Planting in the Landscape

If you have purchased your plant, make sure the hole is twice the width of the container while keeping the depth the same as the container. Prior to placing the plant in the hole, make sure to test the hole first. After the hole has passed the test, cut away the pot, tease the roots with your fingers, and place in the hole. Fill in with the removed soil.
If you are planting more than one plant, space them out three to six feet apart.
Planting in a Container
While the ornamental sweet potato vine looks wonderful by itself in a hanging basket or container garden, consider combining it with other plants.
When using it in a container garden, one will first need to select the container. To avoid root rot, choose a container with a drainage hole. Once you have selected your pot, wash and sterilize it. Allow it to dry in the sun. After it has completely dried, place drainage material over the drainage hole and fill the container so that only ¼ remains to be filled with an all-purpose potting soil.
Next, fill your container with your chosen plant material but do not forget to tease the roots of each plant. Once all plants have been added to the container, fill in with soil until you reach one inch from the top. Leaving this margin will create space for watering and will reduce the chances of runoff.
Water in the container and add additional soil as needed.
Fertilized every two weeks with a balanced, all-purpose fertilizer that is diluted to ¼ the regular strength.
