Introduction

In this bonsai care guide we take a look at the Azalea bonsai trees, Azalea Bonsai (Rhododendron spp.) are among the most prized flowering bonsai species, known for their stunning spring blooms that come in various colours including pink, red, white, and purple. Popular varieties include Satsuki Azalea and Kurume Azalea, which are favored for their small leaves, compact growth, and ability to flower profusely.

Due to their sensitivity and specific care requirements, azaleas are better suited to experienced bonsai keepers who can provide consistent attention to watering, soil pH, and root care.

🧪 Care Essentials

🌞 Light
Azaleas prefer bright, indirect light or dappled sun. Too much direct sun can scorch delicate leaves and flowers, especially during hot summers. Ideal placement is morning sun with afternoon shade.

💧 Watering
Keep soil consistently moist—azaleas do not tolerate drying out. Use rainwater or distilled water when possible, as they are sensitive to hard tap water and prefer slightly acidic conditions.

🌿 Soil
Use an acidic, well-draining bonsai soil, such as a mix containing kanuma (a Japanese soil for acid-loving plants). Avoid alkaline soils, as they can lead to leaf yellowing and poor flower production.

🌾 Fertilizer
Feed with a low-nitrogen fertilizer designed for acid-loving plants during the growing season. Avoid fertilizing while in bloom. Use organic pellets or liquid feed monthly from spring to early autumn.

🪴 Repotting
Repot every 2–3 years, preferably after flowering in late spring or early summer. Do not disturb the roots too aggressively—azaleas have fine, sensitive roots. Always use fresh acidic soil when repotting.

✂️ Pruning & Shaping
Prune after flowering to shape the tree and encourage compact growth. Avoid pruning in late summer or autumn, as this may remove flower buds. Azaleas respond well to wiring, but their branches can be brittle—wrap with care and check regularly.

⚠️ Common Problems & Fixes

Problem	Likely Cause	Fix
Leaf yellowing	Alkaline soil or hard water	Use acidic soil and rainwater/distilled water
Bud drop	Dry soil or sudden temperature shifts	Maintain consistent watering and protect from cold drafts
Root rot	Poor drainage or overwatering	Repot with free-draining acidic soil; reduce watering slightly
