One of the best tools that you have as gardeners to help us estimate your 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 your area.

The first opportunity to plant dracaena in Zone 4a should be determined by referring to the USDA zone info.

Planting Calendar for Dracaena

Frost tolerance for dracaena:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Dracaena tend to make it in pretty solid cold which tells us that you can plant them earlier in the year than other frost tender plants.

The earliest that you can plant dracaena in Zone 4a is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant dracaena and expect a good harvest is probably August. You probably don't want to wait any later than that or else your dracaena may not have a chance to fully mature. Starting your dracaena indoors is a great way to get them started a little bit earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 4a. It might get as low as -30°F during the coldest months of winter.

It's important to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Zone 4a and it changes from year to year. Half of the time in Zone 4a there is a last frost after May 15 so just be sure to be ready to cover your dracaena in the event of a late frost.
