How to identify Buffalo lawn weeds?

[zillah]

Hi All

I tried to use the below website to identify weeds that invade my Buffalo lawn

I figured out the name of the middle set of photos which is clover ,,,,hopefully I guessed right ?

But I couldn't figure out the name of the first set of photos and the last set pf photos

Hi @zillah,

Thank you for your question.

The first set of photos (Type A) is actually a seedhead from your buffalo grass. This is not a weed and should not be treated as such. Mowing is the only thing you should consider to control these.

The second set of photos (Type B) looks quite similar to clover, but I'm fairly certain it is actually creeping oxalis due to the yellow flower buds that are forming. You can use BuffaloPro Selective Bindii And Broadleaf Weed Killer Concentrate which kills both clover and creeping oxalis. Ensure you follow the manufacturer's mixing ratio and instructions for use and wear a mask, gloves and protective clothing when applying this herbicide.

Type C is a tough one. Is it growing in clumps or has it spread all across the grass? 

I often use Pl@ntNet identify for assistance with identifying plants before further research. This tool seems to think it could be celery that has gone to seed, and it looks very close to what you've photographed. I'm not so sure, but it is certainly a possibility.

Allow me to tag @Noelle and @mich1972 to see what they think it could be.

While we wait for their response if you dig around the base of this plant, does this reveal anything?

Let me know how you go.

Hi @zillah 

The markings on the leaves in the Type B photos lead me to believe it is a clover, rather than creeping oxalis, which is quite tiny and usually has a very small leaf and flower. The compound flower heads are more clover-like than oxalis.

Type C almost looks like coriander seed heads do you have coriander growing in the garden that has gone to seed?  If so, the seedlings have been kept low by mowing and it's only the flower/seed heads that have had the chance to grow above the lawn height.

When I dug Type C I have got this type of root

Yes I do have coriander at the back yard and as you know coriander has distinctive smell those one don't have any smell

Hi @zillah,

I'm stumped with that one. My thoughts were celery, coriander, dill or carroway. If it were celery I would expect a root mass larger than this, if it were the others I would expect an obvious smell.

I'll wait and see what @Noelle thinks.

Hi again @zillah 

It's the leaves of coriander that generally have the aroma and from what can be seen of the plants you have dug up, there are no true leaves on them. Possibly mowing has put an end to proper leaf development. The roots look very coriander-like to me.

No matter what the plants are in Type B and Type C photos, Jacob's recommended course of treatment should see an end to them, but you might need to repeat the spray 6-8 weeks after the first application to control the clovery weed in particular as it will have strong underground stems that will try to re-shoot after the original leaves look to have died off.
