One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

It's a good idea to figure out when to plant lysimachia by referring to the USDA zone info for Fox Lake.

Planting Calendar for Lysimachia

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

Since lysimachia do well in moderate cold you can plant them a little bit earlier in the year than other frost tender plants.

The earliest that you can plant lysimachia in Fox Lake is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant lysimachia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your lysimachia may not have a chance to really do well. If you are starting your lysimachia indoors then you might be able to get away with starting them a few weeks earlier.

Since the USDA zone info for Fox Lake is not always accurate the actual date of last frost is different every year. Half of the time in Fox Lake last frost occurs after April 15 so make sure that you are prepared to protect your lysimachia in the event of one of those late frosts.
