EARTH UP POTATOES
IF YOU planted your first early potatoes a few weeks ago, they will need earthing up.
Gather some soil from between the rows, piling it in a ridge along the line of potatoes. The stems will be partially buried. Take care not to disturb developing tubers. If rows are close together, be extra cautious.
Earthing up protects vulnerable stems from untimely frosts and helps to improve yields.
