Maincrop Seed Potatoes

Seed potatoes are classified according to the length of time they take to mature, but this can be influenced by the weather. Maincrop potatoes are higher yielding than first earlies and second earlies and usually have larger tubers. Maincrop cultivars can either be used fresh from the ground or stored in Hessian Sacks for winter use.

When to plant main crop potatoes?

Main crop potatoes, known for their larger size and longer maturation time compared to early varieties, are typically planted from mid-March onwards. This timeline is a general guideline and may vary depending on local weather conditions. Unlike early varieties that can thrive in containers or bags, main crop potatoes require planting in the ground to ensure adequate space for their growth.

When are main crop potatoes ready to harvest?

Maincrop seed potatoes mature in 125-140 days, and if planted in late April, they can be harvested by mid-August, sometimes continuing through to October.
