Acer palmatum dissectum 'Garnet' Tree

Acer palmatum dissectum 'Garnet' has feathery, heavily dissected foliage that resembles the colour of a garnet stone throughout the spring and summer. It holds its colour well compared to other Japanese Maples, before turning shades of scarlet for a striking display in Autumn.

Ideal for small gardens or growing in a pot, Acer palmatum 'Garnet' grows to just 2 x 3 metres in 20 years. This wonderful red Japanese Maple is suited to a sheltered position in dappled shade where it will create a stunning focal point or backdrop. It prefers slightly moist, well-drained acidic soil although lime can be tolerated

'Garnet' is a very popular variety of Japanese Maple tree so we have a range of sizes, grown either as a mound forming bush or with a clear stem, top grafted at either 90cm or 130cm. The larger specimens have been grown over many years into a lovely tiered shape and will create a stunning feature.

Planting Advice For Acer palmatum dissectum 'Garnet' Trees

Pot grown 'Garnet' Japanese Maples can be planted at any time of the year. Firstly, remove all weeds and grass within a metre of your desired planting hole then dig a square hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, we advise sprinkling root grow in the hole, especially if you have poor soil.

When planting Japanese Acers, use ericaceous compost when possible as this encourages vibrant foliage colour. Using 50% of the original soil and 50% compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems.

Watering & Aftercare Advice For Acer palmatum dissectum 'Garnet' Trees

If you’re planting in spring or summer, water well and regularly for the first few months. If you’re planting in autumn, you may only need to water your tree a little. It is important to keep an eye on young trees and increase watering if there are extended periods of hot or dry weather. 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.

Once planted, 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 dissectum 'Garnet' 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.

Below are definitions of various forms, which refer to the shape of the tree defined by the pruning it has received. For more advice, please contact us.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.

Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.

Bush: A plant with many stems low down, rather than one clear stem.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branch), which supports a branched crown. Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height.

Standard  either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard  10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard  12-14cm girth, approximately 3.5-4.5m in height
Extra Heavy Standard 14-16cm girth approximately 4.0-6m in height

The table below gives sizes and forms available for this variety, along with photos you can enlarge (these are only a guideline as all plants are unique so vary).
