With the arrival of warm temperatures, spring also brings insects that like to feed on your plants. Scale insects are common sap-feeders that attach themselves to stems and leaves and can weaken plants over time. You may notice small, immobile bumps (often tan, brown or gray), sticky “honeydew” on leaves and in some cases black sooty mold growing on that residue. Left unmanaged, heavy infestations can cause yellowing leaves, dieback, and reduced vigor. Get your trees and shrubs ready for a healthy growing season with care recommendations from your Bartlett arborist.

Spring is officially here but the changing temperatures makes it hard to believe. We have seen quite a bit of frost damage due to the over night freeze last week. Some of the affected trees in our area are Japanese Maples, Magnolias, Crape Myrtles, Chinese Chestnuts and Sycamores. You may notice browning and shriveling up of the leaves. Some leaves may even appear black in color. Not to worry though, if the tree is healthy, these leaves should drop off and within 4-6 weeks, you should start to see new growth. You can help the tree recover by watering it and consult with your Bartlett arborist about the best time to fertilize.

We proudly celebrate Robert Bartlett, Jr., our Chairman and CEO, for receiving the Elizabeth Medal of Honour, a distinction awarded by the Royal Horticultural Society to individuals who have made exceptional contributions to the advancement of horticulture. This recognition places Robert among a distinguished group of honorees shaping the future of our green world. Robert is the first American to receive the Elizabeth Medal of Honour, which was established in 2023 in perpetual remembrance of the late Queen Elizabeth II’s reign. In recognition of the duration of Queen Elizabeth’s reign, only 70 medals may be held at any one time.

The RHS states, “As CEO of Bartlett Tree Experts, Robert has overseen the expansion of operations across the United States and into Canada, the United Kingdom and Ireland, along with the development of a major research operation supporting the diagnosis of tree problems. He has created a vast arboretum that serves as research ground for the Bartlett Tree Research Laboratory and is managed to support learning, discovery, research, and training. The arboretum holds more than 26,000 accessioned plants from around the world and its staff are closely involved in conservation research in North American woodland ecosystems. Robert willingly shares the company’s knowledge, facilities, personnel, and assets for the benefit of arboriculture and those who work within it.”

Robert said, “It is truly an honour, made even more special with the opening of our UK research laboratory in the United Kingdom, which joins our Bartlett Tree Research Laboratories in the United States as a world-class research, diagnostic, and educational centre for Bartlett clients and arborists, and most of all, for the benefit of
preserving trees.”

Robert’s leadership of Bartlett Tree Experts and his dedication to scientific tree care, research innovation and global horticultural stewardship continue to elevate the entire industry.
Congratulations to Robert on this well-deserved honour!
