Growing Pedilanthus Indoors
Devil’s backbone houseplant likes bright indirect sunlight. Plant in direct sun in fall and winter, but give it a little protection from stinging hot rays in spring and summer. Just turning the slats on your blinds can be enough to keep the tips of the leaves from sizzling.
Water the plants when the top few inches of soil feel dry. Keep it only moderately moist, yet not soggy.
The plant produces the best growth with a once per month fertilizer solution diluted by half. Devil’s backbone houseplant does not need to be fed in the dormant seasons of fall and winter.
Choose a draft free location in the home when growing Pedilanthus indoors. It doesn’t tolerate cold breezes, which can kill off the tips of the growth.
Long Term Care of Devil’s Backbone
Repot your plant every three to five years or as needed in a rich houseplant mix with plenty of sand mixed in to increase drainage. Use unglazed pots, which allow excess moisture to freely evaporate and prevent wet root damage.
Unchecked plants may get up to 5 feet in height. Prune off any problem branches and trim back lightly in late winter to keep the plant in good form.
