Now is the time to plant Tom Thumb Lettuce seed on the kitchen window sill for an early homegrown lettuce from the vegetable garden.
As soon as it comes up transfer the lettuce to a frost-free unheated greenhouse, or a very light patch under glass. When the seedlings are large enough to handle, thin out gradually, but keep them about 15cm (6in) apart.
Tom Thumb is the smallest lettuce.
compact, solid butterhead type
very fast growing
This lettuce will be ready to harvest about 65 days after sowing.
To test if it is ready to harvest, press the head gently with the back of the hand, it is ready if it feels solid and barely yields to pressure.
We are in the UK where we are having relatively mild winters. Growing the lettuce in a cold greenhouse or under plasic cloches in the garden keeps the frost off! Nothing like the first fresh lettuce of the season!
