Pinus Parviflora | Japanese White Pine

Japanese White Pine is one of the most popular outdoor, evergreen conifers for bonsai and has been used for centuries in both China and Japan. It is an elegant, upright tree with deeply fissured, greyish bark. Soft needles, none in tufts of five, are tree-blue on the outer surface and blue-white on the inner. 

They require slightly different care from the European pines which tend to be hardier. They are perfectly hardy if they have been acclimatised to our growing conditions. If the temperature falls below -3°C protect in an unheated greenhouse. Place in full sun during the growing season. 

White pines do not like being kept too wet and do not like waterlogged soil. They do not need repotting very often. Once every three or four years is more than sufficient. Do not remove more than a quarter of the old root ball when repotting. 

In the Autumn, they shed a lot of the old (2 and 3 yr old needles) this is natural and nothing to worry about.
