Help My Tomatoes!

[tomcono]

Hi all,
I recently purchased some tomato plants from my local supermarket and they've been doing fine and some tomatoes have recently started growing. However in the past week I came home to find the leaves had all curled so I gave them lots of water which seemed to sort the problem out, then the past few days I noticed yellow spots on the leaves which I found out was due to over watering, so I just thought I hadn't found the right balance yet. However, I got home tonight to find the leaves had curled again even though the plants still had plenty of water, anyone know why? I'm growing them on a window sill in pots.

Tom, Leaf curl in toms is not necessarily a bad thing, providing the leaves are a nice green colour.

How big are your pots, how big are the plants, are the plants in direct sunlight and can you post a pic.

There are a lot of things that could cause your tomato leaves to curl. If you could let us know the answers to Colin's questions that wuold go a long way to helping us advise you, as would a piccie. Tomato leaves curl up with heat stress - because I can only get to my polytunnel every second day, and because with the weather in June being so changeable, I haven't been able to ventilate accordingly, all my toms have curly leaves -however they are still green and healthy and flowering and fruiting their little socks off, so please don't worry too much at the moment.

The pots are quite small for the plants so I think I'll have to re-pot them tomorrow, they get quite a lot of sun in the day, normally direct sunlight from about noon till five o clock weather permitting. The leaves are green apart from the yellow patches, unfortunately I am unable to post a picture though

Tom,

If the plants are root bound in their pots they are not getting enough nutrients. Gently remove a plant from its pot and look at the roots, if you can see masses of root they certainly need potting on. Don't put them into to bigger a pot, just up one size if you can.

If you can stand them in a dish and water from the bottom so much the better but do not let them stand in water as this will rot the roots.

Also if you can shade them slightly during the day maybe with a mesh curtain this will help as well.

Hope this helps Colin

Ok I'll try that tomorrow, do you mean just put them in a dish for a little while? I'll let you know how I get on, thanks a lot for your help

^ water them like this: YouTube - ‪how to water seedlings‬‏

They need bigger pots now ~ drying out isn't good for them, you're likely to get blossom end rot on any fruits
Tomatoes are extremely thirsty plants

I've just potted them on to bigger pots now, the pots they were in were definitely too small as I could see lots of roots when I pulled the plant out of the pot. I have also put some transparent plastic on the window to hopefully diffuse the light and stop the leaves getting burned. If this doesn't work I'll let you know

Try putting old net curtains on the windows. Failing that, if you have a DIY store near you you could buy the white window shading that can be painted on to the glass and can be washed off at the end of the season.

I have also put some transparent plastic on the window

So ... you've just double-glazed the hot window

Could it be magnesium deficiency ?
