Lucky bamboo (Dracaena sanderiana) care

Trees · easy-going to keep

Lucky bamboo (Dracaena sanderiana) wants medium to bright indirect light; no direct sun. Water it weekly. Grown in water: keep the roots covered, change the water every week or two, and use rainwater, filtered or tap water left standing overnight. It is unusually sensitive to the fluoride and chlorine in fresh tap water, which shows as burnt tips. Grown in compost: keep it evenly damp, and let only the top centimetre dry. Pot it in free-draining compost with grit or perlite. A weak balanced feed monthly in spring and summer; none in winter, and repot every 2 years. Humidity: room humidity is fine. Toxic to cats and dogs.

Lucky bamboo: the upright or spiralled green stems sold standing in a vase of pebbles and water. It is not a bamboo — it is a dracaena, in the asparagus family, and the resemblance is only in the jointed stem. That matters in a house with animals, because this is toxic to cats and dogs and true bamboo is not.

Quick facts

Watering a Lucky bamboo

Water weekly. Grown in water: keep the roots covered, change the water every week or two, and use rainwater, filtered or tap water left standing overnight. It is unusually sensitive to the fluoride and chlorine in fresh tap water, which shows as burnt tips. Grown in compost: keep it evenly damp, and let only the top centimetre dry.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright indirect light, and never direct sun — the leaves of a plant grown in water scorch faster than one in compost. It survives a dim corner, but pales and stops putting out new leaves.

Humidity and temperature

Room humidity is fine. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Free-draining is the whole requirement. Ordinary compost cut with a third perlite for the leafy kinds; cactus compost for the snake plants, which rot at the base if the mix holds water.

Feeding

A weak balanced feed monthly in spring and summer; none in winter. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot every 2 years. Every two or three years. Snake plants flower and grow best slightly potbound, so leave them until the pot is visibly straining.

Common problems

Brown tips on long thin leaves
Fluoride and salts in tap water — dracaenas are unusually sensitive.

Fix: Water with rainwater or filtered water, and flush the pot through a few times a year.
Soft yellow base on a snake plant, leaves falling out of the pot
Rot. Water has sat in the crown or the mix.

Fix: Take the firm leaves as cuttings and start again. Water snake plants from below or around the edge, never into the centre.
Lower leaves yellowing and dropping on a cane dracaena
Normal ageing if it is one at a time; overwatering if it is several.

Fix: Peel the old leaves off cleanly and check the mix is drying out between waterings.

Propagation

Leafy dracaenas: cut the cane into sections and root them upright in water or damp compost. Snake plants: divide the rhizome, or cut a leaf into 8 cm pieces and stand them the right way up in compost — note that a variegated leaf propagated this way comes back plain green, so divide instead if you want to keep the markings.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Toxic to cats and dogs. The saponins cause vomiting, drooling and — in cats specifically — dilated pupils. Not dangerous to people beyond an upset stomach.

Questions people ask

Can lucky bamboo live in water forever?

Yes, and most do. It will stay smaller and needs a drop of weak feed every couple of months, since pebbles hold nothing for it to eat. Moving it to compost makes it grow faster and larger, and it will not go back happily once it has rooted in soil.

Why are the leaves turning yellow?

Usually the water. Fluoride, chlorine and salts build up in a vase that is topped up rather than emptied, and this plant is more sensitive to them than most. Empty and refill rather than topping up, and use filtered or stood water. Yellow that starts at the stem base instead is rot, and that part will not recover — cut above it and re-root the green section.

Is lucky bamboo poisonous to cats?

Yes. Like other dracaenas it contains saponins, which cause vomiting, drooling and dilated pupils in cats. It is not usually dangerous beyond that, but a cat that chews it will be unwell. True bamboo, which this is often mistaken for, is not toxic.

How often should you water a Lucky bamboo?

Water weekly as a starting point — that is the cadence PlantParlour sets for Dracaena sanderiana. Grown in water: keep the roots covered, change the water every week or two, and use rainwater, filtered or tap water left standing overnight. It is unusually sensitive to the fluoride and chlorine in fresh tap water, which shows as burnt tips. Grown in compost: keep it evenly damp, and let only the top centimetre dry. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.
