What to Sow and Grow in March
Posted by Alix Francis on 16th Mar 2018
March is an exciting month, the days are getting longer, lighter and warmer (depending on what the weather brings).
There are a lot of vegetables, fruits and flowers which can be sown in this month, some will be directly into the ground and some will be in the greenhouse.
It’s best not to try and sow If the weather has covered the ground in snow or frost, wait until it has cleared so the ground is fresh and more suitable for your crops.
Make sure the ground is well prepared and in good condition before you being sowing.
What vegetables to sow outside

Lettuces can be sown if the weather permits, however it might be worth waiting until the end of March to get these sown outdoors. Sowing lettuce outdoors is the easiest method for the best crop. If the climate is still cold, sow them under a cloche.
Onions & Shallots
