Title: Is this the dreaded Blight?
Post by: Ma Lowe on July 11, 2014, 16:38

Not long got back from  lovely 5 days away only to find this on some of the leaves of my tomatoes. Not all plants have it but I am worried it's the dreaded Blight. If it is what do I do  :(

Are they from lower down?

Looks more like old age to me.

I took the older leaves off before we went away but these leaves are low down and a few further up too.

This is the whole plant which I have moved outside as you can see the leaves are yellowing further up and have the brown bits on them.

Doesn't look like blight to me, either.

Phew!!! I don't know why but I seem to be paranoid about blight this year. I will acclimatise it to the outside and leave it there in the next week.   :D
