When can I plant Lemon grass in Zone 1a

One of the best tools that we have as gardeners to help us figure out our 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 our area.

It's a good idea to figure out when it's a good idea to plant lemon grass by reviewing the USDA zone info for Zone 1a.

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

The last month that you can plant lemon grass and expect a good harvest is probably July. You probably don't want to wait any later than that or else your lemon grass may not have a chance to fully mature. You can get started a few weeks earlier by starting your lemon grass indoors.

Last Frost Date

On average the last frost when the weather gets warmer is on June 15 in Zone 1a. We can expect an average low temperature of -60°F in the coldest months of winter.

Since the USDA zone info for Zone 1a is not always accurate our actual date of last frost is different every year. Since half of the time in Zone 1a there is a last frost after June 15 be ready to protect your lemon grass if we have one of those late frosts.
