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 red 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 2 x 3 metres in 20 years. This wonderful red Japanese Maple will create a stunning focal point or backdrop. It is suited to a sheltered position in dappled shade and prefers slightly moist, well-drained acidic soil although lime is tolerated.

Acer palmatum dissectum 'Garnet' is a very popular variety of Japanese Maple tree so we provide a range of sizes, grown either as a mound forming bush or top grafted onto a clear stem. 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 Japanese Maples 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. 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.
