Irish Cobbler Potato
✓ In your garden
Irish Cobbler is a white potato, ready in about 90–120 days. An all-purpose potato — boil it, roast it, or mash it (texture varies by variety, from waxy to mealy). You grow potatoes from seed potatoes (not true seed): plant the pieces after frost, then hill soil up around the stems as they grow so the tubers stay covered.
“An all-purpose potato — good boiled, roasted, or mashed.”

Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around late Jun, well before your typical frost (~late Oct).

Growing Irish Cobbler — the things that trip people up
- Plant certified seed potatoes, not grocery ones or true seed — cut larger ones so each piece has an “eye,” and let the cuts dry a day before planting after your last frost.
- Hill soil (or straw) up around the stems as they grow. Tubers form near the surface, and any that see sunlight turn green and mildly toxic — keep them covered.

Common questions about Irish Cobbler
How long does Irish Cobbler take to grow?
About 90–120 days. Harvest “new potatoes” early and small, or wait until the tops die back for full-size storage tubers.
Do I grow Irish Cobbler from seed?
No — potatoes grow from seed potatoes (small tubers with eyes), not true seed. Plant certified seed potatoes to avoid disease.
Why do I hill potatoes?
Tubers form near the surface. Mounding soil up around the stems gives them room and keeps them dark — exposed potatoes turn green and mildly toxic.
