Description
An upright, columnar Mountain Ash tree, the award-winning Sorbus aucuparia ‘Autumn Spire’ is especially good for smaller spaces or gardens. Vivid autumn colour makes for a striking feature, with the red autumn foliage contrasting wonderfully with the bright yellow berries. This eye catching juxtaposition is not missed by British birds who feast on the fruits. As well as the colourful autumnal display, the Sorbus Autumn Spire tree also produces pretty white flowers in late spring/early summer.
Sorbus aucuparia ‘Autumn Spire’ will grow in many difficult situations including polluted and exposed areas, although avoid wet or waterlogged sites. Growing to 4 x 1 metres in 20 years, this upright Rowan is great for making the most of vertical space. A very attractive tree with an array of colourful features that make it a magnet to wildlife.

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
Rowan 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.
Rowan trees require a strong framework to support their many berries, so it is good to encourage this by raising the crown in summer. Simply prune the lower branches and any crossing, damaged or diseased branches within the crown. Hard pruning can be carried out in the dormant season, from autumn to winter.
