How to grow Snowy mespilus

Sunlight
Full sun to partial shade
Watering
Moderate; water through dry summers in the first few years
Soil
Moist, well-drained; dislikes shallow chalk
Soil pH
Acid to neutral

Planting

Plant in autumn or early spring. It is one of the best small trees for an average garden, usually grown as a multi-stemmed specimen. Avoid thin alkaline soils, where it becomes chlorotic and sulks.

Pruning

Very little needed. Thin out crossing or crowded stems in winter to keep the airy, open framework; hard pruning ruins the natural shape.

Propagation

Layering in autumn is the most practical amateur method. Seed germination is slow and erratic, and the hybrid does not come true.

Pests and diseases

Usually healthy. Fireblight can occasionally affect it, causing shoots to blacken and wilt suddenly as if scorched.

Value to wildlife

Early white flowers feed emerging bees, and the small purple-black summer fruits are stripped quickly by blackbirds and thrushes.

Notes

Three seasons of interest: white blossom against copper young foliage in April, summer berries, and orange-red autumn colour. Reliable and rarely disappointing, which is not something you can say about many small trees.
