I grew up thinking every oak looked more or less the same. A big trunk, lobed leaves, and acorns everywhere in October. That assumption did not survive my first real walk through a mixed hardwood forest. Oaks are wildly diverse. Some drop their leaves each fall. Others stay green year-round. A few barely reach shrub…
I still remember the first time I stood under a weeping willow. The branches brushed my shoulders like curtains, and I wondered how many kinds of this tree actually existed. The answer surprised me. Quite a lot, actually. The genus Salix is one of the largest tree and shrub groups in the Northern Hemisphere. Botanists…
Ash trees (genus Fraxinus) are among the most widely planted shade trees in North America. That popularity is part of the problem. Monoculture planting makes entire neighborhoods vulnerable to a single pest or pathogen wiping out every ash on the block. The scale is staggering. Forest inventory data shows that forest lands in the lower…
I still remember the first time I saw a serviceberry in full bloom. It looked like a soft snowfall had landed on a single tree in early spring, weeks before anything else in the yard had even woken up. That moment is why I wanted to write this guide. Serviceberry, scientifically known as Amelanchier, is…
Pine trees feel permanent. They tower over yards, line highways, and anchor entire forests for decades without complaint. So it’s genuinely unsettling when one starts browning from the bottom up. I’ve spent time digging through university forest pathology reports, and one thing stands out clearly: pine diseases move faster and hit harder than most people…
Palm trees carry a certain promise. They mean warm weather, ocean breezes, and a landscape that feels a little more relaxed. So when one starts to decline, it hits differently than an ordinary tree problem. I’ve researched enough plant pathology reports to notice a hard truth: many of the deadliest palm diseases have no cure…
Dogwood trees are the quiet stars of spring. Their white and pink bracts light up yards, parks, and forest edges across the United States every April and May. But I’ve noticed something over the years of writing about landscape trees: dogwoods get sick more often than most homeowners realize. Some of these diseases are cosmetic…
Japanese maple, botanically known as Acer palmatum, is prized for its delicate foliage and dramatic color. That same delicate nature, unfortunately, also makes it more vulnerable to disease than many other landscape trees. I have lost count of how many worried messages I have seen in gardening forums about a Japanese maple suddenly wilting on…
Red maple is one of the most common trees in North America, and university sources describe it as one of the most abundant native trees on the continent. Popularity, though, comes with a long list of well-documented problems. I planted a red maple in my own yard years ago, mostly for the fall color everyone…
The Fall Fiesta maple is a patented cultivar of the sugar maple, scientifically named Acer saccharum ‘Bailsta’, and sold under the trademark Fall Fiesta®. It carries U.S. Plant Patent PP 11119, developed and introduced by Bailey Nurseries. It is not a hybrid of red and silver maple, despite what some retail listings imply. Purdue University’s…
