Should you cut the tops off potato plants?

Pruning potato vines can help the potatoes mature earlier, before they attain their full size. Pruning potato vines and then leaving them in the soil for at least two weeks, post pruning, will help them develop a thick, protective skin.

Do potato plants need full sun?

Plant potatoes in a sunny place with at least 6 hours of directly sunlight each day. The tubers need to grow in fertile, loose, well-drained soil; hard or compacted soil leads to misshapen tubers. Ideally, soil is slightly acid (pH 5.8 to 6.5) and the soil temperature is at least 45º to 55ºF (7° to 13°C).
