Terminal Bud Scar: A Tree's Health Chart
Scarred for LifePaul Hetzler, ISA Certified ArboristIt makes sense that dying trees have terminal bud scars. Sounds like an awful condition – my condolences. But the healthiest trees have them, too (terminal scars, not condolences). It’s a good thing, since terminal bud (aka bud-scale) scars provide an excellent way to leaf through a tree’s health records going back 5 to 10 years.After a woody plant has its full complement of leaves, and they have hardened off, that tree or shrub makes both…See More
Treeconomics 101: Early Fall Color Explained

New Beech Threat Nothing to Sneeze At

Forest Pests are Exploding
Forest Health ForecastIf you’re tired of hearing about new invasive forest pests, I’m right there with you. Seems they arrive at an ever-increasing pace, and the harm potential ratchets up with each newcomer. At this rate maybe we’ll get a wood-boring beetle whose larvae explode, which would put things in perspective. As distasteful as it is to peer at the cast of ugly new characters, it’s better to know what we’re up against.Novel pests put everyone on a steep learning curve. For the species…See More
Preventing Anthracnose and Apple Scab
Crabby Apples and Other ComplaintsWe waited a long time for summer to arrive this year, so it is unfair that some flowering crabapples are turning yellow and brown and shedding their leaves already. Mountain-ash, serviceberry, and hawthorn are also affected by the same disorder. Here and there a few maples and other species are also dropping random leaves, which are for the most part still green, often with patches of black or brown. The latter situation has a different origin, but both are…See More
Oak Wilt: You Can Make a Difference
Oak WiltIt’s hard to be cheerful in a job where I am expected to keep up on each newly arrived or imminent threat from invasive insects, novel plant diseases, and worrisome trends in the environment. Although I typically deflate everyone’s happy-bubble when I give a talk, I’ve discovered we need not fret that the sky is going to fall.The National Atmospheric Deposition Program (NADP) is a joint effort of research institutions, government agencies and nonprofit groups; their mission is to…See More
Healthy Forests, Healthy Fish
Fish ForestryAs many anglers know, trees and fish are closely related. Really; it goes way beyond basswood. The relationship is not in the sense of phylum or family, of course. And it's not like the way in which tomatoes and fish were briefly married in a 1996 experiment at Oakland, California-based DNA Plant Technology in an attempt to get a frost-tolerant tomato (or possibly a saucy fish). If it weren’t for tree cover, cold-water fish species would not survive in most of the streams they now…See More
Trees Are Sick of the Weather
Maple Motion SicknessNo one wants to be told they have a weathered complexion, but many trees this summer, especially maples, are looking a bit worse for the wear as a result of conditions earlier in the season. “Leaf tatter” is a term used to describe foliage which may be torn and bedraggled-looking, distorted, sometimes with blackened spots or zones. It can easily look like a disease or mysterious pest is ravaging the tree.As tree buds open and young leaves begin to unfurl, they can get…See More
Ice Meadows
(N)ice MeadowsNow that the weather has finally warmed up, we can appreciate ice a little more. Among other things, ice greatly improves summertime drinks, and an icy watermelon is hands-down better than a warm one. And in this part of the world, ice also provides us with unique wildflower meadows. Along stretches of riverbank in the southern Adirondacks, rare Arctic-type flowers are blooming now in the fragile slices of native grasslands that are meticulously groomed each year by the scouring…See More
Perennial Pet Peeves
Local VolcanoesWhen you think about it, landscape trees have a rough life. Firstly they don’t get to choose their neighborhood, whether good, bad or indifferent. Depending where they are planted, they may need to contend with helpful watering by territorial dogs, materials-testing by energetic kids, entanglements with errant kites, or other issues.Rooted in one spot day in and day out, year after year, they suffer from – well, boredom, I imagine. And from restricted root area, drought stress,…See More
Helping Trees Recover from Flooding
Most Things in ModerationAs a teenager, my son had a saying, whether original or borrowed I don’t know (the saying, that is), which went something like “All things in moderation. Especially moderation.” It would seem Mother Nature took that to heart, and dispensed with moderate rainfall and snow melt this spring. If not her, then maybe it was Creepy Uncle Climate Change. At any rate, the resultant flooding has been heartbreaking to observe.While I am of course sensitive to the anguish of those…See More
Happy Tree Day!
Plant a Legacy on Arbor DayMuskrat Week. Velcro Month. Arbor Day. You know it’s an obscure event when the greeting-card trade hasn’t bothered to capitalize on it. While not the best-known observance, Arbor Day has a respectable history, as well as a local connection.Rooted in northern NY, Arbor Day is observed on the last Friday in April. J. Sterling Morton of Adams, NY germinated the concept in 1872 to highlight the need to conserve topsoil and increase timber in his adopted state of Nebraska.…See More
