About Acer capillipes
Acer capillipes · also called Red Snakebark Maple · flowering
Red snakebark maple is a small deciduous tree grown for its green bark striped with white, vivid coral-red young shoots and leaf stalks, and orange-to-red autumn colour. Drooping clusters of small greenish flowers give way to winged samaras. Its year-round bark interest and compact size make it a fine specimen for smaller temperate gardens.
Preferred mix: Fertile, moisture-retentive, well-drained loam
Watch for — Leaf scorch: Foliage browns at the edges in hot sun, wind or dry soil; site in dappled shade with shelter and keep the rootzone consistently moist.
Why acer capillipes needs this mix
Acer capillipes hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Acer capillipes comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons acer capillipes struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for acer capillipes — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets acer capillipes dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for acer capillipes?
Acer capillipes prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
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
A good peat-free houseplant compost works for acer capillipes straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh acer capillipes's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for acer capillipes covers the timing and technique step by step.
