Hi, I have this yellow flower, not marsh marigold, but the invasive lesser celandine. I don't know how it came about in my yard, but it is hard to get rid of each year, digging and spraying and it migrating into neighbor's yards. What can I do? I have used glyphosate Round-Up. Can I be held accountable and sued for this unruly plant? Thank you, Kathy Argo

Last summer my lawn was sprayed with Roundup in preparation for a new lawn installation. For 2 1/2 months prior to the installation, if anything green appeared it got hit with Roundup. After my new lawn started growing, unsightly grasses started appearing everywhere and I do mean everywhere, totally ruining the appearance of my new lawn. The seed used was Lesco's All Pro Team Mates Plus. My gut feeling is that this unsightly grass or weed probably was in the topsoil that was brought in. Can anyone identify it so I know how to kill it. It did not die off in the fall. The attached photos were taken 3/27/23. I live in NWOhio where the soil temperature has been below 50 degrees. I have my lawn sprayed each summer professionally with Tenacity and I am hoping it will kill whatever this might be.

I am looking for an herbicide or combination herbicides that will not harm violets or clovers. My research so far has found clethodim to be effective and killing grass and butrac can kill broadleaf weeds without harming clover. Could not find information about this priduct on violets. Also it carries Danger label which i try to avoid, Which hercide(s) could you recommend that will not harm clover or violet, but will eliminate most other plants? thank you Chris

A patron called and would like to know what kind of weed/grass killer he can use that would be safe for use around his Douglas Fir trees. Please advise. Thank you.

Please see the attached pictures, wild grass has overgrown on my flower garden which also includes four rose plants. I'm not physically able to pull this mess out as it was suggested. Is there a solution to getting rid of this grass without killing my plants and rose bushes. I appreciate your help with is matter.

Found near Potomac River in woodland setting. It looks like a type of toothwort??? Thx

We have a very large Pin Oak beside our home that we adore but are concerned about it's overall health. We've only lived in the house for 3 years and the tree lost it's leader sometime in the past, and appears to have suffered from poor pruning and storm water management. We trimmed all the deadwood out winter 2021. Are arborists available to provide health assessments that aren't also looking to get hired? Most all arborists we've talked to push cutting the tree down. Even if that is the correct path forward we'd feel a lot better hearing it from a few unbiased arborists. Thanks! Gary

Hello, I have a question about some tulip and narcissus bulbs I'd like to ask an OSU master gardener but do not know how I can contact them? Thank you

Hello, I have the dreaded invasive Italian Arum. I've tried to dig it out over the last couple years - disposing of rootlets, bulbs, and surrounding soil - but despite my efforts it's coming back year after year and continuing to spread. I never use chemicals to control weeds but the extreme invasiveness of the arum is making me consider an exception to this rule... I would love to hear any strategies you have to eradicate this plant. Boiling water, blowtorch, less toxic/highly targeted herbicide...? Thanks in advance for any ideas!

Greetings! I have six daphne, three of them are experiencing an odd blossom issue on a few branches. I'd describe the affected blossoms as cauliflower-like. The end of the twigs with the odd blossoms are 'flattened'. Thanks for your help!
