One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The earliest that you can plant neeps in Princeton should be determined by reviewing the USDA zone info.

When to plant:	After the last frost.

It's a bad idea to plant neeps until after the last frost has passed because they require warm weather.

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