I have to say that I'm thrilled to bits about these kohlrabis which I picked today. They are huge and very heavy. I just hope that they're not tough. I'm going to make a kohlrabi and potato soup with them.
I have replanted the aubergine in their place, as it just wasn't getting enough sun back next to the beef steak tomato. Where the aubergine was, I have sown some more bush beans.

Have discovered that I probably put down too much horse manure (excess nitrogen) last autumn than was good for onions. None of my onions look too good - in fact, all they've done is to grow upwards, rather than outwards in the bulb. So I've used them for salads as in spring onions and have sown radishes there instead.
Kohlrabi obviously likes horse manure, but onions don't. Not too much anyway.

The other disappointing thing is the carrots. I only have one square of them , but it's possible that the soil isn't clayey enough for the rather short, rounded carrots which I sowed. They are taking forever. Apparently only the long ones like loose, friable soil. I thought that the SF bed wouldn't be deep enough for long ones. So we live and learn. Never mind - I can buy both carrots and onions from the local farm.
