Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of determining when it's a good idea to plant celery is to use the USDA zone info for Zone 7a.

Planting Calendar for Celery

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

Celery do well in mild cold which tells us that you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant celery in Zone 7a 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. If you wait any later than that and your celery may not have a chance to fully mature. Starting your celery indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Zone 7a the average date of last frost happens on April 15. It might get as low as 0°F during the coldest months of winter.

Remember that USDA zone info for Zone 7a is not always accurate and the actual date of last frost changes from year to year. Since half of the time in Zone 7a last frost occurs after April 15 be ready to protect your celery if you have a late frost.
