Ti plant care: watering, light and repotting
Also called cordyline, good luck plant · Cordyline fruticosa · Asparagaceae family
10 d in winter
How often to water the ti plant?
Allow about 6 days between waterings in spring and summer, and 10 days in autumn and winter, when growth slows down. These rhythms apply to a room with its favourite light: in a darker room the plant drinks less; in a brighter one, it drinks more.
Its bright colours need lots of light. Sensitive to fluoride and hard tap water.
Misting every 4 days helps keep the air humid around its leaves, especially in winter when central heating dries the house out.
What light does it need?
The ti plant likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Repotting and fertiliser
Repot every 2 years, ideally in April, into a pot only slightly bigger than the last one. As for fertiliser, from April to September, feeding every 30 days is enough; the rest of the year, let it rest.
Adult size: 2–5 ft (60 cm–1.5 m).
Toxic to pets and children. Keep this plant out of reach and, if it is eaten, contact a vet or a poison control centre.

Frequently asked questions
How often should you water the ti plant?
About every 6 days in spring and summer, and every 10 days in autumn and winter, in a room with its favourite light. The darker the room, the longer you wait between waterings. Before watering, check that the top inch of soil has dried.
Where should you put the ti plant?
The ti plant likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Should you mist the ti plant?
Yes, misting every 4 days does it good, especially in winter when heating dries the air. Use soft, room-temperature water.
When should you repot the ti plant?
Every 2 years, ideally in April, or sooner if roots come out of the drainage hole. Choose a pot only slightly bigger, 1 to 1.5 in (2 to 4 cm) wider, always with a hole in the bottom.
Cats, dogs, children: is the ti plant safe?
The ti plant is toxic to pets and to children if eaten. Keep the plant out of reach and, if it's eaten, call a vet or a poison control centre.
Is it an easy plant to care for?
Fairly: the ti plant needs a little attention, mostly with watering and light. Nothing complicated with a reminder at the right time.
These are guidelines for an indoor plant in a temperate climate. Trust the soil too: a finger pushed an inch into it will tell you whether it's thirsty.
