Spider Plant: The Forgiving Houseplant That Multiplies for You

Spider plant is the first plant I recommend to anyone who has killed three houseplants in a row. It tolerates low light, irregular water, and inexperienced repotting. Within a year of healthy growth it sends out arching wiry runners (stolons) tipped with small plantlets — the spider babies. You can fill a kitchen window with one mother plant.

The variegated cultivars ('Vittatum' with white center stripe, 'Variegatum' with white edges) are the supermarket standard. The all-green species is faster and less brittle but visually less popular. All are pet-safe — non-toxic to cats and dogs, which makes spider plant one of very few houseplants I recommend without caveat.

Care guide

Bright indirect light is the sweet spot. Direct south-window sun scorches the variegated leaves. Water when the top inch is dry — usually weekly in summer, every 10–14 days in winter. Yellow lower leaves means overwatered; the recovery is to let the soil dry out further between waterings.

Brown leaf tips

The eternal spider-plant problem. Cause: fluoride and chlorine in tap water. Solution: water with rainwater or filtered water, or fill the watering can the night before so chlorine off-gasses. Brown tips already there will not green back — snip them off at an angle.

Propagation (the babies)

Two methods. The easy one: sit a baby with developing roots on a small pot of moist potting mix next to the mother, still attached. Once the baby's roots establish in the new pot (2–4 weeks), snip the runner. The faster one: cut a baby off the mother, sit it in a glass of water until roots are an inch long, then pot up.

No babies?

Spider plants reliably produce runners only when slightly pot-bound and getting short autumn days (12 hours or less of light). If yours has been in a too-big pot for a year, expect lots of leaves, no babies. Repot down a size, accept a stressed look for two months, and watch the runners appear.
