Spring Delivery! We begin shipping in mid-March, which is the perfect time for planting for most zones. Dahlias can be planted up to mid-June in most regions and will continue to bloom until the first frost!
Spartacus produces a rich, so red it's almost black, velvety bloom. You can expect this decorative dahlia to produce huge blooms up to 9-12" across.
Contains 2 dahlia tubers
Dig a hole about twice the size of the Dahlia tuber. The eye should face up (this is the part of the root from which the stem grows). Cover with just enough soil so that the top of the tuber is covered.
Space about 2-3' apart.
As the stem emerges cover with soil again. This second covering encourages a strong stem, which will help support the heavy dahlia blooms.
Zones 8-11.
The more sun your dahlias receive, the bigger the flowers will be. Dahlias need about six hours of direct sun a day to thrive.
A well-drained location is absolutely critical for healthy dahlias. Make sure your dahlia roots never sit in soggy soil.
If possible, select a location that offers some protection from wind and heavy rains.
Dahlias like the soil to warm up before being planted. They can be planted any time after ground temps regularly hit 70F and all the way through mid-June in most parts of the country.

Additional Care Instructions
Water young dahlias sparingly, as too much water can lead to rot. Water mature dahlias regularly.
Dahlias will continue to bloom until the first frost. A hard frost will kill the plant, so it is advisable to harvest tubers before that happens. Store harvested tubers in a cool, dry location overwinter and plant in the spring.
