Urban Arborists

Bill Logan founded Urban Arborists to care for trees and shrubs where they matter most: in cities and suburbs, where they are often people's chief link to the natural world. Throughout the tri-state area, from backyard gardens in Bed-Stuy, to Manhattan townhouses, to cathedral and museum grounds, to New York City streets, to Westchester homes and estates, Urban Arborists brings the highest standards of knowledge, attention and care to the woody plants that transform lots into landscapes, yards into gardens, streets into groves.

You can now take a tree canopy walk four stories high and slide into a person-sized bird's nest at The Morris Arboretum. It's a great way to see trees the way birds (and arborists) see them..

To see great conifers, visit Bayard Cutting Arboretum in East Islip

Swarthmore College, near Philadelphia, has one of the best arboreta in the East. The trees and shrubs are beautiful, well-labeled, and appropriately used in garden settings. For a wonderful day trip, take Amtrak to Philadelphia and the regional SEPTA line right to the Arboretum at the Swarthmore stop. Look at their website, Scott Arboretum

If it's just too cold to admire trees outdoors, look at the lovely photographs by Larry Lederman in the Janet and Arthur Ross Gallery at The New York Botanical Garden.

Seasonal Activities

Autumn again. You’d think the fall would be a lousy time to plant trees, but it isn’t. For many species, it is the best time to plant. By this time, trees have formed their winter buds to protect next year’s embryonic growth. (The tiny leaves and stems, and sometimes even the next year’s buds, are already inside those tight-closed buds.) In September, too, the trees put finishing touches on their winter larders. If you slice a stem lengthwise and bathe it in iodine, you should see the cells around the buds turn dark grey or black. The color change marks the presence of starch that the plant has stored where it will be needed to fuel leaf-out next spring. So when you plant a tree in fall, you are planting something like a coiled spring. The whole plant is posed and ready for the coming year’s growth. Also, fall planting can give trees a head start in root growth. As long as the temperature remains above 40 degrees, tree roots can continue to grow, even after the leaves have fallen. A tree planted in autumn may already have taken hold of its new home, even before the first leaf sprouts in spring.
