About this plant
This tree has distinctive bark. It is shaggy, peeling and a pleasing warm-brown. A pleasant counterpoint to the silvers of so many birches. The tree has dark-green, toothed, leaves that take on yellow colour in autumn. It is early into leaf and makes a spreading plant which can achieve great heights over time. It lacks the poise and elegance of many birches but makes a good upstanding tree. It is tolerant of poor soil and can take dry conditions which are useful attributes. This can reach 30m (100ft) height in its native habitat of Northern China, Korea and Manchuria. A more normal size in Britain and Ireland would be 15m (50ft) height with 8m (26ft) spread.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water during drought
After three or four weeks without rain, except for drought tolerant plants, those in the ground often get stressed. Adopt the habit of deep-watering one section of the garden each day. Check plants in pots more frequently, especially in hot weather.
Encourage plants to develop good root systems by giving occasional deep watering. Some plants, such as conifers and heathers, do not show much sign of distress so water these if in doubt.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
