About Shohin Japanese Maple
Acer palmatum 'Kiyohime' · also called Kiyohime Japanese Maple · flowering
Acer palmatum 'Kiyohime' is a compact, dwarf Japanese maple with short internodes and a naturally low, spreading habit, making it a classic shohin and small-bonsai subject. It leafs out fresh green with reddish margins and colours warmly in autumn. It demands sheltered light, steady moisture and a hard winter rest to thrive.
Preferred mix: Free-draining, slightly acidic bonsai mix
Watch for — Leaf scorch: Brown, crispy margins from too much sun, wind or under-watering. Move to morning sun and afternoon shade and keep the rootball evenly moist.
Why shohin japanese maple needs this mix
Shohin Japanese Maple is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Shohin Japanese Maple evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons shohin japanese maple struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of shohin japanese maple — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing shohin japanese maple in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for shohin japanese maple?
Shohin Japanese Maple likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "herb" or "Mediterranean" mixes are usually fine for shohin japanese maple, but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so shohin japanese maple needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for shohin japanese maple covers the timing and technique step by step.
