In the subtropical garden
Admire little kurrajong, Brachychiton bidwillii, below. This small, elegant tree makes a great winter show. Flowers may be pink, red or orange and size and form may vary depending on provenance. Trees look stunning when planted in informal groves.

Diseases of oak leaves
When the leaves of large trees like eucalypts, conifers or oaks become infested with disease it's often impossible to spray or treat the tree effectively.
This old English Oak is suffering from oak leaf miner, an insect and a fungal disease, anthracnose, caused by the fungus Apiognomonia.
The leaf miner tunnels into leaf leaving a blister which inevitably bursts and can cause sticky sap to drop onto pavement, plants or your car below. The latter can be a nightmare to remove.
When sap drops onto plants it often results in black sooty mould fungus occurring.
The weakened tree and foliage most likely attracts the secondary disease, anthracnose, to occur.
There's little you can do with large trees apart from raking up fallen leaves and 'hot' composting them or alternatively place in the garbage bin.
Keeping trees free of vehicular traffic on the root zone, feeding in spring and keeping the tree vigorous and healthy is the best preventative measure.
Coastal Rosemary, Westringia dampieri
A small and dense growing shrub with attractive silvery foliage, native to coastal Western Australia. It naturally grows on limestone cliffs, so it suits very alkaline soils. A very hardy and low water use plant to a metre and a half high, it is great for low maintenance landscaping. Withstands salt laden winds. It has pink buds and white to mauve flowers. A good formal or informal low hedge plant and great for coastal gardens.

Romance in the Air for Powerful Owls
The famous Powerful owls in Byles Creek valley in the north western suburbs of Sydney have continued their family growth.
Now another generation has appeared and even more owlets on the way.
This time its Sheba and Fishcake that have mated. Sheba is on the nest and Fishcake is outside keeping guard. The egg/s should hatch in around 2-3 weeks, so by mid-July we should be hearing the trilling of another chick. Local experts, watching from below, are quietly confident there maybe twins again as late last year.
