The Russian Banana Fingerling potatoes have grown six inches or so above the soil and it is time to hill them up. In this case it means adding a layer of compost and a layer of straw to the planting basket. Easily done when the materials are on hand.
Meanwhile the Yukon Gold potatoes are coming along. The sprouts which were just peeking out of the soil last week have formed sturdy little clusters of dark green leaves.
