering times are autumn and spring -
& they look fantastic!
SOIL & CLIMATE
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 using Sulphur Powder. Follow the
directions on the container to suit your soil type.
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.
Fertilise Tibouchinas every autumn & spring with 5 in 1® Organic Plant Food and also add a
couple of handfuls of Searles® Azalea & Camellia
Plant Food. Then cover the soil with a thick layer
of a high quality mulch, such as Searles® Premium Garden Mulch,
and then give them a good deep watering.
When first planting a Tibouchina, they will need regular
watering until established, to ensure a good start
to their life. Once they have established a good deep
root system (after the first year), a good deep watering
once a week should suffice. If you live in an area
that receives a moderate to high rainfall, you may
very well find that these beautiful shrubs will hardly
need any additional watering at all.
The real trick to promote profuse flowering for the
next season is to prune them back hard immediately
once the last flowers fall. This will encourage more
new growth, helps to keep the foliage compact and
results in more flowers.
Tibouchinas is good fun and they require very little
maintenance. They are an easy to grow plant, and
when in flower, they are just stunning, decorating
the garden with a lovely and profuse display of
deep purple blooms.
Happy Gardening with Searles from the Searle family.
