Hi Paul,

This does not look like a disease. When I first saw the photo I immediately thought "wind or cold damage".

We've been seeing that sort of leaf damage on tomato plants that are sold by nurseries and left outside on very chilly nights and/or windy days (nurseries tend to receive their plants a few weeks before we can safely plant them outside).

The problem won't progress, so they will be okay. You've done a good job.

Enjoy your tomatoes!

Hi lionheart,

Thanks for the advice. It's almost hard to believe that they could be damaged by the sun as we usually complain constantly about how cold it is in this country!! However, there were a couple of hot days whilst I was away one weekend, and even though I leave the greenhouse door open now, the temperatures still get quite high in there.

I removed the damaged leaves as there were plenty of healthy ones remaining and I have now planted them in large pots which I'll leave outside, so I look forward to a nice crop this year.

Thanks again,

Paul

Excellent! Yes, too much heat will do that too. Enjoy those tomatoes. :-)
