About Full Moon Maple

Acer shirasawanum 'Aureum' · also called golden full moon maple · flowering

Golden full moon maple is a slow, refined deciduous tree with rounded, fan-pleated chartreuse-gold leaves that glow through summer and flush orange-red in autumn. Unlike palmate Japanese maples its foliage holds bright golden colour well, but only in dappled light. It needs shelter, even moisture, and free-draining acidic soil to avoid scorch.

Comfort temperature: -20 to 30°C

Watch for — Sun scorch and bleaching: The golden leaves burn and fade in strong sun. Plant in dappled shade with shelter from wind, and keep soil evenly moist to reduce stress.

The exact light full moon maple needs

Full Moon Maple wants bright, indirect light — lots of it, but filtered or off to the side, not the harsh midday sun that scorches its leaves.

Put a number on it — this is what a meter (or a free phone light-meter app) should read where full moon maple sits:

In plain terms, A few feet back from a south or west window, or right beside a bright east window. A sheer curtain over a sunny window is close to perfect: lots of light, no direct beam burning the leaves. Hours of unfiltered midday sun directly on the leaves (scorch), and dim back-of-room corners (slow decline). It is the both-extremes plant.

Signs full moon maple is getting too much light

The most exposed leaves show it first. For full moon maple specifically, watch for:

Light damage does not heal — a scorched leaf stays scorched — so the fix is to move full moon maple out of the harsh light rather than wait for it to recover.

Signs full moon maple is not getting enough light

Too little light is slower and sneakier than too much. The classic tell is etiolation: the plant stretches and pales as it reaches for a window. For full moon maple, look for:

If full moon maple is stretched, leggy and pale, our guide to leggy, stretched plants covers how to fix it and whether it can be pruned back into shape. Confusing "bright indirect" with "any bright room". Full Moon Maple needs to actually see a lot of sky — a sunless north wall or a deep corner is far too dim, even if the room feels light to you. The opposite mistake is parking it in raw afternoon sun, which scorches it within days.

Where to put full moon maple: the best window and room

The sweet spot for full moon maple is the band of bright light just out of the direct beam: a metre back from a south/west window, immediately beside an east window, or behind a sheer curtain on a sunny window. Rooms with a single small north window are usually too dark for it to do well long-term; a bright bathroom or a plant stand near (not in) a sunny window suits it far better.

  1. Find a bright but shielded spot. For full moon maple, the ideal is a metre back from a sunny window, beside an east window, or behind a sheer curtain — bright, but no direct beam on the leaves.
  2. Check for the shadow test. Hold a hand where the plant sits: a soft, fuzzy shadow means bright indirect (good); a hard, sharp shadow means direct sun (scorch risk); barely any shadow means too dim.
  3. Shield from harsh afternoon sun. If the only bright window gets fierce afternoon sun, add a sheer curtain or step full moon maple back a couple of feet rather than into a dark corner.
  4. Re-place it each season. Move full moon maple closer to the glass for the dim winter months and back again in spring — same spot, very different light.

Does full moon maple need a grow light?

Full Moon Maple responds well to a grow light if your home is dim: a mid-power full-spectrum LED about 30–45 cm above the plant, run 10–12 hours a day, comfortably stands in for the bright window it is missing — a useful fix for north-facing flats.

The seasonal light shift (why winter changes everything)

Winter light is a fraction of summer's, even at the same window. A full moon maple that is perfect a metre back from the glass in July may need to move right up to the window from November to February. The bonus: weak winter sun rarely scorches, so a spot that is too harsh in summer can become ideal in winter — and vice versa.

Light and watering are linked: a plant in weaker winter light photosynthesises and drinks far less, so the same routine that worked in summer can rot it. See how often to water full moon maple for the season-by-season schedule that pairs with this light plan.

Full Moon Maple light requirements — frequently asked questions

How much light does full moon maple need?

Full Moon Maple needs Roughly 400–800 fc — genuinely bright, but indirect. Around 4,000–8,000 lux: bright shade, the light a metre or so off a sunny window. A few feet back from a south or west window, or right beside a bright east window. A sheer curtain over a sunny window is close to perfect: lots of light, no direct beam burning the leaves.

Can full moon maple survive in low light?

No, not really. Full Moon Maple is a bright-light plant — in low light it etiolates: it stretches, pales, weakens and slows right down. It will not instantly die, but it steadily declines and never looks its best.

What are the signs full moon maple is getting too much light?

Bleached, faded patches and dry, brown, papery scorch where direct sun strikes full moon maple — the burn does not recover, so move it rather than wait. Crispy leaf edges and tips on the most sun-exposed side while shaded leaves stay green. Curling or cupping leaves angling away from an over-bright window. Confusing "bright indirect" with "any bright room". Full Moon Maple needs to actually see a lot of sky — a sunless north wall or a deep corner is far too dim, even if the room feels light to you. The opposite mistake is parking it in raw afternoon sun, which scorches it within days.

What are the signs full moon maple is not getting enough light?

New leaves come in small, pale and widely spaced as full moon maple etiolates, stretching toward the light. Leggy, drawn-out growth, loss of any variegation or rich colour, and a thin, reaching habit. Lower leaves yellow and drop while the plant prioritises the few that get light. If you see this, move full moon maple closer to the light or add a grow light — and check our guide on leggy, stretched plants.

Does full moon maple need a grow light?

Full Moon Maple responds well to a grow light if your home is dim: a mid-power full-spectrum LED about 30–45 cm above the plant, run 10–12 hours a day, comfortably stands in for the bright window it is missing — a useful fix for north-facing flats.
