Architectural and undemanding, the dracaena — whether the spiky dragon tree or the broad-leaved corn plant — grows on a single cane and asks for bright filtered light and a drink only when the surface dries. It is unusually fussy about water quality: fluoride and salts in tap water scorch the leaf tips. Keep it warm, and note it is toxic to cats and dogs.

Care at a glance

Light
Bright, filtered light; tolerates medium lightCopes with some shade but grows leggy and loses its leaf markings; direct sun scorches. Variegated forms want the brightest filtered spot.
Water
When the top few centimetres of compost dryRoughly every 1–2 weeks in summer, less in winter. Use rainwater or filtered water — it is sensitive to fluoride and salts.
Soil
Free-draining loam-based or multipurpose mixAdd perlite or grit; the cane base rots in compost that stays sodden.
Humidity
Moderate humidity preferredAverage rooms are fine, but very dry air worsens brown leaf tips.
Temperature
Ordinary room temperatures, 18–24 °C (64–75 °F)Keep above 13 °C (55 °F); cold draughts brown and drop the leaves.
Difficulty
EasyTolerant and slow to complain — the main quirk is its dislike of fluoridated tap water.
Pets
Toxic to petsToxic to cats and dogs — contains saponins causing vomiting (sometimes with blood), drooling, and loss of appetite; cats may show dilated pupils (ASPCA).

Propagation

Dracaenas are propagated from stem (cane) cuttings, which is also how you control their height. Cut the leafy top off a tall cane and root it in water or damp compost as a 'top cutting'; it forms roots over several weeks and carries on growing.

The bare cane left behind isn't wasted: cut it into 10–20 cm sections, keep them the right way up (mark the top), and stand them in damp gritty mix. New shoots sprout from buds along the cane, and the original stump usually resprouts below the cut, giving you a bushier plant.

Common problems

  • Brown leaf tips with a yellow halo

    Likely cause: The classic dracaena issue: a sensitivity to the fluoride and mineral salts that accumulate from tap water, made worse by erratic watering that lets the rootball parch.

    Fix: Water with rainwater or filtered water, flush the pot occasionally to wash out salts, and keep watering even. Trim brown tips to shape.

  • Lower leaves yellowing and dropping

    Likely cause: Often natural — dracaenas shed older lower leaves as the cane grows. Excess can mean over- or under-watering.

    Fix: A steady loss of the oldest leaves is normal; if many drop fast, review your watering and warmth.

  • Soft, mushy base or cane

    Likely cause: Root or stem rot from compost kept too wet, especially in a cold room.

    Fix: Cut back to firm tissue, let it dry, and re-root the healthy top; discard a rotten cane base.

Frequently asked questions

Which dracaena do I have — a dragon tree or a corn plant?

Dracaena marginata, the dragon tree, has thin, stiff, red-edged leaves in spiky tufts on slender canes. Dracaena fragrans, the corn plant, has broad, soft, often centre-striped leaves like a maize plant. Both share the same care.

Why does my dracaena have brown tips no matter what I do?

Dracaenas are notably sensitive to the fluoride and soluble salts in tap water, which accumulate and burn the leaf tips. Switching to rainwater or filtered water and flushing the pot monthly usually stops new tips from browning.

How do I shorten a leggy dracaena that has lost its lower leaves?

Cut the cane at whatever height you want with a clean saw or secateurs. The stump resprouts new shoots just below the cut, and you can root the removed top as a separate plant — so one tall, bare cane becomes two bushy ones.

Is lucky bamboo a kind of dracaena?

Yes — lucky bamboo is Dracaena sanderiana, not a true bamboo, and shares the genus's saponin toxicity to pets. Its care differs because it is usually grown in water, which we cover on its own page.
