Saxifraga tend to make it in very little cold which tells us that you can plant them slightly earlier in the year than other plants that might not handle the cold.

The earliest that you can plant saxifraga in Peru 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. If you wait any later than that and your saxifraga may not have a chance to fully mature. 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 April 15 in Peru. In the coldest months of winter you can expect an average low temperature of -15°F.

Just be sure to remember that the actual date of last frost is an average because it is based on the USDA zone info for Peru and it can change quite a bit from year to year. Half of the time in Peru last frost occurs after April 15 so make sure that you are prepared to cover your saxifraga if you have a surprise late frost.
