Culture Notes

The Japanese Umbrella pine was chosen as a 1991 Gold Medal Plant by the Pennsylvania Horticultural Society for being a plant of exceptional merit, but underused in landscaping. Some shade in mid-day produces the best plants in the southern part of its range. The orange, peeling bark on older plants is quite attractive but is usually hidden by the foliage. Provide a moist, acidic soil and protection from the wind. Most trees in gardens are small due to the slow growth rate but there is one report of a tree more than 100 years old.
'Wintergreen' stays green even in the coldest of winters. 'Joe Kozey' has a narrow canopy.


Tree establishment specifications

Choose good quality trees for planting. The most common cause of young tree failure is planting too deep. In most instances, the point where the top-most root in the root ball originates from the trunk (referred to as the root flare zone or root collar) should be located just above the soil surface. You may have to dig into the root ball to find the root flare. If there is nursery soil over this area, scrape it off. Never place ANY soil over the root ball. The planting hole should be at least twice the width of the root ball, preferably wider because roots grow best in loose soil. In all but exceptional circumstances where the soil is very poor, extensive research clearly shows that there is no need to incorporate any amendments into the backfill soil. Simply use the loosened soil that came out of the planting hole. Simply planting with the topmost portion of the root ball slightly higher than the surrounding soil might still install the tree too deep - be sure to locate the root flare.
