Pinus koraiensis - 'Korean Pine'

Overall Description

Korean pine has a very unique growth habit, which lends itself very, very well for use as a bonsai subject. Also has good landscape value due to its hardiness - adapts to a wide variety of soil conditions, has excellent cold hardiness, and is well suited for urban conditions. We started growing / offering this selection due to numerous requests from our ever increasing number of bonsai enthusiast customers. This pine variety is well known for its edible, and highly distributed, pine nuts.

Korean Pine is native to more temperate parts of Asia ( mainly Korea, Manchuria, eastern Russia, and Japan ). It does best in loamy soils that drain well but, as previously mentioned, will adapt to a wide variety of :"less than ideal" soil conditions - just try to avoid soils or location that do not drain well. Excessive water / moisture around roots will cause a long term problem. Branching is dense with an overall pyramidal appearance when young, with branching becoming more open with age.

Uses include bonsai, screening & borders, as well as planted either singly or in small groups as an accent or specimen planting.

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
