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.

One way of figuring out when it's possible to plant eggplants is to check out the USDA zone info for Denver.

Eggplants are not cold tolerant which tells us that you really should wait until it warms up after all chance of frost has passed before you can plant them.

The earliest that you can plant eggplants in Denver 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 eggplants and expect a good harvest is probably August. You probably don't want to wait any later than that or else your eggplants may not have a chance to grow to maturity. If you are starting your eggplants indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

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

It's important to remember that the actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Denver and it can change quite a bit from year to year. Half of the time in Denver you get a frost after April 15 so be sure to be ready to protect your eggplants if you have one of those late frosts.
