Lettuce seeds are a great way to get the kids out into the garden with you. Lettuce will frequently be added to a child's favourite sandwich, making it one of the easiest vegetables to introduce to a child's diet. It is also one of the easiest vegetables to grow, providing you keep the wildlife away. Lettuce seeds grow in the open and at ground level, making it a very attractive vegetable to eat for all manner of pests. It is normally best to plant lettuce seeds in a place that you can protect or ringfence to avoid losing your delicious crops to animals.
