Hi, this is my first post and I'm newly re acquainted with gardening so be gentle with me !
I've been growing Gherkins, variety cucumis sativus, from seed. At first I was getting a very low germination rate, probably about 30%. They started off in fibre pots indoors perfectly fine and I started hardening off when they where at the 3 leaf stage and about 6 or 7cm high. However when planted out in the permanent bed, the leaves quickly yellow from the outer edges in and the plant withers and dies. I've tried this 3 times now over the last 6 weeks and get the same result every time. I have no previous experience of this problem and don't know where to start looking for an answer. Can anyone help?
