Today I sprayed my maincrop potatoes with Bordeaux Mixture against potato blight. So far, there's been little sign of it, but this is the time it strikes. Ted Smith (Plot 44) was telling me today that for blight to thrive it requires the Smith factor: a certain degree of humidity and a certain temperature. So far this year it hasn't had that combination. It has been incredibly dry for the last month at least, and what rain there has been seems to have passed Swindon by altogether. But that could all change overnight.
