When can I plant Lavender in Zone 1a

You can determine when you can plant lavender in Zone 1a by looking at the USDA zone info.

The earliest that you can plant lavender in Zone 1a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant lavender and expect a good harvest is probably July. Any later than that and your lavender may not have a chance to grow to maturity. Starting your lavender indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 1a the average date of last frost happens on June 15. We should expect an average low temperature of -60°F in the coldest months of winter.

Remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 1a and it is different every year. Half of the time in Zone 1a it frosts late in the year after June 15 so always be ready to cover your lavender in the event of a late frost.
