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. Detach them once roots have formed and pot directly into moist growing mix. Vittatum' is the most common variegated cultivar. Variegatum' has white-edged leaves 10 to 16 inches long and up to an inch wide.
