RT Journal Article SR Electronic T1 Effect Of Tree Wrap On The Incidence Of Frost Crack In Norway Maple JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 226 OP 227 DO 10.48044/jauf.1978.056 VO 4 IS 10 A1 John H. Hart A1 Gurdon K. Dennis YR 1978 UL http://auf.isa-arbor.com/content/4/10/226.abstract AB During the winters of 1970-1971 and 1971-1972, frost cracks developed on Norway maple cv. ‘Emerald Queen’ planted in a Michigan nursery. Trees in low areas or on poorly drained soils were more frequently injured than those planted on better drained soils. Wrapping trees in November, 1971, with bands of Kraft paper did not reduce the incidence of frost cracks during the 1971-1972 winter.
