Hi OH, me and woolly undies don't get on, as a child I was sickly fequent pneumonia and Mum tried that but as I said to her, they fidget me! Still can't wear wool next to my skin!
Most of my fruit trees have been in at least a couple of years, so they might benefit from a wool mulch ? I just moved the mulch to put in some carrot seed and fill a few gaps, there were lots of tiny worms right on the surface.
I have gherkins cabbage, kale, flowers leaks and beans all in the same bed, and now carrots, hopfully that will fool any pests, diversity seems to lower the risk of pests, where a large block of anything seems like an invite to a feast.

I planted some red cabbage which are not supposed to attract the cabbage butterflies, so far so good, they are already more than 2ft accross look very healthy and are starting to heart up.
