Acer palmatum 'Trompenburg' Tree

A fantastic tree for small gardens, Acer palmatum 'Trompenburg' has deeply pinnate foliage with rolled edges making it stand out amongst other Acer trees. The unusual narrow foliage is purple/red in the spring, fading to green in the summer and then boasting orange/red autumn colours.

Acer palmatum 'Trompenburg' will grow into a small tree or large shrub with a rounded form. Growing to just 4 x 4 metres in 20 years, it is an ideal choice when space is limited or you want to grow it in a large container. Best positioned in a moist but well drained soil in slight shade, 'Trompenburg' is tolerant of full sun but partial shade is recommended for the best foliage colour.

Planting Advice For Acer palmatum 'Trompenburg'

Our pot grown Trompenburg Japanese Maples can be planted at any time of the 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 'Trompenburg'

Trompenburg 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 'Trompenburg'

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.
