Welcome to my website where I gather information about plant pests and pathogens preying on gardens in my local area in Melbourne. I want to live in harmoney with nature and so I use exclusion techniques and natural predators to protect my edible and ornamental plants instead of using poisonous chemicals...................John Ashworth 27th July 2015.
Aphids are normally dormant in winter, but occasionally I will come across a cluster of them after a spell of warmer weather.
They are easy
to remove if you are vigilant and don't let them get a foothold. Just
wash them off the flower buds or new shoots they are feeding on with a
jet of water from the tap.
I have never really found them to be a nuisance because they are so easy to remove.
Why Greenfly are a Pest.
In my garden,
I usually find them on new buds on roses in early spring. If left they
will munch their way through the new buds and shoots and deform the
just rub them out when I find them with my fingers, but if there are
lots of them, I remove them with a jet of tap water. They seem unable
to regain their place on the buds and shoots of my roses and (I guess)
starve to death where they land.
I spray my roses with aerated compost tea
every month, and I am sure this increases the plants resistance to
aphids, but I still get some on the new shoots in between sprays.
