Providing the Highest Standard of Care for Your Trees and Shrubs.
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 you are up for some exploration, try to find the amazing white oak in Pelham Bay Park in the Bronx. It is in the northeast corner of the park, but off the main trails. If it were in England, they would be making pilgrimages to it. Two years ago, Urban Arborists placed a faux-bark shield on a large hollow to keep people from setting it afire.

This year spring warmed early, and then the cold came back. The shock of the cold caused damage to some plants; and believe it or not we are also seeing the continued effects of the bitter cold winters of 2013-2014 and 2014-2015. We were lucky to have an extended spring planting season, but now we are solidly in summer.
Summer is a good time to prune trees, unless the weather becomes extremely hot and dry. It is important for our clients to be on the lookout for thirst in plants, as this is a much more common cause of plant health problems than pests tend to be. Be on the lookout for branches that could be damaged during storms – pruning can go a long way towards preventing storm damage, particularly on large trees. Our pruners aim to maximize stability in tree crowns while preserving trees’ beauty and function.
That said, fall webworm should begin appearing any moment now. Though we have not been seeing as much powdery mildew, we have been seeing a good deal of aphid infestations, as well as scale insects.
European fruit lecanium, a scale to which our entomologist friend Dan Gilrein attributes “tremendous biotic potential”, is out in full force. This scale forms a thick crust with its brown, almost shiny exoskeleton, and a thinner, whitish-greyish crust around and underneath. Many purpleleaf plum trees (Prunus cerasifera) eventually become infested with it.
