Description
Acer rubrum is the definitive Red Maple tree, renowned for its fantastic autumn colour. Green leaves are tinged with red in spring. In autumn, foliage takes on vibrant yellows and reds.
Acer rubrum is one of the most widespread trees of eastern and central North America but more than happy grown in a UK climate, tolerating most soil types and a wide array of planting conditions. An ideal specimen tree for a larger garden, this Red Maple will form a slightly pyramidal crown when young which becomes more rounded as it matures. In 20 years you can expect an approx. height and spread of 12 x 8 metres.

Planting Steps
1Preparation
- Pot-grown plants can be planted at any time of year, whereas bare roots need to be planted between November and March.
- Clear weeds and grass within a metre of the planting hole.
- Dig a hole as deep as the root mass and twice as wide.
- To help your plant establish more effectively, sprinkle Rootgrow in the hole.
2Planting
- Gently loosen the roots and place into the planting hole.
- Ensure the top of the plant’s compost is flush with the level of the surrounding soil and the graft union or collar of the tree is above ground level.
- Mix 50% of the original soil with 50% compost.
- Fill in the hole, firming the soil gently.
3Last Steps
- Water generously around the base of the plant.
- If you are planting either a single stem tree or mature standard tree, we recommend adding a staking kit and rabbit guard.
Aftercare Advice
Trees and shrubs require a good watering regime for a couple of years whilst they establish. Water well and regularly through spring and summer, increasing in hot or dry weather. If planting in autumn, you may only need to water a little. It is advisable to keep the area free of competing weeds and grass during this period.
