Still, S.M. | Gilliam, C.H. | Watson, M.E.
The response of container grown Acer rubrum 'Red Sunset' to three nitrogen levels applied from June to September was studies. Trees fertilized at 150 and 300 ppm N exhibited a second growth flush. Tissue analysis of mature and immature leaves indicated that trees fertilized with 300 ppm N contained higher N concentrations. Fall color of plants fertilized with 50 ppm N was fully developed 3 weeks before plants that received 300 ppm N. Subsequent growth the following spring was significantly greater on trees fertilized with 300 ppm N.
