To plant a hanging basket, first determine the plants you want to use and how you’d like to see them positioned. For this project, Martha used flax lily in the center, and flanked it with coleus (Solenostemon ‘Black Magic’) and sweet potato vine (Ipomoea batatas ‘Margarita’). For the sides of the basket, she decided to alternate the coleus with golden pothos (Epipremnum aureum), and Dracaena ‘Compacta.’
Soak some sphagnum moss, and use it to line the basket to about 2 inches from the rim. If the basket has a round bottom, you can give yourself some stability while you work by setting it on a terra-cotta pot. Fill half the basket with potting soil, and arrange the plants you’ve selected for the sides at mid-level by poking the roots or shoots (whichever is easier by size) through the basket and a layer of sphagnum moss. Continue to fill the basket with potting soil; leave an inch or so at the top to facilitate watering. Arrange the rest of the plants, and fill the space around the roots with additional soil. Trim any stray, shaggy moss with scissors, and water the plants as soon as possible.
