| Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Dec 9, 2017 11:14 AM Northern Red Oak is one of the common climax forest trees, as it is the most tolerant oak in growing in shade when a young forest tree, in a large native range from southeast Canada & Nova Scotia down to southern Alabama to east Oklahoma up to northern Minnesota, widespread in many places. It is also one of the most common shade trees planted in landscapes in eastern North America and is offered by many nurseries. It grows about 1.5 to 2 feet/year and lives about 200 to 300 years. It is adaptable to many soils. It transplants easily as it does not develop a taproot. It bears one of the larger acorns for a member of the Black Oak subgroup that gets about 1.25 inches long that is loved by birds and mammals. It develops a good autumn color ranging from yellow to orange to red. It is a high quality plant that makes an excellent shade tree for landscapes. [ Reply to this comment | |
