It's time to
Prepare irrigation systems for spring watering demands. Flush the lines clear, check and repair any leaks and replace any outlets, which aren’t working properly.
In the Subtropical Garden
Plan areas for future tree planting to provide shelter from cool, dry August winds that can be damaging to the garden.
Pimple Psyllid on Lilly Pilly
Lilly pillys are very susceptible to an insect called Pimple Psyllid. It appears on the new spring leaf growth.
They appear on Lilly Lilly, eucalypts, and wattles with new growth attacked first often turning leaves and shoots bright red but becoming distorted and twisted as the insect increases numbers. Leaves are covered in blisters. Black sooty mould fungus often follows growing on the honeydew exudate from the insect.

Firstly, only ever select Lilly pillys that are resistant to psyllid attack. These include the Acmena smithii and Syzygium austral hybrids such as S. 'Resilience', S. 'Select', S, 'Cascade', S. 'Little Lucy', S. 'Royal Flame'. A. smithii hybrids include 'Allwyns Magic', A. s. 'Cherry Surprise'.
Spray regularly with a horticultural oil like Pest Oil, Eco Oil, then place Confider tablets around base or sprinkle Richgro Bug Killa to the soil and water in. Repeat fortnightly and reapply granules every 2 months.
Westringia 'Wynyabbie Gem' and W. 'Moonlight'
A great native shrub of coastal origin but suited to areas in drought or frost prone as this shrub is very hardy. Variegated leaves adds to its lightness in colour in the garden and the mauve blue flowers all year round adds to its charm. In tubs, rockeries, massed planting , informal groupings of clipped into a formal low hedge, this Variegated Coastal Rosemary is an excellent form of westringia.

Double Lavender 'Lavish Rose'
Stunning and new, the world's first double lavenders called 'Lavish' have just arrived for spring release. Each variety has multi-double petals or flower wings creating a much larger head of gorgeous sweet-smelling flowers.
The result of 15 years research by Bob Cherry and John Robb at Paradise Nursery, the Lavish lavenders are a real breakthrough in breeding.
Flowers are perfumed, and found up and down the stem not just at the top as with normal lavenders. Growth is 0.5m tall and wide. Best in well drained soils in full sun. Look for several different colours.
