Japanese maples burst with glorious colour

Spectacular, dramatic, fantastic in a border and loved for their delicate colourful foliage – ranging from green, yellow, orange, red and purple

What’s in a name?

Japanese maple is the common name used to describe all Acer palmatum varieties.Acer’ means ‘sharp’, and  ‘palmatum’ refers to the leaf shape, which is palm or hand-shaped with five pointed fingers. The name Acer palmatum is usually followed by the name of the variety, which is written in inverted commas, for example Acer palmatum ‘Crimson Queen’.

Let them thrive

Contrary to popular belief, Japanese maples are not acid-loving trees that need ericaceous compost. They grow in any medium as long as moisture and oxygen are available to the roots. They’ll even grow in pure gravel providing they’ve got the right amount of moisture. Ericaceous

compost is too heavy for their roots and may cause water logging, which will ultimately lead to a tree that fails to thrive.

The perfect soil pH for a Japanese maple is 6.5 – just the acid side of neutral.

What about the weather?

We’ve often heard our customers say, “but they don't like the sun and they need shelter from the wind”, and yet Japanese maples have survived and thrived in the wild with these conditions for thousands of years.

Generally, a Japanese maple with red, purple or dark green foliage needs sunshine for at least half of each day to keep its colour. Variegated, white, pale, vivid yellow or lime-leaved varieties need bright dappled shade. Wind can dry the soil or compost, if planted in a pot, so each needs an even amount of moisture to be maintained at its roots.

What about maintenance?

Plant or re-pot your Japanese maple at any point in the

growing season up to August. The best time is when the buds are about to break and the maple is full of vigour. The later you leave it, the more you risk the foliage quality deteriorating.

Japanese maple are best pruned from late February to mid August only. They may bleed some sap when they’re pruned, but this is generally not a problem for the tree.
