The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Moscow you can estimate when it's possible to plant cuphea by referring to the USDA zone info.

Planting Calendar for Cuphea

Cuphea require warm weather which tells us that it's important to wait until it warms up after the last frost when the weather gets warmer before you can plant them.

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

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Moscow. It might get as low as -10°F during the coldest months of winter.

Remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Moscow and it changes from year to year. Half of the time in Moscow you get a frost after April 15 so always be ready to protect your cuphea in the event of a late frost.
