Hello,

Can anyone tell me why some of my Tomatoes have tough skins?

I grow my Toms in a small greenhouse in the sunniest part of the garden, in
the largest tubs I can buy. I water, feed, ventilate etc as best I can, but
still a few of my Tomatoes have skins so tough that they could be used to
protect a Challenger tank !!

Varieties - This year Moneymaker & Alicante, though I've had the same
problem before with others.

What am I doing wrong ?? All advice welcome

Thanks

KK
