    Does anyone grow anything to help get rid of aphids or do you just use sprays and kill them???

    Having lots of flowers helps attract hover flies and predatory wasps which then help control aphids. Don't spray them here and leave it to the ladybirds and others to reduce the numbers in the garden. Seen good numbers of ladybird larvae and some solitary wasps about already this year but only the odd mature ladybird. Have some aphids on my sweet peppers which are indoors and are not accessible for the friendly bugs to eat them so taking some time to squash them when I notice them.
    Happy gardening!

      In the greenhouse I use an organic soap spray if necessary. Outside I don't use anything relying on predators to sort things out takes a week or two sometimes. If I think they might become a problem I use the hose to blast them off when watering usually French and runner beans. Blackfly on broad beans I pinch the top couple of inches off. On roses and lupins I squash with fingers, especially the dread lupin aphid.

        We tried a few home made remedies ourselves.

        First was a really, REALLY strong black tea. We brewed it specifically for this reason, let it cool and then sprayed it onto the leaves.
        Within a day there was a giant aphid party. It looked like a Techno-Rave and they multiplied like crazy. Another two days later almost all of them disappeared so I guess the hangover killed them.... Success in that regard.

        My mother in law swears on another remedy to kill them off. She collects wild growing stinging nettles and (giant) hogweed (please wear gloves while doing so), puts them into a water filled bucket with a lid on it and lets them rot for about 1-2 weeks in warm weather. The resulting mixture can be sprayed onto the plants. The nettles provide nutrients whereas the hogweed kills "all them nasty critters".

          Yes; the overwintering freesias are prone to them in spring time, also found them on the young shoots of the pitcher plants.
          From the aphids point of view: they've got shelter from the weather, from predators and a supply of food, nice easy life for them.
