Sweet Caroline Sweetheart Jet Black Sweet Potato Vine Care
Ipomoea Sweet Caroline is easy going and relatively maintenance-free. This plant can take a wide range of sunlight from part sun up to full sun. The more sun this plant receives, the darker the foliage becomes. It has average water and soil fertility requirements. Ipomoea Sweet Caroline has a tendency to shade out slower growing plants, (especially in combination plantings) so trim it back at any time. Apply an annual application of compost or fertilizer to the landscape or a regular fertilizing regimen to containers to promote vigorous growth.
This heat-loving annual is only hardy to zones 11. Prolonged cold fall weather and frost will kill outdoor plants. To overwinter, store sweet potato tubers in a dry dark location until spring.
Sweet Caroline Sweetheart Jet Black Sweet Potato Vine Spacing
If planted in the landscape, allow anywhere from 12 to 18 inches of space between plants. Allow a minimum of 6 inches of space between plants in containers and train vines to cascade over the sides. Use at least a 12 inch or larger container to create your favorite combinations.
