Before planting it is a good idea to find your USDA Zone info to determine 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 estimating when it's a good idea to plant melons is to use the USDA zone info for Wyoming.

Planting Calendar for Melons

Frost tolerance for melons:	Not tolerant of frost.
When to plant:	After the last frost has passed.

Since melons are not cold tolerant it is important to wait until after the last frost has passed before you can plant them.

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

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Wyoming. In the coldest months of winter you can expect an average low temperature of -15°F.

Remember that USDA zone info for Wyoming is not always accurate and the actual date of last frost changes from year to year. Half of the time in Wyoming there is a last frost after April 15 so just be sure to be ready to protect your melons if you have a late frost.
