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

A way of making a decision about when it's the best time to plant browallia is to consult the USDA zone info for Moscow.

Planting Calendar for Browallia

Frost tolerance for browallia:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

Since browallia do not do well in cold weather it's necessary to wait until after the last frost has passed before you can plant them.

The earliest that you can plant browallia 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 browallia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your browallia may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your browallia indoors.

Last Frost Date

On average the last frost is on April 15 in Moscow. You should expect an average low temperature of -10°F in the coldest months of winter.

Always keep in mind that the actual date of last frost is an average because it is based on the USDA zone info for Moscow and it changes from year to year. Half of the time in Moscow there is a last frost after April 15 so make sure that you are prepared to protect your browallia if you have one of those late frosts.
