Hi Judy, I feed about once a fortnight with home-made comfrey feed. This year I have Sungold, Cristal, Black Russian, Suncherry premium, Legend, Ferline, Stupice, Brandywine, Tamina and Coure di bue. Already harvested a few sungold which I find are reliably the first to ripen and the last to stop cropping, so a real "good doer" as we gardeners say!
The ones in the greenhouse are all planted the border trenches (compost replaced every 2 years) and my own experiment this year is to use 8" sections of 8" diameter waste pipe as "ring culture" bottomless pots placed on top of the border soil on one side of the GH and only water the feed into the rings. On the other side they've gone straight into the soil. So far I can't see any difference, but as most toms are still green it's difficult to estimate crop sizes at the moment.
The outdoor ones in 25 up to 40cm pots are doing equally well at the moment, but are difficult to keep sufficiently watered - a really good soak once a day is just about doing it - they still wilt badly but perk-up after dark so I know all is well.
