As we don’t have a greenhouse yet, we grew our tomatoes in hanging baskets again this year. They are one of C’s favourite snacks. So far we had loads of flowers and then loads of green (unripened) fruit but they have been remarkably slow to ripen. Then after I was away for a week up north and there was a deluge of bad weather they seemed a little, well, how should I put this, a little dead. Actually scrap that. They seemed a lot dead. Well some of them do. Now for tomatoes there are a couple of possibilities when they start to look like this. It could be a lack of nutrients of some kind (magnesium apparently is the norm), the solution for this is to give them a feed of Epsom salts. It could be die back, possibly caused by overcrowding as the foliage is quite dense. It also could be blight. Blight is the worry of vegetable gardeners (or one of the worries) as it can decimate potato and tomato crops (they are the same family). It is a type of fungus (I think) which is encouraged in wet weather, so in our particularly damp summer it has been an ever present concern.
I’ve given my tomatoes a quick feed of Epsom salts and have cut off some of the foliage and am keeping watch. We’ve had a good enough supply of fruit from it so far and the fruit are staying healthy, so I think for us it was a combination of everything (apart from blight). Hopefully we still have plenty more fruit to come.
