I live in a colder region (Zone 6-3). Can I plant pre-cooled tulip bulbs?Updated 8 months ago
Pre-cooled tulip bulbs are chilled so they are perfect for growing in warmer climates (USDA zones 7b-11) but can thrive and be planted in any zone as long as your ground isn't frozen. The pre-cooling just gives them a head start on their flower development.
