A single well-chosen tree can carry a whole garden through October. Which maples earn their space, and how to plant one properly.
Every garden needs one tree that stops people mid-sentence. In a shaded garden, that tree is usually a maple — not because maples are fashionable, but because they do the one thing shade gardeners lack: they bring colour to the end of the season, when everything else is winding down.
Which maple?
For small gardens, Acer palmatum varieties are hard to beat: ‘Sango-kaku’ for coral bark in winter, ‘Bloodgood’ for deep purple through summer, ‘Osakazuki’ for the finest scarlet in autumn. For larger spaces, Acer japonicum ‘Aconitifolium’ is a quiet giant with extraordinary autumn colour. Avoid the fast-growing silver maples — beautiful, but they will outgrow a small garden within a decade.
Plant it properly, once
Dig a hole three times the width of the rootball and no deeper than it. Maples hate being buried deep: the root flare must sit at or just above soil level. Backfill with the excavated soil — no fertiliser, no compost in the hole — and mulch around, not against, the trunk. Water deeply through the first two summers, and then the tree is on its own.
Shelter from wind and late frost
Maples leaf early, and late frosts can scorch the new growth. A position with some shelter — a wall, a hedge, the north side of a building — protects both the leaves and the autumn display. Wind is the other enemy: it shreds the delicate foliage and hurries the leaves off the tree before they have finished colouring.
The autumn moment
For two or three weeks, the tree becomes the garden. Put a bench where you can see it against the low October light, and resist the urge to tidy the fallen leaves immediately. A carpet of red under a red tree is the whole point.
One good tree, planted once, cared for for ten years, will give more than a border full of annuals ever could. Choose it like you mean it.
