Garden Radio Round Up April 15 - 1615 April 2017 Sandra & Graham Ross
Our very wet start to autumn is briefly abating. It's a great opportunity to get out there and start planting.
We are planting all of our new Collectors' Plant Fair purchases in the garden this autumn and looking forward to a spring display.
What are you planting? Log on to the Garden Clinic Facebook page and tell us what's going into your garden.

It's Time To:
In the temperate zone
It's not just the perfect time to plant, it's also a great time to repot any tired outdoor (and indoor) plants, especially in pots in which the potting mix has slumped well below the rim of the container. Lift the plant out of the pot, then replant into the same or a larger container using premium quality potting mix.
Is your lawn looking a little beaten up? The recent Collectors' Plant Fair has taken a bit of a toll on the lawn at the Hawkesbury Race Club. But with a little help it will bounce back nicely.
It's time to aerate compacted lawns using the tines of a garden fork (hire an aerator for larger lawns). Apply controlled release lawn fertiliser and water in well to boost turf growth for a greener, healthy lawn over winter.
In the sub-tropics
It's time to admire the glorious slipper vine, Thunbergia mysorensis, with its cascading chains of flowers that last for months. We have one in our Sydney garden that never stops flowering
Plant so it can create a curtain from a tall pergola or wire suspended between posts.

Banksia plagiocarpa 'Hinchinbrook Banksia'
This is a magnificent and striking Banksia, well worth growing as an ornamental for its incredible blue-grey flower buds which make very impressive cut flowers. It also sports lush red new growth. Its range in the wild is limited to Hinchinbrook Island and the adjacent mainland in QLD. Grows well in the eastern states, tolerant of humid summers, and can be grown as far south as Melbourne. Needs well drained soil and tolerates light frost. It will not tolerate heavy frost, however, being from North Queensland.
Perfect to grow as a low, bushy coastal windbreak. Brings bees and nectar feeding birds to your garden. Feed with a quality native plant fetiliser like Bush Tucker from Neutrog. Prune lightly after flowering to encourage shapeliness.
Height: 4-6 m
Width: 3-4 m
Flowering time: Summer autumn winter
Soil: loamy sandy
Climate: sub- tropical, warm temp, cool temp

These pearly-white, fluffy little sap-suckers tend to attack plants under stress. Like aphids they secrete a honey-dew that black sooty mold grows on. Then in come the ants to eat it, and here is where the trouble starts. The ants can carry mealy bug from plant to plant making your small problem a big problem in no time. Mealy Bug like to hide in those protected places, like inside palm fronds. So if you see one or two its best to have a closer look. An infestation could be brewing, and it could be below the surface.
Controlling mealy bug can simply be a matter of reducing the water given to plants now the weather has cooled, scrubbing them off using natrasoap and an old toothbrush. Then spray with a mixture of Eco Oil and Eco Neem. But a severe infestation of mealy bug is a good indication that the plant is not happy, so it may also be necessary to investigate what else is wrong.
Mealy bug will eventually cause this plants leaves to drop if left untreated.
