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 Greensboro you can estimate when it's possible to plant portulaca by checking out the USDA zone info.

It's probably a bad idea to plant portulaca until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant portulaca in Greensboro 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 portulaca and expect a good harvest is probably August. Any later than that and your portulaca may not have a chance to really do well. If you are starting your portulaca indoors then you might be able to get away with starting them a few weeks earlier.
