WEED ID · ANNUAL OR PERENNIAL BROADLEAF

Slender aster

Also called Annual saltmarsh aster, lawn American-aster, southern annual saltmarsh aster

A wiry, branching broadleaf with lots of tiny daisy-like flowers. It gets woody and harder to control as the season goes on.

When you’ll see it: Blooms late summer into fall

How to spot it

Thin, wiry stems that turn woody as the plant ages
Narrow, linear leaves, one at a time along the stem
Many small daisy-like flowers with yellow centers
Petals pale lavender, blue, pink, or white
Can stand taller than the turf, sometimes several feet

Why it shows up

Slender aster spreads readily and can take hold in lawns and disturbed ground. It makes many small flowers late in the season. The older and woodier it gets, the harder it is to get rid of.

How we treat it

Slender aster is easiest to deal with while it is young, before the stems turn woody. We spot treat with a product labeled for your grass type and come back if new plants show up. We also fertilize to keep your turf thick.

What you can do

Catch it early. Older plants get woody and tough.
Mow on a regular schedule.
Call us if you see it spreading, and we will take a look.
