This weed is growing out of control on the property since the dead trees were removed. I didn't see any until this year and it's everywhere along with the poke salat. Help? Thank you!

Compare to this: Horseweed (Conyza canadensis)

Whatever it is, it's about to bloom, then very soon after it will form, then drop many seeds for new plants to grow next year. Mowing or pulling very soon would prevent that from happening.

Looks like the stuff that grows all over in my area. Really easy to pull out, but boy there is a LOT of it!

Yes, there is tons of it and nodding it's not hard to pull out of the ground. The problem is that I have approximately 4 Acres of it. So pulling it is something I can't find the time to do unfortunately. The good news is that I have plans to run a tractor over most of it for vegetable farming next year. Thank You!

Mowing before new seeds are dropped this year would help reduce their numbers next year. Starting to bloom in your last pic.

Terri,

That is dog fennel. Dog Fennel (Eupatorium capillifolium) If in doubt, run your hands along the stalk growth. If they come away sticky, you can be assured, this is what it is.

As you mentioned, it is easy to pull them out as they are not very deeply rooted. I let some grow in my garden area just to provide some shade from the heat for other plants. But when I do pull them out, they don't come back terribly. It's easier to keep away than goldenrod for sure.

I agree with Tiffany, looks like Conyza canadensis.



This page has pics at various growth stages and says it has a smell reminiscent of carrots when parts are crushed:

Conyza Is an indicator of dry soil...
http://survlivel.cultu.be/indicator-plants

But then you probably knew that it was dry...
Up in Rome, the gardening should actually be a lot better than where I am...

I had areas that came up in thick patches of Conyza when I first turned the soil in my current garden... And after cleaning out the Conyza, I found that nothing else would grow... Except blackberry briars... And saw briars...

Yes, I think it is "Horseweed"....it's definitely not dog fennel - I am very familiar with that and also have tons of it too. Yes, the ground is very dry. I live in an unincorporated area referred to locally as "Flint Hill" if that tells you anything! The property was covered in about 35% hardwoods and 65% pine trees and most of them were dying naturally or were diseased. I had the trees removed so that I could garden more and reconfigure things over the years. So, this is the first year a lot of the property has seen sunlight. I have lots of other obnoxious weeds (loads of briars, poke salat, sumac, etc) as well as datura, virginia creeper, mullein ... But as I mentioned in my other post, the one weed I want and have none of is the milkweed Grumbling I should have made it clearer that I was searching for the blossoms, not the seeds - thanks for your replies on that post as well. I have so much to learn. I like the URL you shared on indicator plants, very interesting! Thank You!

Happy to suggest material for your investigation. ;) Good luck getting your property like-you-like-it! As an opinion, I'd concentrate my initial battles against non-native plants.

You had the trees removed?
At my house.... I take them down as needed for grilling and winter heat... Once they're all gone, I would have to bring in firewood... Ima take my time clearing...

I don't consider pokeweed bad, the birds eat the berries.

Sumac... I eat the berries... as well do the birds, even some caterpillars will defoliate sumac!

datura is pretty... I had the wild datura stramonium at my previous garden... I brought it... Haven't found any stands to collect seed from since arriving at the new garden...

Mullien is valuable... I brought that in too... Cowboy tp... And then there's the herbal applications.

AS much as I complain about the blackberry briars... I certainly appreciate the berries during those years when we get enough rain for them to plump...

And the smilax? also edible.

Also...

I don't know what you did with the trees that you had taken down, but another valuable use for them might be some hugelkulture beds.

Personally, I'm interested in giving it a try, but haven't yet... Gotta be some way to get the sand to hold moisture... And my attempt at lowered beds was a dismal failure.

Anyway, the idea is that you pile the trees up in a ditch or ravine, and then cover with soil... Instant garden bed.
