About this plant
A striking conifer that makes a tall tree with a broad head that carries spreading and uplifted branches clad in dark green needles. It has small yellow pollen-cones that are followed by slender cone-shaped fir-cones that are generally in small downward-pointing clusters. These are green when young, maturing to brown and form an attractive feature. The tree is a native of Japan and Korea where it can attain a height of 40 metres, enjoying a warm, moist climate. It is often used as a subject for bonsai and is also an important timber tree. It is also tolerant of air pollution. There are many ornamental cultivars which are suitable for the gardener.

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 dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
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.
