When can I plant Chinese chives 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.

A common way of estimating when you can plant chinese chives is to refer to the USDA zone info for Zone 1a.

The earliest that you can plant chinese chives 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 chinese chives and expect a good harvest is probably July. If you wait any later than that and your chinese chives may not have a chance to grow to maturity. Starting your chinese chives indoors is a great way to get them started a few weeks earlier.

Last Frost Date

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

Since the USDA zone info for Zone 1a is just an average our actual date of last frost will vary from year to year. Half of the time in Zone 1a we get a frost after June 15 so make sure that you are prepared to protect your chinese chives if we have one of those late frosts.
