I planted my Adirondack Blue Potatoes on May 5th. So it's been between 2-3 weeks (18 days to be exact). They are growing at a good pace right now. The surprising thing about them is that they even a hint of blue/purple in the leaves themselves. They are easy to pick out in the potato section of my garden.
How Long Does It Take Adirondack Blue Potatoes to Emerge
It took just over a week for the first leaves to come up. I planted two other varieties (Red Pontiac and German Butterball), but I found that the Adirondack Blue were the first to come up (but only by a day or two). The Red Pontiac caught up pretty quickly and has more leaves now than my Adirondack Blue plants.
Continue to water and weed regularly. When the stems reach about 8 inches tall, I will begin hilling dirt up around the stems, making sure not to cover up the leaves. The hilling is necessary to give the actual potatoes room to grow and to keep them from being exposed to sunlight, which will turn them green, rendering them inedible.
