Patches of my poor little vegie garden are slowly being taken over by aphids. They got to my potted mint first, so I read on the internet that spraying them with very weaky soapy water should kill them but perhaps I mixed the soap too strong.... long story short I might be the first person ever to have killed not only one but TWO mint plants.
They've appeared on a few other plants now as well so I'm hoping not to make the same mistake twice. I'd prefer to avoid industrial pesticides if possible, but if there's a vegie-friendly option I might consider it.
Good ol' Gardening Australia to the rescue, a homemade White Oil:
How many do you have? The best natural approach is to remove them by hand. Just pop some gloves on, pull them off and drop them into a bucket of soapy water. It takes a bit of time and patience but isn't difficult.
Thanks for joining in the discussion and sharing your experience @Matty. Great to see you make your first post on Workshop. Welcome! I'm looking forward to reading about your own projects and plans soon.
I found this, on a site that I only discovered about a week ago:
I was impressed that the author mentioned composting to ensure strong plants, which makes them less attractive to pests.
A good read, & site for ideas.
Agree completely, especially about cutting the mint right back, & leaving the root system intact. It's been my experience that plants come back better than ever after a good cut back.
Ensure that you use sharp & clean secateurs, & I guarantee, you will have a bumper crop in no time. An initial watering around the plants with compost tea, Seasol, or diluted worm casting tea will help them get over the shock.
