that the raspberry leaves looked similar but not as bad.

So I went to the chemist for Epsom Salts ("It's not for me, it's for may
tomatoes!") and did a foliar spray.

Question: I'd much rather sort my soil out - how? It's naturally
alkaline and sandy and was previously a bramble infested lawn.

Dolomite is a slow release magnesium source, but it also makes soil even
more alkaline.

(Anyway growing tomatoes in the same soil two years running is asking fro
trouble)

Urglers,

There's a band of dolomite running from the Durham coast to Nottingham - as
I said once before, but where can I buy dolomite grit?
