Also called airplane plant, ribbon plant, spider ivy.
About Spider plant
Chlorophytum comosum · also called airplane plant, ribbon plant · houseplant
Spider plant is a beginner-favourite trailer with arching grassy leaves and dangling pups that root readily. It tolerates a wide range of household conditions but is famously fussy about fluoride in tap water. Pet-safe by ASPCA standards.
Chlorophytum comosum is an evergreen perennial of the asparagus family native to tropical and southern Africa, ranging from West Africa and Ethiopia to South Africa, and naturalised widely elsewhere.
It grows well in a free-draining loam-based mix and tolerates dry soil between waterings thanks to its tuberous root reserves.
Preferred mix: Standard potting compost
Watch for — No pups: Spider plants pup when pot-bound and getting enough light — be patient.

Why spider plant needs this mix
Spider plant is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Spider plant is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons spider plant struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates spider plant's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for spider plant.
pH — does it matter for spider plant?
Spider plant is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A decent bagged houseplant compost works for spider plant as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all spider plant needs — the free-draining mix does the rest.
Refresh spider plant's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for spider plant covers the timing and technique step by step.
