How to Care for your Brachychiton Rupestris (Queensland Bottle Tree)

The Brachychiton Rupestris, more commonly known as the Queensland Bottle Tree, is an architectural wonder with a striking, swollen trunk that stores water like a built-in reservoir. Native to Australia, this slow-growing tree is as sculptural as it is resilient—making it a favorite for both interior statement pieces and xeriscaped gardens.

With the right light and care, this drought-tolerant beauty can thrive indoors for decades. Here's how to keep yours healthy and happy.

Light Requirements

• Prefers bright, indirect light, but can tolerate some direct sun.

• In low light, growth will slow significantly and the trunk may soften.

• Rotate every few weeks to encourage even growth and trunk development.

Watering Schedule

• Spring to Fall (active growth): Water every 2–3 weeks

• Winter (dormant season): Water every 4–6 weeks

• Let soil dry out completely between waterings—this tree is built for drought.

How Much to Water

• For a 10–12” pot, start with 8–12 oz (240–355 ml) of water

• Always check that the soil is dry several inches down before watering again

• Avoid letting water sit in the bottom of the pot

Fertilizer Tips

• Fertilize lightly during spring and summer with a diluted balanced fertilizer (half strength is fine)

• No fertilizer needed in fall and winter

Trimming & Pruning

• Minimal pruning required—remove dead or yellowing leaves as needed

• If shaping is desired, trim during the growing season

• Always use clean, sharp tools to avoid damaging the trunk

Common Issues

• Soft trunk: Overwatering or root rot—cut back immediately

• Leaf drop: Often seasonal or caused by stress (light change, drafts)

• Brown spots: Can indicate fungal issues or sun scorch—adjust lighting and airflow

Repotting Notes

• Repot every 3–4 years, or when rootbound

• Use a gritty, well-draining mix (like cactus or succulent soil)

• Ensure pot has excellent drainage

Lifespan & Growth

With proper care, the Queensland Bottle Tree can live for 50–100 years. Indoors, it typically grows 4–6 feet tall, though older specimens can reach even greater heights in ideal conditions.
