Common Trees in Allen County and How to Care for Them

By the Fort Wayne Tree Pros team · May 23, 2026

If you’ve owned a house in Fort Wayne for more than a year, you’ve probably wondered what the big tree in your backyard actually is — and what it needs from you. Allen County’s mix of mature neighborhoods, post-war developments, and newer subdivisions means there’s a fairly predictable set of species you’ll find on most properties.

Here’s a field guide to the most common trees in our area and how to care for each.

Silver Maple (Acer saccharinum)

Probably the single most common large tree in older Fort Wayne neighborhoods. Silver maples grow fast (which is why they were planted everywhere in the 1950s and ‘60s), but they have brittle wood and shallow roots that lift sidewalks and clog drains.

Care: Have a qualified crew thin and reduce heavy, overextended limbs every 5–7 years. Watch for cracks at major branch unions. Keep them away from septic and sewer lines.

Red & Sugar Maple

Common newer-development trees. Much better structure than silver maple, with brilliant fall color (red maple in October, sugar maple slightly later). Generally low-maintenance.

Care: Light structural pruning in late winter or mid-summer (they bleed sap heavily in March, which is cosmetic but startling). Watch for verticillium wilt.

Pin Oak (Quercus palustris)

You’ll spot pin oaks by their pyramidal shape and the lower branches that swoop down toward the ground. Very common in mid-century Fort Wayne yards. They hold onto brown leaves through winter.

Care: Prune only in late winter (oak wilt risk April–July). Pin oaks often develop iron chlorosis (yellowing leaves with green veins) in alkaline Allen County soils — treatable with soil acidification or iron treatments.

Bur Oak & White Oak

The kings of the Indiana hardwood forest, and some of the strongest, longest-lived trees you can have on a property. You’ll find old white and bur oaks in lots near Foster Park, Lakeside, and parts of Aboite.

Care: Minimal pruning needed. Same April–July avoidance for oak wilt. Protect the root zone from construction and grade changes — oaks are very sensitive to root disturbance.

Sycamore (Platanus occidentalis)

Massive native tree with the unmistakable peeling, mottled bark. Common along the St. Marys and Maumee rivers and in some larger yards. They drop big leaves and seed balls.

Care: Sycamores host anthracnose, which causes a leaf scorch and twig dieback in cool wet springs. Usually cosmetic, not fatal. Rake fallen leaves to reduce fungal carryover.

Sweetgum (Liquidambar styraciflua)

Tall, beautifully shaped trees with star-shaped leaves — and the infamous spiky “gumballs” that destroy bare feet and lawnmower blades. Common in 1970s–‘90s Fort Wayne subdivisions.

Care: Generally healthy, low-maintenance. The gumballs are unavoidable on standard sweetgums (there are fruitless cultivars for new plantings).

Hackberry (Celtis occidentalis)

Underrated native tree that grows just about anywhere in Indiana. You’ll often see them as “volunteer” trees in fence rows and yard corners. Identifiable by warty bark and small dark berries that birds love.

Care: Hackberries get nipple gall on the leaves (cosmetic) and witch’s broom in the canopy (also mostly cosmetic). Prune for structure when young.

Tulip Poplar (Liriodendron tulipifera)

Indiana’s state tree. Tall, straight, with distinctive tulip-shaped leaves and orange-yellow flowers in May. Common in larger Fort Wayne yards and along the Three Rivers Greenway.

Care: Very tall and prone to limb drop in summer storms. Keep heavy limbs reduced near houses. Surprisingly fragile root system — protect during construction.

Ash (Fraxinus species) — Mostly Dead

Once one of the most common shade trees in Fort Wayne, ash has been devastated by emerald ash borer. If you have a standing ash that’s never been treated, it’s almost certainly dead or dying.

Care: Dead ash become extremely brittle — remove sooner rather than later. Living, treatable ash can be preserved with injections every 2–3 years by a certified applicator. See our article on emerald ash borer in Fort Wayne for more detail.

Honeylocust (Gleditsia triacanthos)

The thornless ‘Skyline’ and ‘Shademaster’ cultivars are common in parking lots, street plantings, and yards. Light, dappled shade. Generally tough.

Care: Watch for canker diseases on stressed trees. Tend to develop multiple leaders that need structural pruning when young.

Bradford Pear (Pyrus calleryana)

The pretty white-flowering trees that line so many Fort Wayne subdivisions — and that absolutely shred themselves in every ice storm. Now considered invasive in Indiana.

Care: Selective limb reduction can buy you time. Most reach the end of their useful life by 20–25 years and split apart in a storm. Many homeowners are choosing to remove them and replant with native species.

Eastern Redbud (Cercis canadensis)

Small native ornamental with the unmistakable purple-pink flowers along bare branches in April. Common understory and yard tree.

Care: Generally easy. Prune lightly after bloom to keep a good shape. Can be susceptible to canker on stressed trees.
