Positives of Proteas

Sophie visits a flower farm and nursery that is dedicated to growing the colourful and dramatic South African Proteacea. Siblings Tina Bolton and Richard Gibson took over the family business when their parents retired. What their parents thought might be a bit of a hobby turned into a 7-day-a-week occupation. The farm grows Leucadendrons, Leucospermum and Proteas which all grow well in the area as it has a similar climate to Cape Town and the nutrient-poor, acidic soil suits them perfectly.

Richard says he loves the colour of the plants. Tina runs the cut-flower side of the business; with their wide range of species, there is something in flower all year around. Proteas alone flower for about 6 months a year. Plants are irrigated for the first three years and then they are left to themselves. They like good drainage and full sun. They can be grown in pots, using native plant potting mix.

Pruning is important to create a bushy form; this is best done by cutting flowers for indoors.

Gardening Australia presenters answer commonly asked gardening questions.

Flushing Drip Irrigation

Josh Byrne explains why it’s important to flush a drip irrigation system. Drip irrigation works by providing small, measured amounts of water near the plant’s roots, where it’s most needed. Irrigation pipes can get clogged with material from the water supply or a break in the system, so it’s a good idea to have a flush point to clear this out.

On Josh’s vegetable patch, he puts a flush valve on the end of each line, but in other sections, such as a shrub bed that is more permanent, all the lines are attached to a single flush point so he can clean out the whole system at once. Josh does this once a year on most of his lines, but suggests doing it more often if you live in an area with poor water quality.
