Maidenhair Tree

[optinlocker]Maidenhair Tree is a beautiful, slow-growing tree that is tolerant of many urban extremes. In North America, this tree has been used in highly compacted sites, and in areas where air pollution is extreme. It has performed well in these areas without any visible deleterious effect.

In Victoria, Maidenhair Tree has been used extensively in park plantings, and also have been used occasionally as street trees in the City of Melbourne. These trees have proven their reputation of slow growth, and are maturing into relatively large, elegant trees. Seemingly, sites where water is freely available are better than dry sites for best growth. Some trees in Melbourne show signs of drought-induced die-back, but unless conditions are very harsh, Maidenhair Tree will survive and look lush.

The autumn foliage colour, leaf form and interesting habit make Maidenhair Tree a valuable street tree. When young (possibly for 15+ years) these trees are very upright, and with pruning, they can be maintained in a columnar form. Trees are of a single sex; the seed-producing trees are less appropriate for street trees as the fruit load can be quite heavy. Grafted pollen-producing trees are ideal for the landscape, and many of these trees also will maintain a fastigiate form for 50+ years.

G. biloba has slow root growth in containers and in the landscape. Because of this, typically 2 year trees are offered for sale; landscape managers should be aware of this root growth and plan for 2 years of establishment irrigation.[/optinlocker]
