The tomatoes have shot up since the weekend. The stems stems have nearly doubled in length. They must feel that Spring is in full flow here in London and the weather has been amazing. You can see how the lower part of the stem looks a little bit older and more hairy. The new part which has grown in the last couple of days is still light green.
When they sleep the leaves close up. I think they look like they are stretching up because they have grown so tall. Every night they just stretch and stretch until they are taller in the morning!
