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.
