About Cordyline
Cordyline fruticosa · also called ti plant, good luck plant · tropical
Cordyline fruticosa is a tropical evergreen with sword-shaped leaves in green, pink, red, or burgundy. Grown indoors as a colourful upright accent and outdoors as a hedging plant in frost-free climates. Toxic to pets through saponins.
Cordyline fruticosa, the ti plant, is an evergreen woody shrub native to the Pacific Islands, Southeast Asia, and tropical Australia, grown for spear-shaped leaves in green, red, pink, and purple.
Needs a rich, well-drained potting mix kept evenly moist; good drainage is essential to prevent root rot.
Preferred mix: Rich free-draining houseplant mix

Why cordyline needs this mix
Cordyline is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Cordyline 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 cordyline 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 cordyline'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 cordyline.
pH — does it matter for cordyline?
Cordyline 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 cordyline 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 cordyline needs — the free-draining mix does the rest.
Refresh cordyline'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 cordyline covers the timing and technique step by step.
