2/26/2024 0 Comments Maple tree types of nhFall color is highly variable, and can be affected by the timing / amount of fall rains, temperatures and frost. A dry early summer could easily explain the smaller than usual leaves. You didn't mention your weather / water situation this year. Presumably would require some percentage of the mass of the tree. Fertilizer is not going to be practical on trees this large. Breaks up hard layers, lets me check for big rocks, soil quality. When I plant trees (and shrubs, blueberries, etc) I dig deep, maybe a hole 3' wide and 2-3' deep for a tree. Is soil good for more than just the top few inches? Sometimes when houses are built yards are shaped with horrible soil and a thin layer of topsoil is spread on top to grow grass. Any farmer's co-op and most farm stores have the sample kits and can tell you where to send them. Might be best to get a soil sample first. There are foresters around here who will come out and check trees and give advice for little or nothing. Sure the easy answer is climate change but these trees do well in Ohio and Virginia and many other places.Īnd I'm not buying 'the pandemic' either.ĭid you fertilize? Can help a lot but too much is bad.īest to call a local arborist or perhaps a forester. This year they just turned yellow/brown and fell. These did that at first but have gradually developed smaller leaves that have less color. Usually /Sugar Maples grow leaves as big as your hand which turn brilliant red and orange in the fall. They have always been vigorous and healthy. dissertation.30 years ago we planted 3 Sugar Maples in the yard. Assessing the potential of invasiveness in woody plants introduced in North America.

Ecological Threat Acer platanoides is able to shade out native understory vegetation such as spring ephemerals, and eventually out-competes native tree species in the forest canopy. The samara wings are divergent, reaching nearly 180 degree angle to each other and are dispersed by wind. The fruit are samaras that are green when young and turn yellow, then brown, with age. Fruit The pendulous fruit measure 1.5-2 in. They are borne in erect, pedunculate, rounded corymbs. Flowers The flowers appear in April and May and are yellow-green in color. The fall color of the green leaves is yellow. The leaves are usually green in color, but there are some cultivars that have dark red leaves. The leaf petioles exude a white sap when broken. Foliage The palmately lobed leaves are opposite and have 5 to 7 sharply acuminate lobes (with large but few teeth). The bark of the tree is grayish and regularly and shallowly grooved. (12-18 m) in height, but can reach heights of 100 ft. Appearance Acer platanoides is a tree that usually grows to 40-60 ft.
