Tomato leaf problem

2»

Posts

  • I'm in Staffordshire! The tomatoes are all in large pots. The lower leaves are all absolutely fine, it's only the upper leaves, but it's not like the usual leaf curl due to heat, they are properly distorted and wizend.....it's like the edges of the leaf are like when you've left a lettuce out in the kitchen for a few days - all limp and floppy!
  • Also...forgot to say, where you would normally pinch out the side shoots, I've left them on at the top, just to see how they grow, and they look like normal healthy shoots...

    They'll be struggling to take up enough water to reach the farthest ends of the stems in pots. It's not uncommon, especially at the size they are, and coupled with not enough ventilation/protection in the heat. Tomatoes don't do so well once temps get above high twenties.
    Our temps here have been like that recently - mid to high twenties, and inside a greenhouse of any kind, that's magnified by a huge amount, so the ventilation and shading needs to be there early in the day   :)

    If it was the compost, the lower leaves wouldn't be happy, and the plants wouldn't have got to that size by now if the compost was infected in any way.

    My tomatoes are also showing signs of heat stress with temps in the upper 30's in the greenhouse over the last couple of weeks. The tops of the plants are twirling around and the leaves growing weirdly, but they'll sort themselves out now it's a bit cooler.
    I don't have the problem with wilting leaves so likely as @Fairygirl has said above.

    As you’ve explained so clearly by likening them to those lettuce leaves on your worktop, the tomatoes are suffering because of the heat … as @Fairygirl explained they can’t pump enough water up to the top to keep up with the amount lost by transpiration in the heat.

    My toms are fine, but they aren't anywhere near the size of the OP's. The bigger they are, the harder it will be for them.

  • I think I'll hold on to them for a while and see how they get on.....thanks everyone for your wisdom and kindness

    Just a thought too @Heather120 - if you're always going to be growing inside and in pots, it might be worth using a good, hefty, soil based compost or even just soil from your garden if you have any available.
    Obviously- that's no use this year, but it might be better in future, as that would help retain moisture better in long hot spells  :)
