Japanese Maple Care

How To Care For Japanese Maple Trees (acer palmatum)

Although beautiful and delicate looking, Japanese Maple trees surprisingly require very little care.

The only annual task that benefits the plant is a mulch around, but not touching, the stem. Use well-rotted compost and apply it in early Spring.

The key dangers faced by Japanese Maples are damage by late spring frosts and water-logging. Frosts can damage the leaves, especially those of Dissectum varieties but it is only rarely fatal. Simply snip off badly damaged areas of the leaves and the plant will recover in a month or so.

Water logging is most likely to damage the fine root system in winter. There is no cure, so ensure that the planting position is chosen well (see planting Japanese Maples in the navigation bar above).

How To Prune Japanese Maple Trees
Japanese Maple trees are fine without any pruning, they will form their natural shape with no need for your intervention.

They do appreciate a bit of help though when the central area becomes over-crowded. This can stop air circulating and make the trees more prone to fungal diseases. Every two or three years when the leaves have fallen, prune out any diseased or damaged wood. If the central part of the tree looks overcrowded, prune some of the stems and smaller branches, but maintain the overall shape of the tree.

Message: My 20-year old acer palmatum seems to be dying. Half of it died last year and most of the rest has had brown crispy leaves since early August this year. Should I give it another chance or chop it down? And will it be safe to replace it with another acer or possibly a flowering cherry?

Message: I have 2 trees that have done well within the garden flowers where they are both planted. The only concern is roots uplifting on both trees. What should I do to cover the roots and prevent water runoff.Just putting earth on or around roots doesn't work well.

Message: Hi, I bought an Acer Palmatum Dissectum and have planted it in a patio pot, although roughly 15 healthy looking leaves have fallen off in a few days! Two leaves which are still attached have also shrivelled up in 2-3 days. I am watering regularly but am not sure what is happening to it! Please advise! Ta!
