||Deciduous Ornamental & Shade Tree|
||Leaves are alternate, simple, in clusters of 3 to 5 on spurs or alternate on long shoots, fan shaped, dichotomously veined, more or less incised or divided at the broad summit, 2 to 3 inches long, 2 to 3 inches wide and bright green during the spring and summer. Leaves turn a wonderful butter yellow in the fall and all drop within a 48 hour time window.|
||50 to 80 feet in height with a tremendously variable spread ranging from 30 to 40 feet depending on the cultivar.|
||Zone 3 to 8. For an idea of your plant zone please visit the USDA Plant Hardiness Zone Map.|
||Usually pyramidal in outline when young; in old age often becoming wide spreading with large, massive, picturesque branches; it is quite difficult to adequately describe the habit of this tree due to the tremendous variation in plants grown from seed; the male tree is supposedly more upright than the pistillate form.|
||Slow to medium.|
||Dioecious, male flowers (green) are borne on the short shoots in cylindrical, 1 inch catkins during March-April; the female on a 2 inch long pedicel bearing 1 or 2 greenish ovules. Female flowers eventually produce troublesome seeds which are coated with butyric acid that smells of rancid eggs or vomit.|
|Diseases & Insects:
||Extremely free of pests. It's almost as if this tree has outlived any diseases or insect problems from the distant past.|
||Excellent city tree, public areas, perhaps too large for street use buit is used extensively for this purpose; a well developed Ginkgo is an impressive sight; often looks out of place in the small residential landscape because of unique foliage and winter habit; tends to be somewhat gaunt and open in youth but with time becomes one of the most spectacular of all trees; fall color alone is sufficient reason to plant this tree.|
||Prefers sandy, deep, moderately moist soil but grows in almost any situation; very pH adaptable; displays good soil salt tolerance.|
||Water regularly after initial planting and prune in spring as necessary to maintain form and desired shape.|
||Fertilize an area three times the canopy spread of the tree 1 to 2 times a year with a 10-10-10 fertilizer. Only fertilize an established tree.
||Dig a hole three times the diameter of the root system, with a depth no deeper than the original soil line on trunk. Break up the soil to the finest consistency possible. Place plant in hole and fill, compacting the fill dirt. Water the plant heavily to seal soil around the roots and remove air pockets. Water well, and remember to water regularly until they have started to grow.
