One of the best tools that you have as gardeners to help us figure out your 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 your area.

A common way of making a decision about when to plant asparagus is to refer to the USDA zone info for Newark.

When to plant:	Up to 7 weeks before last frost.

Since asparagus are very cold tolerant you can plant them earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant asparagus and expect a good harvest is probably October. Any later than that and your asparagus may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your asparagus indoors.
