A general-purpose potting soil is suitable for spider plants. Feed plants during periods of active growth with a water-soluble or a time release houseplant fertilizer. Follow the label recommendations. Temperatures between 65 and 75 F during the day and 50 to 55 F at night are ideal. Move spider plants a few feet from windows to protect them from drafts during the winter.
Spider plants form thick, fleshy tuberous roots.
Divide and repot plants before the roots expand enough to crack the container. They can be repotted at any season. Wait four to six months before feeding newly potted plants. Spider plants produce most of their offshoots when the days shorten in the fall. You can start new plants at any season from the plantlets.
