Quick Overview

Blanco Duro is a medium sized onion with pungent firm flesh. Good storage onion and tolerant to pink root disease.

How to Plant Bulb Onions

Onion bulbs are quite hardy and can withstand 20° F frost. They should be set out 4-6 weeks prior to the last expected frost. When your plants arrive they should appear to be quite dry. DO NOT WET THEM NOR STICK THEIR ROOTS IN WATER. Unpack them and store them in a cool, dry place until it is time to plant. They should last about 3 weeks kept this way. Do not worry that your plants seem dry. They will "shoot" new roots and new, green tops as soon as they are planted. Be sure to specify on your order when you want your plants to arrive.
