Acer palmatum 'Osakazuki' Tree

Many believe Acer palmatum 'Osakazuki' has the most intense, long lasting red autumn colour of all Japanese Maples. The larger than average, seven lobed leaves are green in spring and summer, transforming into a blaze of fiery scarlet red in autumn.

An award-winning Japanese Maple, Acer palmatum 'Osakazuki' is ideal for the smaller garden, yet still capable of creating autumnal drama in a large garden. 'Osakazuki' is a fairly fast growing small tree / large shrub as a young specimen, settling down in maturity with an expected maximum height and spread of 4 x 3 metres in 20 years. It has an attractive open habit and prefers a slightly sheltered position in partial shade.

Japanese Maple 'Osakazuki' is one our top selling varieties due to its autumn colour and is offered in a range of sizes from quality young plants through to stunning large mature specimen trees.

Planting Advice For Acer palmatum 'Osakazuki' Trees

Our pot grown Osakazuki Japanese Maples can be planted at any time of year. Remove all weeds and grass within a metre of the planting site, then dig a square hole as deep as the root mass and approximately twice as wide. We recommend sprinkling root grow in the hole to help Japanese Maples establish more effectively, especially if the soil is poor.

Remove the pot and place the root mass in the planting hole so that the surface is flush with the surrounding ground. Using 50% of the original soil and 50% compost, fill in the hole and firm around gently. Use ericaceous compost when possible as this encourages vibrant foliage colour in Japanese Maples.

Finish by watering generously around the base. The tree planting guide has further information and videos.

Watering & Aftercare Advice For Acer palmatum 'Osakazuki' Trees

Japanese Maples require a good watering regime for the first couple of years by watering well and regularly throughout spring and summer. Increase in periods of hot or dry weather. If planting in autumn, you may only need to water a little. If possible, use rain water instead of tap water as this is more acidic and better for foliage colour. We stock a range of irrigation kits for more effective watering.

Keep the area free of competing weeds and grass for the first couple of growing seasons. If there is snow fall, gently brush the snow from the branches to ensure it does not weigh down the framework and cause damage.

Pruning Advice For Acer palmatum 'Osakazuki' Trees

Pruning should be carried out in the dormant season (November to March) as Japanese Maples bleed during other times of the year, which can weaken the branches. Japanese Maples rarely need pruning as their natural shape is normally the most attractive. Any pruning should be carried out with a less is more approach, only removing crossing, damaged or diseased branches.
