Hmm, I actually fed them a couple of weeks ago (Ooh, maybe it's that?), and they've not had much tap water at all. Odd. I've googled and it mostly suggests 'stress'. Well, I am stressed now. I want my plants to thrive! I could try giving them another feed, or maybe feeding 1 and seeing what happens to the others (3 bushes, 2 varieties). They've still kept their flowers on, which is good I think. But they'll need to keep some leaves.
Rooster I love that people are talking about running put of space and you've filled your greenhouse with catbeds+cats. i don't have a greenhouse, but if I did, I'd have cats in there. My cats are getting on a bit now, 1 prefers to stay inside but the other follows me about like a lamb, and loves it outside. But he has been very good this year, and not sat on, knocked over or eaten any plants. Progress.
Ooh, I bought a cherry tree earlier, a Lidl's special. I'd wanted an eating cherry (tthe pic suggested they'd have a Stella ), but there was only sour cherry so I bought that. Had better check it's self fertile...
