Cordyline (ti plant) care

Light

Cordyline thrives in bright indirect light — the conditions just back from a sunny window, with plenty of ambient brightness but rarely any direct rays on the leaves themselves. Bright indirect light keeps colours saturated. Tolerates morning direct sun. If you are not sure whether your spot is bright enough, a free phone lux-meter app at midday is the quickest way to check; aim for 800-1,500 lux.

Watering

Water cordyline when the top 2-3 cm of soil is dry, every 7-10 days. The actual day count varies with pot size, light level, and the season — the finger test (or, better, lifting the pot to feel its weight) is more reliable than a calendar. Empty any drainage saucer after watering so the pot is never sitting in water. Likes consistent moisture; sensitive to fluoride in tap water.

Soil and pot

Cordyline grows best in rich free-draining houseplant mix. Compost with 20% perlite; a pot with drainage holes is essential. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Cordyline sits happiest at around 50-60% humidity and 18-27°C (65-80°F). Higher humidity prevents brown leaf edges. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed cordyline sparingly. Balanced liquid feed at half strength every 4 weeks in growing season. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on cordyline in the Growli community. Each is annotated with the most common cause so you know where to start.

• Brown leaf tips — Fluoride toxicity; switch to filtered or rainwater.
• Fading colour — Insufficient light; move to brighter indirect light.
• Yellow lower leaves — Old leaves shed normally as the cane forms.
• Spider mites — Stippling and webbing in dry rooms; rinse foliage and raise humidity.

Propagation

Cane cuttings 10-15 cm long root in moist mix or water under warmth. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Cordyline is toxic to pets. ASPCA lists Cordyline fruticosa as toxic to cats and dogs due to saponins. Symptoms include vomiting (sometimes bloody), depression, and loss of appetite. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
