Why are my tomato plants leaves dry and curled?

Leaf curling is quite a common complaint on tomatoes and there are many causes including environmental stresses and transplant shock. Some varieties even curl their leaves naturally!

Do you know whether the tomato plants had been hardened off before you were given them? If you have put them straight outside then the sudden exposure to the elements and change in temperature may be the cause. Leaf rolling is also often associated with tomato plants that have been over watered, or experienced periods of heavy rainfall. Tomatoes need to be kept reliably moist without becoming too wet or too dry. Quite often, leaf rolling is a temporary response and the plants will improve once their environment improves.

Plants and gardens have always been a big part of my life. I can remember helping my Dad to prick out seedlings, even before I could see over the top of the potting bench. As an adult, I trained at Writtle College where I received my degree, BSc. (Hons) Horticulture. After working in a specialist plantsman's nursery, and later, as a consulting arboriculturalist, I joined Thompson & Morgan in 2008. Initially looking after the grounds and coordinating the plant trials, I now support the web team offering horticultural advice online.
