One of the best tools that you have as gardeners to help us estimate 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.

In Riverside you can estimate when to plant neeps by using the USDA zone info.

Since neeps require warm weather you need to wait until after the last frost has passed before you can plant them.

The earliest that you can plant neeps in Riverside 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. Any later than that and your neeps may not have a chance to really do well. If you are starting your neeps indoors then you might be able to get away with starting them a couple of weeks earlier.
