Acer Palmatum Koto Ito Komachi will thrive in soil that is

• Nutrient rich
• Free draining
• Acidic

Plant Acer 'Koto Ito Komachi' in morning sun to part shade.

Its very fine foliage makes it more vulnerable to scorching than tougher, broad-leaved trees, so shelter is particularly important.

For Canterbury gardens, look for a position offering:

Morning sunlight
Protection from intense afternoon heat
Shelter from hot nor'west winds
Consistent soil moisture
Good drainage

Filtered light beneath taller trees can also work beautifully, provided there isn't excessive competition for water.

Water deeply and regularly during the first couple of growing seasons while the root system becomes established.

Pay particular attention during the first summer and during periods of hot, drying wind.

Once established, continue watering during prolonged dry periods.

Japanese Maples have relatively shallow root systems and perform best where soil moisture remains reasonably consistent.

Allowing the tree to become extremely dry and then giving it a bucket of water once the leaves have already crisped up isn't quite the same thing.

Apply a layer of organic mulch around the root zone each year.

Mulching helps:

Retain soil moisture
Keep roots cooler through summer
Reduce weed competition
Improve soil structure
Protect the shallow root system

Keep mulch slightly away from the trunk and graft union.

Apply a balanced slow-release fertiliser in spring as new growth begins.

Japanese Maples generally don't require heavy feeding.

Avoid excessive nitrogen fertiliser, which can encourage overly soft, vigorous growth that is more susceptible to wind and weather damage.

An annual application of compost around the root zone is also beneficial.

Very little pruning should be required.

Koto Ito Komachi naturally develops an attractive fine-branched structure, so allow the tree to establish its own form.

Prune selectively to:

Remove dead or damaged branches
Remove crossing or rubbing growth
Thin congested branches where necessary
Improve the framework while young
Remove unwanted growth below the graft

Avoid hard or repetitive clipping.

Leaf Scorch and Canterbury Nor'westers

The fine foliage is one of the reasons we love Koto Ito Komachi – but it also means this isn't the Japanese Maple we'd choose for the most exposed corner of the property.

Brown or crispy leaf tips can be caused by:

Hot nor'west winds
Intense afternoon sunlight
Dry soil
Containers drying out
Excessively exposed positions

This is generally environmental leaf scorch rather than disease.

Shelter, mulch and consistent watering will make a significant difference to how good the foliage looks through summer.

Acer 'Koto Ito Komachi' is frost hardy once established and is well suited to cooler New Zealand climates.

After producing its autumn colour, the foliage falls and the tree becomes dormant through winter.

The main frost risk occurs when tender new leaves emerge in spring. A particularly late frost can damage fresh growth, although established trees normally recover.

The compact size and delicate foliage make Koto Ito Komachi an excellent candidate for large container growing.

Choose:

A substantial container
Excellent drainage
Premium-quality potting mix
A sheltered position
Regular watering through summer

Containers can dry out surprisingly quickly during Canterbury's hot and windy weather, so check the potting mix regularly rather than relying on rainfall.

As the tree matures, occasional repotting or root maintenance may be required.
