Alliums in pots
I have planted 50 small pots with 1 Allium bulb in each. They are plastic pots. Can I leave outside or will frost hurt them. I cannot knee down to plant, so will get someone to transplant later in March/April.

Most Alliums are quite cold-hardy and can grow outdoors down to USDA gardening zone 3. Plants in containers are more exposed to the cold, but even so, these are very cold-resistant bulbs, so they should be fine outdoors.
