|Diseases & Insects:
||Probably the most trouble free birch but, in moist years, significant leaf spot is common that causes premature defoliation of older leaves.|
||Very handsome specimen tree for estates, parks, golf courses, campuses and other large ares; particularly well suited to areas which are wet a portion of the year yet may be quite dry in the summer and fall; handsome for bark character and should receive wider landscape use as it becomes better known; River Birch is being planted more widely in the south|
||Best adapted to moist soils and is usually found in the wild along stream banks and in swampy bottomlands which are periodically flooded; will survive in drier soiols although reaches its maximum development in moist, fertile areas; prefers an acidic soil (6.5 or below).|
||Don't prune this birch and other birches until summer as they are "bleeders" and should not be cut when sap is flowing..|
||Fertilization is beneficial only when nutrients are lacking. A soil test should provide you with the nutrient levels with in the ground.
||Dig a hole three times the diameter of the root system, with a depth no deeper than the original soil line on stem. 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.
