Ipomoeas are great additions to combination planters, but they can sometimes overwhelm less vigorous plants. If you are like me you can let your combination plants duke it out Darwinian style, however, if you prefer to keep a more balanced look to your combination planters, you can cut back or remove stems at any time.
Ipomoeas also make great annual groundcovers in the landscape.
In fall before first frost, dig, dry and store tubers in a dry medium (vermiculite or peat) in a cool dry corner of the basement. When tubers sprout in spring, cut them into sections (at least one eye per section) and plant the sections outdoors after last frost date. Tubers can also be sunk ½ way into a large-mouthed glass jar of water in early spring to generate sprouts that can be removed and planted. Container plants and or rooted cuttings taken in late summer may be overwintered indoors in bright sunny locations.
Potatoes formed by ornamental sweet potato vines are edible but are not as flavorful as those selected as a food crop.
An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.
