The first plant I ever propagated was a spider plant. My grandmother had one that covered an entire windowsill — with its long arching runners and dangling plantlets, it looked like the plant was slowly taking over the room. She gave me a baby cutting in a plastic cup of water, told me to pot it when the roots were 3cm long, and within a month I had my own plant. Spider plant care is that approachable. And the rewards — those cascading babies, the striped foliage, the air purification — are genuinely worth it.
What Is a Spider Plant?
The spider plant (Chlorophytum comosum) is a perennial herb from Southern Africa. The name comes from the small plantlets that dangle from the parent plant on long runners, resembling spiders on a web.
- Scientific name: Chlorophytum comosum
- Common names: Spider plant, airplane plant, ribbon plant, hen and chickens
- Origin: Southern Africa
- Indoor size: 30–60cm wide; runners can reach 90cm
- Growth rate: Fast in good conditions
- Toxicity: Non-toxic to cats and dogs (ASPCA approved)
- NASA Air Study: Ranked among top air-purifying plants
Spider Plant Care Guide
Spider plants forgive a lot, but they thrive when you get these basics right.
| Care Aspect | Requirement | My Tip |
|---|---|---|
| Light | Bright to medium indirect light | Tolerates low light but grows slower and produces fewer babies |
| Watering | Every 7–10 days; top inch dry | Use filtered water — fluoride causes brown tips |
| Soil | Well-draining potting mix | Standard mix with perlite is ideal |
| Pot | Any with drainage; slightly snug is fine | Root-bound plants produce more runners and babies |
| Fertiliser | Monthly (spring–summer) | Don't over-fertilise — causes brown tips |
| Temperature | 13–27°C (55–80°F) | Frost will kill it; cold draughts cause leaf yellowing |
| Humidity | Average home humidity fine | Misting helps prevent brown tips in very dry air |
| Repotting | Every 1–2 years or when roots escape | Wait until slightly root-bound before repotting |
How to Propagate Spider Plant Babies
This is the best part of owning a spider plant. A mature, happy plant produces long runners with multiple small plantlets (called spiderettes or pups). Here are the two methods I use:
- Water propagation: Cut a plantlet from the runner when it has small nubs (proto-roots). Place in a glass of water, keeping the leaves above water. Roots appear in 1–3 weeks. Once 3–4cm long, pot into moist soil.
- Direct soil propagation (my preferred method): While the runner is still attached to the parent, place the plantlet on top of a small pot of moist soil and secure with a wire pin or hair clip. Once rooted (3–4 weeks), cut the runner. Faster establishment than water rooting.
I've given away over 40 spider plant babies from two parent plants over the years. They make genuinely great gifts — in a small pot with a note that says "this one's hard to kill."
Common Spider Plant Problems & Fixes
- Brown tips: The most common complaint. Almost always fluoride or chlorine in tap water. Switch to filtered or rainwater immediately. Low humidity and over-fertilising can also cause brown tips.
- Yellow leaves: Overwatering or root rot. Let soil dry more between waterings. Check roots for brown mushiness.
- Pale, washed-out colour: Insufficient light. Move closer to a window.
- No babies/runners: Usually in low light or too large a pot. Move to brighter spot and wait. Root-bound plants produce more runners.
- Limp, drooping leaves: Underwatering. Water thoroughly — recovery is quick.
- Pests: Spider mites (in dry conditions), aphids, mealybugs. Wipe leaves with neem oil solution or insecticidal soap.
Frequently Asked Questions
Every 7–10 days in summer and every 14 days in winter. Allow the top inch of soil to dry between waterings. Spider plants are moderately drought-tolerant — underwatering is far less damaging than overwatering. Always use filtered water or rainwater to prevent brown tips from fluoride.
Spider plants are listed as non-toxic to cats and dogs by the ASPCA. However, cats are often attracted to them and may chew the leaves — which can cause mild stomach upset. The plants contain mildly hallucinogenic compounds similar to opium that cats find appealing. Keep them in a hanging basket out of reach to be safe.
Brown tips are most commonly caused by fluoride or chlorine in tap water. Switch to filtered water or leave tap water to sit overnight before using it. Low humidity, over-fertilising, and underwatering can also cause brown tips. Trim off brown tips with clean scissors — it doesn't harm the plant and it looks much better.
Spider plantlets (spiderettes) grow on long runners from the parent plant. You can root them while still attached by placing the plantlet in a small pot of moist soil until it roots, then cut the runner. Or cut the plantlet and place in water — roots appear in 2–3 weeks. I prefer the direct soil method — faster establishment, more robust plants.
Spider plants produce runners when they're slightly stressed — typically slightly root-bound and receiving good light. If your plant is in a large pot in low light, it'll focus on growing rather than reproducing. Move it to a brighter spot and only repot when the roots are clearly escaping the drainage holes.
Final Thoughts on Spider Plant Care
The spider plant is a classic for a reason. It's genuinely hard to kill, produces an endless supply of babies to share, purifies the air, and looks great in a hanging basket. The main thing to remember: filtered water and good light. That's really all it takes. If you're just starting out with houseplants, I'd recommend a trio of spider plant, pothos, and snake plant — three completely different looks, almost identical care difficulty.
