Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The best time to plant bidens in Eden should be estimated by reviewing the USDA zone info.

Bidens require warm weather which means that it's important to wait until it warms up after the last frost has passed before you can plant them.

The last month that you can plant bidens and expect a good harvest is probably August. Any later than that and your bidens may not have a chance to fully mature. You can get started a few weeks earlier by starting your bidens indoors.
