How to plant it

General steps for this plant. Save a garden and these become specific to your location, soil and light.

  1. Step 1When to plant

    Plant during November to March, whenever the ground is not frozen or waterlogged.

    Woody plants establish best planted while dormant, so roots grow before the first summer.

  2. Step 2Where to put it

    Choose sun or shade — this plant tolerates both. Allow 5 m of room around it — mature spread is 5 m and mature height 5–10 m.

    Light in your garden is not answered, so this is the plant's own requirement.

  3. Step 3Preparing the ground

    Dig a hole twice as wide as the root ball and no deeper, loosen the sides, and plant so the top of the root ball is level with the surrounding soil.

    Soil is not answered. This plant grows in average, moisture-retentive conditions.

  4. Step 4Watering while it establishes

    Water thoroughly at planting (20–30 litres), then only when the top few centimetres of soil are dry, through the first two full growing seasons.

    Even a drought-tolerant plant (3/5 here) only becomes drought-tolerant once established.

  5. Step 5Mulch

    Spread 5–7 cm of composted bark or garden compost around the plant, keeping it clear of the stem.

    Mulch cuts water loss and suppresses weeds through the first summer, when losses are most likely.

  6. Step 6The first year

    Check it after strong wind and in long dry spells. Little else is needed.

    Maintenance level on the plant record is low.

  7. Step 7What to watch for

    Struggles in hot, dry, compacted city soil. Toxicity: mild. Site it accordingly if children or pets use the space.

    Taken from the plant record and your measured climate figures, not from a general description.

Spacing: about 5 m apart — roughly 1 plant for every 10 m² if planted as a group.

What this guide could not use

  • No location saved, so planting times are general rather than local.
  • Soil moisture is not answered, so soil preparation is general advice.
  • Light is not answered, so the position below is the plant's own preference.
  • Whether you can water is not answered, so watering assumes hand watering.

Sorbus aucuparia, commonly called rowan (, also UK: ) and mountain-ash, is a species of deciduous tree or shrub in the rose family. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It flowers from May to June in dense corymbs of small creamy-white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species.

These figures come from the demonstration dataset kept for testing and as a fallback when the measured climate service is unavailable. They are representative, not observed, and are never presented as validated live data.
