What Tree & Shrub Seedlings looks like
Baby trees and shrubs sprouting where nobody mows — boxelder and maple, wild cherry and chokecherry, Kentucky coffeetree, autumn olive, forsythia — usually in a telltale line along a fence, under a wire, or against the foundation where a bird sat. The giveaway is the stem: stiff, round and already turning woody at the base, with true leaves that look like a miniature tree leaf rather than a weed.

Best approach: Spray or dig
Big-seeded trees are the exception — acorns and similar carry enough stored energy to keep regrowing through repeated mowing, so dig those out. Autumn olive gets no grace period either: it is invasive, fruits within three years and resprouts hard when cut, so treat the stump or dig it rather than just lopping it.

When to treat Tree & Shrub Seedlings
Cut and treat the stump from late summer through autumn, while the plant is moving reserves down to its roots — spring treatments fail because the sap is flowing the other way.
Chemical treatment
Most seedlings in a lawn need no herbicide at all, because the mower already handles them — chemicals are for the one that got past you, went woody, and now resprouts every time you cut it. Use the cut-stump method: cut the stem close to the soil, brush off the sawdust, and within minutes paint the cut face with a concentrated triclopyr brush killer (above 8% active ingredient, undiluted) or concentrated glyphosate at about 20%, using a dauber rather than a sprayer. Late summer through autumn is the right window, when woody plants move reserves down to their roots; spring applications fail against the upward sap flow. A bottle labelled brush killer is not a lawn product: glyphosate is non-selective and kills any grass it lands on, and triclopyr, while tolerated by tall fescue, Kentucky bluegrass, ryegrass and fine fescue, must never be broadcast over bermuda, zoysia, St. Augustine or centipede. Keep both on the stump and off the turf and your grass type stops mattering.
Non-chemical management
Mowing wins, and for most lawns it is the entire treatment — keep mowing at your normal height and seedlings never make it out of the turf. Do not scalp the lawn to hurry it along. Elsewhere, hand-pull when the soil is soaked: grip low and pull straight up so the root comes too, because a sideways yank snaps the stem and it regrows from the crown.
How to stop Tree & Shrub Seedlings coming back
The pattern maps where seed lands and nothing mows: fence bottoms, behind the shed, the mulch line, under bird perches. Trim those strips on the same schedule as the lawn, keep beds mulched two to three inches deep, and the problem mostly disappears.
