Although mayhaw is tolerant of wet, very acid soils, better growth is achieved when it is planted on well drained, slightly acid soils. Mayhaw trees are long-lived and may have a 30 feet canopy diameter after 20 years. Because of the growth potential, recommended tree spacing for a permanent orchard is 15 to 20 feet in the row and 18 to 20 feet between rows (giving 109 to 161 trees per acre).
