I start sowing inside in modules in the last week of February. Lettuce, spinach, herbs like coriander and dill, early brassicas, peas. They are all in the unheated greenhouse slowly growing. Should be able to put them in the ground first week of April, under fleece. Toms and chillis are inside under lights for a few hours a day to top up the daylight. Broad beans were planted out a couple of weeks ago, they are growing OK now
