My veggie garden this year has almost made me want to cry. I mentioned before that it was terrible, well it really was. Summer was a total washout for the first month - it rained ALL the time. We never really got those lovely hot temperatures either, then again it ended with downpours of mammoth proportions. This is not good for the veggie garden at all. My pride and joys ~ the tomatoes ~ have been a disaster. We did get a lot of wee cherry ones for summer salads, but the various large tomatoes only gave me enough to make one batch of passata - woe is me!! They got blight - amazing, spectacular blight. I fought it as long as I could but it was useless.
This was the lot I picked while still green in the hopes that I could ripen them in the potting shed - by taking them off the plants I hoped that they would be blight free. They were not. I ripened enough to make a very very tiny amount of pasta sauce and that was it.
Here's a bit of info...
The early blight fungus can come from many sources. It can be in the soil, it can already be on seeds or seedlings you purchase, it can over-winter in the diseased debris of your tomato plants and it can persist in the soil or debris for at least 1 year. Although early blight can occur in any type of weather, it favors damp conditions, like frequent rain or even heavy dews. (you don't say!)
I'm going to try and burn these tomatoes. Also all the foliage - you need to pick it up off the ground and dispose of it - again I'm going to burn it.
I found that copper helped. In fact I have used an organic copper dust stuff for the last few years and I've not had any blight. Obviously this year the conditions were just too much! Sad, sad, sad.
