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.

In Flagstaff you can figure out when it's possible to plant lovage by looking at the USDA zone info.

Planting Calendar for Lovage

Frost tolerance for lovage:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Lovage tend to make it in a tiny bit of cold which means that you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant lovage in Flagstaff is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant lovage and expect a good harvest is probably August. Any later than that and your lovage may not have a chance to grow to maturity. If you are starting your lovage indoors then you might be able to get away with starting them a couple of weeks earlier.
