The delicious spuds have innumerable uses and preparation methods. Such a versatile food is perfect for zone 8.
Potatoes prefer cooler soils. At temperatures above 75 degrees Fahrenheit (24 C.), tuber production slows and when temps reach 85 F. (30 C.), it basically stops. That is why it is important to plant potatoes early in the season when soil is still cool. Potatoes need at least 100 to 120 days for adequate production.
