When can I plant Stocks in Zone 4a

One of the best tools that we have as gardeners to help us determine 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.

You can estimate when to plant stocks in Zone 4a by checking out the USDA zone info.


Planting Calendar for Stocks

Frost tolerance for stocks: Tolerant of a very small amount of frost.
When you should plant them: Up to 3 weeks before last frost.

Since stocks are one of those plants that can tolerate a tiny bit of cold weather you can plant them just a tiny bit earlier in the year than more sensitive plants.

The earliest that you can plant stocks in Zone 4a is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant stocks and expect a good harvest is probably August. Any later than that and your stocks may not have a chance to grow to maturity. If you are starting your stocks indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 4a. In the coldest months of winter we can expect an average low temperature of -30°F.

Since the USDA zone info for Zone 4a is just an average our actual date of last frost will vary from year to year. Half of the time in Zone 4a we get surprised by a frost after May 15 so make sure that you are ready to protect your stocks in the event of a surprise late frost.
