Fall Leaf Season in Columbus: Keeping Gutters Clear

By Columbus Gutter Repair & Replacement · September 11, 2026 · 5 min read

Mid-September, and the buckeyes on the Ohio State campus and along the Olentangy are already dropping nuts and yellowing. That's the start of a leaf season in Columbus that runs almost three months, from the first buckeyes to the last pin oak leaf in early December. Clean the gutters at the wrong point in it and you'll be doing it again.

The calendar, by tree

Ohio buckeye and horse chestnut — mid-September into October. First to turn, first to drop. Big leaflets and the nuts, which fit a 2x3 downspout perfectly and plug it.

Black walnut — late September. Leaflets fall early and the nuts follow. Walnut hulls stain everything they touch and mat into a paste in a gutter.

Honey locust and Bradford pear — October. Tiny leaflets from the locust that get through any screen, and the pear holds its leaves late then drops them all at once in November after a hard frost.

Silver maple, sugar maple, red maple — mid-October to early November. The main event in Clintonville, Beechwold, Worthington and Upper Arlington. Silver maples are the most common big tree in the older neighborhoods, and they drop by the ton. This is the drop most people clean after, and the mistake is thinking it's the last one.

Sycamore — late October into November. Huge leaves that curl and stack; bark flakes all year; seed balls that hang on and break up in spring.

Pin oak, red oak, white oak — late November into December. Oaks hold their leaves longest, and pin oaks — the street tree of choice in 1950s–60s Columbus suburbs — keep some brown leaves through the winter and drop them onto a frozen gutter in January. If you have oaks, an October cleaning is a cleaning you'll pay for twice.

Cottonwood and willow — spring, not fall. Cottonwood fluff in June is what mats on top of guards. Worth knowing for the May cleaning.

When to clean

If your trees are maples: early to mid-November, after the drop finishes.

If your trees are oaks, or a mix: late November to early December. Watch the pin oaks; when they're mostly brown and thinning, go.

If you have both and can only do it once: early December. A few maple leaves sitting for three weeks does less harm than a gutter full of oak leaves going into January frozen.

The reason timing matters here and not in, say, Atlanta is what comes after. A gutter that goes into winter full of wet leaves holds water, freezes into a block, and either pulls the hangers out under the weight or backs melt water up behind the gutter onto the fascia during an ice dam. A good share of the re-hangs we do every March started with a fall cleaning that didn't happen or happened in October. Gutter cleaning runs $120–$300 by house size.

What to actually do

1. Scoop by hand into a bucket, not a leaf blower into the neighbor's yard. Wet maple leaves don't blow.
2. Flush every downspout from the top with a hose and watch for a full stream at the bottom. Buckeyes, walnuts and a pin oak leaf plug in the elbow are what stop it.
3. Check the corners while you're there. A drip stain under a corner now is a split corner in February.
4. Put the extensions back. The mower moved them.
5. Stop if the ladder is on the gutter, if you're on frost, or if the eave is two stories up.

Do guards fix this?

Partly, and it depends on the tree.

A guard changes a fall cleaning from a scoop-out to a hose-off from the ground, and cuts it from twice a year to once. Under old maples and oaks that pays for itself in six to eight years. Under two young ornamentals in a 2010 subdivision it doesn't, and the guards page says so.

Winter is the reason

None of this is about leaves in the gutter being unsightly. It's about what a full gutter does between December and March. Clean before the freeze, and the gutters come through winter straight. Don't, and you're calling in March about a run that's hanging by two spikes. The winter checklist picks up where this one leaves off.
