One home-grown crop I've been enjoying for several weeks is lettuce, although I did buy the initial 8 Little Gem plants as seedlings.
In fact, this photo taken at the end of April shows just one lettuce missing. There is only one left in that tub now, although I have planted four more Little Gem type seedlings I raised myself. The copper-felt mat underneath does seem to deter slugs and snails so long as I don't let the grass get too long, or the lettuce leaves don't hang down. I'm also trying rooibos tea leaves as an added deterrent.
All these have now gone, too, and have been replaced by Romana type seedlings, which I also grew myself. Thankfully it was only the outer leaves that had holes in, and the chickens didn't care, they loved those, while we ate the nice bits inside. However, it does mean I need a copper mat or something to stop the slugs and snails climbing up as the wool alone doesn 't stop them, especially once the lettuces cover it over.
I'm currently working my way through these butter-head lettuces, which have got quite big now, so just the thinnings provide a lot of lettuce. I'm leaving a few to heart up, hopefully.
