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

A common way of making a decision about when it's a good idea to plant bidens is to consult the USDA zone info for Hope.

It's a bad idea to plant bidens until after the last frost has passed because they are not cold tolerant.

The earliest that you can plant bidens in Hope 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 bidens and expect a good harvest is probably August. If you wait any later than that and your bidens may not have a chance to really do well. Starting your bidens indoors is a great way to get them started a few weeks earlier.
