One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of making a decision about when it's possible to plant saxifraga is to use the USDA zone info for Eden.

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.

Since saxifraga do ok in moderate cold you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant saxifraga in Eden 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 saxifraga and expect a good harvest is probably August. You probably don't want to wait any later than that or else your saxifraga may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your saxifraga indoors.

Last Frost Date

In Eden the average date of last frost happens on April 15. In the coldest months of winter you can expect an average low temperature of 5°F.

Since the USDA zone info for Eden is just an average the actual date of last frost changes from year to year. Half of the time in Eden last frost occurs after April 15 so be sure to be ready to cover your saxifraga if you have a surprise late frost.
