Dahurian Larch, Kurile larch
Larix gmelinii
Family: Pinaceae
What it is like
Larix gmelinii is a deciduous Tree growing to 30 m (98ft 5in) at a slow rate. See above for USDA hardiness. It is hardy to UK zone 1 and is not frost tender. It is in flower from May to June, and the seeds ripen in October. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Wind. Suitable for: light (sandy) and medium (loamy) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure.
Height (m): 30

Resin is extracted by tapping the trunk. It is obtained from near the centre of the trunk, one properly made borehole can be used for 20 - 30 years. The resin has a wide range of uses including wood preservatives, medicinal etc. The hole is made in the spring and the resin extracted in the autumn. The yield is about 40 grams per tree. The bark contains tannin. Wood - hard, durable. Used in construction, water pipes, mine props, beams etc.
Resin: Used in perfumery, medicines, paints, soap making etc. This also includes turpentine, which is extracted from many resins and used as a preservative, water proofer etc,
Tannin: An astringent substance obtaied from plants, it is used medicinally, as a dye and mordant, stabilizer in pesticide etc.

How it is grown
Prefers an open airy position in a light or gravelly well-drained soil. Plants are intolerant of badly drained soils, but they tolerate acid and infertile soils. Succeeds on rocky hill or mountain sides and slopes. A north or east aspect is more suitable than west or south. This species is very cold-hardy when fully dormant, but the trees can be excited into premature growth in Britain by mild spells during the winter and they are then very subject to damage by late frosts and cold winds. Hybridizes freely with other members of this genus. The plant is cultivated for re-afforestation in Asia and is also used as an ornamental. Growth is normally slow in Britain with average height increases of less than 30cm per year. Open ground plants, 1 year x 1 year are the best for planting out, do not use container grown plants with spiralled roots. Plants transplant well, even when coming into growth in the spring. Plants in this genus are notably resistant to honey fungus.
Propagating it: Seed - sow late winter in pots in a cold frame. One months cold stratification helps germination. It is best to give the seedlings light shade for the first year. As soon as they are large enough to handle, prick out the seedlings into individual pots. Although only a few centimetres tall, they can be planted out into their permanent positions in the summer providing you give them an effective weed-excluding mulch and preferably some winter protection for their first year. Otherwise grow them on in the cold frame for their first winter and plant them out in early summer of the following year. The seed remains viable for 3 years If you are growing larger quantities of plants, you can sow the seed in an outdoor seedbed in late winter. Grow on the seedlings in the seedbed for a couple of years until they are ready to go into their permanent positions then plant them out during the winter.
