The addition of larger amounts of nitrogen to the soil will give great results and will diminish the splitting issues with maples attributable to verticillium wilt.

This is the most commonly sold cultivar of the hybrid species between the Red x Silver Maples. I have worked at nurseries where it was sold in both Illinois and Pennsylvania. In the Chicago area, the good quality prairie soils usually have surface pH of 6.8 to 7.1, even higher, and so the Red Maple, commonly planted as a good shade tree, maybe about 1/4th to 1/3rd of the instances develops magnesium deficiency leading to yellowed foliage because it must have a pH not above 7. Because Silver Maple is good to about pH 7.5 or so, the hybrid tree does not develop chlorosis as easily in the area. The hybrid also grows faster than the Red Maple. (The Silver maple is not a recommended shade tree because it is softer wooded and subject to breakage and often grows too big. It does not get a really good fall colour either. I have seen a few Silver Maples get terrible yellow chlorosis of foliage in the Chicago area where the soil reaction was definitely alkaline.)
