When can I plant Achimenes in Zone 8b

One of the best tools that we have as gardeners to help us determine our gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

In Zone 8b you can determine when it's a good idea to plant achimenes by referring to the USDA zone info.

The earliest that you can plant achimenes in Zone 8b 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 achimenes and expect a good harvest is probably August. Any later than that and your achimenes may not have a chance to grow to maturity. If you are starting your achimenes indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

On average the last frost has passed is on March 15 in Zone 8b. In the coldest months of winter we should expect an average low temperature of 15°F.

Always keep in mind that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 8b and it will vary from year to year. Half of the time in Zone 8b there is a last frost after March 15 so always be ready to protect your achimenes if we have a late frost.
