If you made an earlier sowing of Salad Leaves, Spring Onions or Radishes there may be some large enough to pull already, don’t leave them until they are full size – the secret is to start harvesting as soon as you can - that way they won’t run to seed before you have time to eat them.
Covering them with Mesh Insect Netting or a Net Cloche will keep out carrot and cabbage root-fly whist also giving some protection from cold nights.
Continue harvesting the last of your Sprouting Broccoli, Leeks and Kale, sprinkle some Organic Extra on the soil around the plants to give them a final boost before they finish cropping.
You can sow Peas in succession from now until June to give you a really long cropping period. Sowing a short row every 2 or 3 weeks will give good continuity of cropping.
Applying a top dressing of Organic Extra a day or two before any planting will release nutrients to your plants over a long period and help add humus to your soil.
