How much light does a ti plant need?
Ti plants color up best in bright, filtered light. The tough green-leaf kī that Hawaiians have grown for centuries handles nearly full sun once established, while the flashy red, pink, and variegated varieties scorch in hot afternoon sun and want morning sun or bright shade. Too little light and the vivid colors fade toward plain green with stretched, floppy canes. Indoors, put a ti near your brightest window — they sulk in dim corners.
How often should I water a ti plant?
Keep ti soil consistently moist — water when the top inch dries, which in warm weather means two or three times a week for pots. Ti plants are thirsty but hate sitting in swampy soil, so drainage matters as much as frequency. The classic ti complaint, brown leaf tips, usually isn't underwatering: it's fluoride and salts in tap water, which ti are famously sensitive to. If your tips keep browning, switch to rainwater or let tap water sit out overnight, and flush the pot thoroughly every month or two to rinse out accumulated salts.
How do you grow a ti plant from a cutting or 'log'?
Ti is one of the easiest plants in the world to propagate — the old plantation trick is the ti 'log.' Cut a mature cane into 4–6 inch sections, remember which end was up, and either stand them upright in a glass with an inch of water or lay them sideways half-buried in moist potting mix. In a few weeks each log sprouts shoots from the buds along the cane and roots below. Once shoots have a few leaves, pot them up. One healthy cane can become half a dozen new plants, which is exactly how we multiply our nursery stock.
Why are my ti plant's leaf tips turning brown?
Brown tips on ti plants come from three main causes. First and most common: fluoride and dissolved salts in tap water — ti are among the most fluoride-sensitive plants grown, and the damage shows up as dry brown tips and margins. Use rainwater or catchment water if you can. Second: fertilizer salt buildup — flush pots regularly and feed lightly. Third: low humidity or dry wind crisping the leaves. Trim brown tips with scissors at an angle to keep the leaf shape looking natural; the trimmed spot won't regrow but new leaves will come in clean.
What does the ti plant mean in Hawaiian culture?
Kī is a canoe plant — carried to Hawaiʻi by Polynesian voyagers — and few plants work harder in island life. The leaves (lāʻī) wrap lau lau and other food for the imu, are twisted into lei lāʻī, layered into hula skirts, and used in blessings; planting ti around the home is traditional protection and good luck. Green kī was the everyday workhorse, and it remains the variety we recommend for cooking and lei because the leaves are big, flexible, and abundant. When you buy a ti from us, you're growing a piece of Hawaiʻi's living culture.
Can ti plants grow indoors?
Yes — ti make striking indoor plants if you can give them bright light and clean water. Place them near an east or west window, keep the soil lightly moist, and wipe the leaves occasionally so they can breathe. Watch for spider mites in dry indoor air, especially with AC running; a monthly shower in the sink or hose-down outside keeps them clean. Note that ti is toxic to cats and dogs if chewed, so hang it or shelf it out of reach of nibblers.
Ti Plant (Kī) FAQ
Are ti plants toxic to pets?
Yes — ti plants contain saponins that are toxic to cats and dogs if chewed, causing vomiting and drooling. Keep them out of reach of pets that like to chew leaves.
How fast do ti plants grow?
In Hawaii's climate ti grow quickly — a rooted log can become a 3-foot plant in about a year. Growth is slower indoors or in cooler climates.
Can I plant ti outside on the mainland?
Ti are hardy outdoors only in frost-free zones (roughly USDA 10–12). Anywhere that freezes, grow ti in a pot and bring it inside for winter.
Why is my red ti plant turning green?
Not enough light. The red, pink, and purple pigments need bright light to develop — move it somewhere brighter (but not harsh afternoon sun) and new leaves will color up.
🧰 Our favorite ti plant (kī) tools & supplies
What we actually reach for at the nursery:
- Rain barrel or catchment jug — fluoride-free water is the #1 fix for brown tips
- Rich potting mix + perlite — moisture-holding but free-draining, the ti sweet spot
- Clean hand pruners — for harvesting lāʻī and cutting propagation logs
- Balanced slow-release fertilizer — a light feeding keeps leaves big and glossy
- Spray bottle of neem oil — spider mite insurance for indoor ti
