Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

As shoots appear, draw soil over them if there is still a possibility of frost. Once the shoots are hand height, earth them up by drawing more soil around them leaving the top of the shoots still showing to keep the actual potatoes covered. If any potatoes get exposed to light and turn green they should not be eaten. Make sure potatoes are kept watered in dry weather.

Harvesting

Once the foliage has wilted harvest the main crop within a couple of weeks, digging in from the side to avoid damaging the tubers.
