One of the first steps you take when you are estimating your gardening schedule is find your 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 Maywood you can determine when it's a good idea to plant polygonums by reviewing the USDA zone info.

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

The earliest that you can plant polygonums in Maywood 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 polygonums and expect a good harvest is probably August. Any later than that and your polygonums may not have a chance to really do well. You can get started a few weeks earlier by starting your polygonums indoors.
