One of the first steps you take when you are figuring out 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 Mountain Home you can figure out when it's possible to plant bidens by using the USDA zone info.

Planting Calendar for Bidens

Frost tolerance for bidens:	Not tolerant of frost.
When to plant:	After the last frost.

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

The earliest that you can plant bidens in Mountain Home 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. 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.

Last Frost Date

On average the last frost has passed is on April 15 in Mountain Home. You can expect an average low temperature of 0°F in the coldest months of winter.

Half of the time in Mountain Home there is a last frost after April 15 so just be sure to be ready to protect your bidens in the event of a surprise late frost.
