Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Aberdeen you can estimate when to plant saxifraga by referring to the USDA zone info.

Planting Calendar for Saxifraga

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

Saxifraga can survive in some cold which tells us that you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant saxifraga in Aberdeen 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 saxifraga and expect a good harvest is probably September. You probably don't want to wait any later than that or else your saxifraga may not have a chance to really do well. Starting your saxifraga indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is February 15 in Aberdeen. In the coldest months of winter you can expect an average low temperature of 20°F.

Half of the time in Aberdeen last frost occurs after February 15 so make sure that you are prepared to cover your saxifraga if you have a surprise late frost.
