Frequently asked questions about the Acer Palmatum
Quick answers to the most common questions about winter hardiness, location, pruning and caring for the Japanese maple.
Is the Acer Palmatum winter hardy?
Yes, the Acer palmatum (Japanese maple) is hardy: in the open ground it withstands temperatures down to approximately -20°C. Is your Acer in a pot? Then the root ball is more vulnerable to freezing, so protect the pot extra well during severe frost.
How do I protect my potted Acer Palmatum from frost?
Wrap the pot (not the crown) during severe frost, for example with garden fleece or bubble wrap, so the root ball doesn't freeze through completely. If possible, place the pot on feet or against a sheltered wall, and keep the soil slightly moist, drying out can also cause damage in winter.
Where should I place my Japanese maple, sun or shade?
The Acer palmatum grows best in a spot with partial shade, sheltered from harsh midday sun and strong wind. Some cultivars with dark or finely cut foliage can tolerate a bit more sun, but avoid a full, hot south-facing spot without shelter for any type.
Why are the leaf edges of my Acer Palmatum scorching?
Scorched, shrivelled leaf edges are usually caused by a combination of harsh sun, wind and drought. Move the plant to a more sheltered spot and make sure it gets enough water, especially during warm, dry periods and for potted plants.
When is the best time to prune a Japanese maple?
Prune your Acer palmatum preferably in autumn or winter, when the tree is dormant. If you prune in spring, the tree often 'bleeds' sap heavily from the cuts. Limit pruning to removing dead, diseased or crossing branches, the Acer already has a beautiful natural shape.
Why do the leaves of my Acer Palmatum change colour in autumn?
Those spectacular red, orange and yellow autumn colours are actually one of the most beautiful traits of the Japanese maple! As the days get shorter and colder, the plant breaks down its leaf chlorophyll, revealing the underlying colour pigments.
Is the Acer Palmatum toxic to pets?
No, the Acer palmatum is generally considered non-toxic. Still, it's always wise to prevent pets and young children from eating or chewing on plants, to avoid irritation.
