When can I plant Celery in Zone 6a

One of the first steps we take when we are making a decision about our gardening schedule is find our USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

By using the USDA zone info for Zone 6a you should be able to figure out when to plant celery.


Planting Calendar for Celery

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

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

The earliest that you can plant celery in Zone 6a is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant celery and expect a good harvest is probably August. You probably don't want to wait any later than that or else your celery may not have a chance to grow to maturity. Starting your celery indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Zone 6a the average date of last frost happens on April 15. We should expect an average low temperature of -10°F in the coldest months of winter.

Since the USDA zone info for Zone 6a is not always accurate our actual date of last frost will vary from year to year. Since half of the time in Zone 6a there is a last frost after April 15 be ready to protect your celery in the event of one of those late frosts.
