Downy mildew is a bugger. “A disease of cool, damp seasons,” opines Dr Hessayon, my usual consultant on these matters.
Utter bollocks, sadly (though Hessayon’s rarely wrong). We’re having one of the hottest, driest summers ever – and I’ve still got mildew.
Last year we had one of the wettest summers ever, and I had the best onions I’ve ever grown. Row upon row of flawless whoppers… which stored perfectly. In fact, we’re still eating them.
My theory is that mildew is caused not by damp and cold in summer, but in early Spring. We had dream Spring weather last year, and I reaped the rewards.
Not so 2010, which is turning out to be pretty dire for vegetable growers – at least, round my way. I’ve never had such a lousy crop of almost everything.
How are you doing?
