Last Frost Date

In Zone 5a the average date of last frost happens on April 15. We should expect an average low temperature of -20°F in the coldest months of winter.

Always keep in mind that our actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 5a and it can change quite a bit from year to year. Since half of the time in Zone 5a it frosts late in the year after April 15 be ready to protect your crassula if we have one of those late frosts.
