The Q&A Archives: Multiple potato plants

Question: Some seed potatoes I planted now have multiple stems growing from each potato (probably due to multiple eyes). Do I need to prune the plant to a single stem? Or can I let the multiple stems (spaced closely together) continue to grow?

Answer: Potato plants generally grow multiple stems, and that's a good thing. The leaves are manufacturing energy (through photosynthesis) and transporting it down through the stems to the roots where tubers will develop. Leave the stems and watch for flowers, which indicate the tubers are swelling. You can harvest baby potatoes after the flowers fade, or leave the spuds to grow until frost kills the tops of the plants.
