Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of estimating when you can plant celeriac is to refer to the USDA zone info for Sycamore.

Planting Calendar for Celeriac

Frost tolerance for celeriac:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

You can plant celeriac just a bit earlier in the year because they are one of those plants that can tolerate a little bit of cold weather.

The earliest that you can plant celeriac in Sycamore is February. However, you really should wait until March if you don't want to take any chances.

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

Last Frost Date

Since the USDA zone info for Sycamore is not always accurate the actual date of last frost is different every year. Half of the time in Sycamore you get a frost after April 15 so always be ready to cover your celeriac in the event of one of those late frosts.
