February rolls around, and while most of the is still in its winter slumber, it's a good opportunity to focus on Japanese maples.

These trees capture the eye in any green space with their delicate branches and . But timing matters to keep them looking their best.

Weed control is the most important task for trees, especially when young and newly planted.

This involves keeping the area around the tree's base clear of competing weeds to ensure the tree has access to sufficient water and nutrients for proper root development.

However, is also worthwhile for Japanese maples to maintain their health, shape, and beauty.

It also encourages new growth and improves airflow, which can help prevent disease.

The Royal Horticultural Society advises trimming Japanese acers when they are "fully dormant" in late autumn or winter. No "routine" pruning is required, the focus should be on plucking out dead, damaged, or crossing branches.

Ned Cromack, arborist and founder of The Bath Tree Company noted that waiting too long can be detrimental to users.

He told Woman & Home: "Any other time of year will cause the sap to bleed, which makes the healing process more difficult and can make the trees more susceptible to disease. This means that February is your last chance to tidy yours up if it needs it."

The easiest way to know what to remove from Acers is to identify leggy growth that has become too long for the space. Ned suggests trimming any twigs that appear supersized in comparison to the rest of the canopy.

He said: "Always aim to take as little off as possible to lessen the stress on the tree - you can always remove more the following year."

A safe approach to pruning Japanese acers in February is to avoid cutting into live tissues. Focus on removing grey dead twigs over winter, but do not cut the live bark.

Gardeners should know to avoid pruning in temperatures below zero, as this can cause frost damage.
