So we appear to be the only plot on the allotment -not- to have blight, either on potatoes or tomatoes ... however, even worse! - it's in our greenhouse. *sob*
Looking like we may lose a significant amount of greenhouse2 (in our neighbour's garden, usually the most productive one cos it gets more sun, although this is our first year with Nick's "greenhouse on legs", which he was hoping would bring more sun in - and so far, we've had ripe tomatoes first in there, which is boding well ... although to be fair, we did plant in there first!)
So. Time will tell, but right now it looks like we're going to lose 1 plant (will check the variety and report back!) and a lot more have it on the leaves, which Nick is cutting back.
