Can bulbs survive in outdoor containers below freezing?

Question

Planting spring bulbs in outdoor containers where we have freezing temperatures during the winter

Answer 1

You are in zone 7a. The rule of thumb is when gardening in containers, the lowest hardiness zone of the plant should be at least two below yours. So check the hardiness zone for the bulbs you are planting. For example, daffodills typically can survive to zone 3 so that is more than two zones below yours. Or you can leave the pots in the garage or on the porch. But do give them water. Wait till late October or early November to plant bulbs in zone 7.
