  • Tomato Blight, Mould or Drought Stress?

    Hey! I've got a few tomato plants (in pots) and I woke up this morning to see the leaves all very saggy and grey/brown/yellow. Not entirely sure if its a fungus though. I've included a pic. Leaves are very saggy so I'm wondering if I've over-watered it and clogged up the roots.

    Are they in a greenhouse and close to the glass?
    Just wondering whether those leaves were cooked yesterday.

      Hey VC, yep they're in a greenhouse and were pushed up quite close to glass. You think they might be burnt?

        Looks like cooking for me too. Nothing to worry too much about, it's got plenty more leaves. Some greenhouse shading would help stop it happening again though.

          Just a thought - I noticed my tomato leaves in the sitting room were going papery and brown, and assumed it was because they were in the hot sunshine. But the problem has got worse and the plants are now looking quite sick. Today I noticed lots of little black dots on the window glass which on closer inspection are red spider mites. I'm kicking myself because I've already had this problem once in my friend's greenhouse. Whether I brought them home with me or whether they are just having a bonanza year I don't know - I've not had them here before, but they do particularly like heat. Anyway have a good close look for signs of tiny little spiders and webs on the leaves (a magnifying glass will help). I've ordered some predatory mites which I hope will eat them all for breakfast.

            It is a great year for bugs,I noticed one of my tomato plants looking a bit sad & checked under the leaves,red aphid,not many of them thankfully. Never had them before on tomatoes,loads of black aphids on my runner beans & my nasturtiums have been a good trap crop for the black aphids. A few whitefly around too,I'm bug squashing here everyday....

              I also think that they probably got dry in the heat yesterday and then scorched. Pots in this heat will need watering a couple of times a day.
