One of the first steps you take when you are making a decision about 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 Lincolnshire you can estimate when it's a good idea to plant alternanthera by using the USDA zone info.

It's not a good idea to plant alternanthera until after the last frost because they require warm weather.

The earliest that you can plant alternanthera in Lincolnshire 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 alternanthera and expect a good harvest is probably August. Any later than that and your alternanthera may not have a chance to fully mature. If you are starting your alternanthera indoors then you might be able to get away with starting them a little bit earlier.
