Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

By referring to the USDA zone info for Zone 1b it's possible to estimate when it's a good idea to plant galium.

Planting Calendar for Galium

Frost tolerance for galium:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Galium can survive in moderate cold which means that you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant galium in Zone 1b is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant galium and expect a good harvest is probably July. Any later than that and your galium may not have a chance to fully mature. If you are starting your galium indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 1b the average date of last frost happens on June 15. It might get as low as -55°F during the coldest months of winter.

It's important to remember that the actual date of last frost is an average because it is based on the USDA zone info for Zone 1b and it can change quite a bit from year to year. Half of the time in Zone 1b you get a frost after June 15 so always be ready to protect your galium in the event of one of those late frosts.
