Begonia curtisii 'Galaxy' Care Guide

Light Requirements

Begonia curtisii 'Galaxy' thrives in bright, indirect light. Position it near an east or north-facing window, or slightly back from a brighter south or west-facing window.

Avoid direct sunlight, particularly during the middle of the day, as this can scorch the delicate foliage and cause fading of the silver markings.

Ideal Light: Bright indirect light

Watering

Keep the soil lightly moist but never waterlogged. Allow the top 2–3cm of soil to dry slightly before watering again.

Begonias dislike sitting in wet soil, which can quickly lead to root rot and rhizome damage. During winter, reduce watering frequency as growth slows.

Always water around the base of the plant rather than directly onto the leaves, as wet foliage can encourage fungal issues.

Top Tip: It's better to underwater slightly than overwater.

Humidity

This begonia enjoys elevated humidity levels and performs best in environments with humidity above 60%.

Low humidity can result in brown leaf edges, crisping, or reduced growth.

Ways to increase humidity:

• Use a humidifier nearby
• Grow within a terrarium or display cabinet
• Group with other tropical plants
• Place on a pebble tray filled with water

Avoid misting directly onto the foliage as prolonged moisture can encourage mildew and leaf spotting.

Temperature

Begonia curtisii 'Galaxy' prefers warm, stable temperatures.

• Ideal range: 18°C–26°C
• Minimum temperature: 15°C

Keep away from cold draughts, radiators, and sudden temperature fluctuations.

Soil Requirements

A light, airy, free-draining growing medium is essential.

A suitable mix may contain:

• High-quality houseplant compost
• Perlite
• Orchid bark
• Coco coir or leaf mould

Good drainage helps prevent root and rhizome rot while allowing adequate airflow around the roots.

Feeding

Feed every 2–4 weeks during spring and summer using a balanced liquid houseplant fertiliser at half-strength.

Reduce feeding during autumn and stop altogether through winter when growth naturally slows.

Growth Habit

This is a rhizomatous begonia that spreads horizontally via thick creeping rhizomes. New leaves emerge from the rhizome and gradually form a dense, attractive mound of foliage.

Given suitable conditions, plants will steadily expand and can be divided to create additional specimens.

Flowering

Although primarily grown for its foliage, mature plants may occasionally produce clusters of small pale pink to white flowers.

The blooms are delicate and attractive but are generally secondary to the spectacular leaves.

Pruning & Maintenance

Remove:

• Yellowing leaves
• Damaged foliage
• Spent flower stalks

Regular grooming helps improve airflow and encourages fresh growth.

Repotting

Repot every 1–2 years or when the rhizome begins to outgrow its container.

Choose a pot only slightly larger than the current one, as begonias generally prefer to remain somewhat snug in their containers.

Propagation

Begonia curtisii 'Galaxy' can be propagated through:

• Rhizome division
• Leaf cuttings
• Petiole cuttings

Propagation is best carried out during spring or early summer when active growth is strongest.

Common Problems

Yellow Leaves

Usually caused by:

• Overwatering
• Poor drainage
• Cold temperatures

Crispy Brown Edges

Often indicates:

• Low humidity
• Inconsistent watering
• Excessive direct sunlight

Powdery Mildew

Can occur if airflow is poor or humidity is excessively high without ventilation.

Improve airflow and remove affected leaves promptly.

Root Rot

Typically caused by:

• Waterlogged compost
• Poor drainage
• Overwatering

Always ensure excess water can drain freely from the pot.

Is Begonia curtisii 'Galaxy' Pet Safe?

No. Like other begonias, Begonia curtisii 'Galaxy' is considered toxic to cats, dogs, and other pets if ingested. Keep out of reach of curious animals.
