Can someone tell me. where aphids actually come from. And how they get there. I had an almost totally aphid free garden, until the carpet roses started to flower and suddenly they are infested. One fc rose that has not yet started to flower has no aphids on it.
I'm VERY curious about this.
Last year I bought some fabulous calibrachoas, and a week later they were covered in aphids. Huge ones. Did they come from the nursery, were they incubating as I bought the plants. Spraying was no good, it ruined all the flowers, and they seemed to be almost entirely on the flowers. Never again in my garden, BUT! have those little beasties been hibernating until now, and how would they find the roses that are about 50 metres from where the calibrachoas were.
The infected plants were disposed of in the rubbish, not the compost (which we don't have space for anyway)

I would say that total permanent eradication of aphids is impossible. They are a part of the lifecycle of the earth. They are controllable though. This article does give plenty of info about them https://greenmethods.com/aphids/

Best method always is to feed and feed some more, looking after the soil is most of the answer

Mother nature gives them to you so you can never quite relax in your garden

Aphids are among the most destructive insect pests on cultivated plants in temperate regions. They are capable of extremely rapid increase in numbers by asexual reproduction. About 4,400 species are known, all included in the family Aphididae.
Aphids are distributed worldwide, but are most common in temperate zones.
They can migrate great distances, mainly through passive dispersal by riding on winds.
More on wiki, if you want to see how successful they are. I don't really worry, my roses always have them, they haven't killed a rose bush yet, haven't even affected the flowers really.

I think ants muster them and herd them onto good feed, the same way we do our stock.

from the RNZIH Aphids can also be lured away from your crops by placing a yellow bowl half filled with water amongst your veggies. Aphids, being attracted to yellow, will land on the water and drown. Alternatively, cut some yellow card, smear with petroleum jelly, attach to a stick and plant amongst your veggies.
I have done the yellow card trick but I hadn't heard of the yellow bowl with water. Will have to give it a try next time I need to eradicate aphids.

Well I had to laugh at that explanation, and must say, there are quite a few ants on the rosebushes at the moment, but living almost at the seaside, we expect to have a lot of the little blighters

Now that you mention it, I HAVE heard of smearing vaseline on cardboard for some sort of bug control, but didn't know the card had to be yellow, and didn't remember that it was for aphids. That seems like a fairly easy thing to do, and if I'd asked on here last year when they were on the calibrachoas, I may have still been growing them Just to add to my problems, the flower carpet roses are a golden colour, so no wonder the aphids are making a home amongst the foliage and on the flower tips.

Please explain more, about how feeding the soil helps control aphids? Thanks.

I thought that was white fly.

Well, it seems sensible when you consider ants farm aphids to produce the sticky sugars that also foster sooty mold. And I don't know about your garden, but it seems to me where there are aphids, there are ants.
And I just sprayed my mini rose with Bugtrol - because of the aphids. Fingers' crossed! Glooby stuff, never used it before, so we'll see.
