Tree Trimming & Pruning in Frankfort, IL

Pruning Guide for Frankfort Trees

In Cool-Humid climate (Zone 6a), timing matters. Pruning at the wrong time can stress trees, invite disease, or kill them outright.

Frankfort Pruning Calendar

Late winter (February-March). Oaks: November-March ONLY (oak wilt restriction)

What Type of Pruning Do Your Trees Need?

• Crown cleaning - removing dead, diseased, and crossing branches. The most common and important service. Every Frankfort tree benefits from this every 2-3 years.
• Crown thinning - selectively removing interior branches to reduce wind resistance and improve light penetration. Important for dense canopy species like Bur Oak.
• Crown raising - removing lower branches for clearance over sidewalks, driveways, and structures. Especially needed for ~27-year-old trees that have grown into walkways.
• Crown reduction - reducing overall canopy size. Only appropriate when trees have outgrown their space. Never "top" a tree - proper reduction cuts back to lateral branches.

Bur Oak

Toughest native oak - drought, cold, and wind tolerant. Massive specimens

Sugar Maple

Fall color champion, syrup production, but salt-sensitive along roads

White Birch (Paper Birch)

Iconic white bark, short-lived (40-50 years), bronze birch borer vulnerable

Freeze Protection for Frankfort Trees

With January lows averaging 16.1°F in Frankfort, freezing temperatures can damage non-native and marginally hardy species. Tropical and semi-tropical plantings are particularly vulnerable.

Active Tree Threats in Will County

Emerald Ash Borer (EAB) critical

Affects: All ash species (Fraxinus) - green, white, black, blue ash

Metallic green beetle native to Asia. Larvae feed under bark, cutting off water and nutrient transport. Tree dies within 2-5 years of infestation. Has killed hundreds of millions of ash trees in North America since 2002.

What to do: Remove dead standing ash trees immediately - they become brittle hazards within 1-2 years. Preventive trunk injection (emamectin benzoate) can save high-value ash but requires biannual treatment.

Spotted Lanternfly high

Affects: Tree of Heaven (primary host), but feeds on 70+ species including maples, oaks, walnut, willow, birch, grape

Showy planthopper from Asia. Feeds on sap, excretes honeydew that promotes sooty mold. Doesn't usually kill trees directly but weakens them and creates a mess. Major agricultural pest on grapes and orchards.

What to do: Destroy egg masses (gray mud-like patches on any flat surface) October-June. Remove Tree of Heaven from property to eliminate breeding host. Report sightings to state agriculture department.

Oak Wilt high

Affects: Red oak group (red, pin, scarlet, black - usually fatal). White oak group (white, bur, swamp white - slower, sometimes survivable).

Fungal disease (Ceratocystis fagacearum) that clogs water-conducting vessels. Red oaks can die within weeks. Spreads through connected root systems between nearby oaks and via beetles attracted to fresh wounds.

What to do: NEVER prune oaks between April and October - beetles carry the fungus to fresh cuts. If an oak shows sudden wilting/browning, get a certified arborist assessment immediately. Root barriers can prevent spread between adjacent trees.

What 1980s-2000s-Era Trees Need in 2026

Common Issues

• **'Crepe Murder'** - the epidemic of bad pruning (topping crepe myrtles into ugly stubs) has created structurally compromised trees with weak regrowth across the South.
• **Approaching first major maintenance** - trees in this age range are large enough to need professional pruning for the first time. Many homeowners haven't budgeted for it.
• **Raywood Ash decline** - widely planted in California in the 1990s, now showing anthracnose and structural decline

Recommended Actions

• Structural pruning NOW - this is the critical window to establish good branch architecture before trees get too large
• Stop 'crepe murder' - educate on proper crepe myrtle pruning (remove crossing/rubbing branches, not indiscriminate topping)
• Replace short-lived ornamentals (purple-leaf plum, Bradford pear) that are declining
