Two more great articles about crabgrass germination.

Just to share some great articles about crabgrass germination.

Dr. Patton and Dr. Street of Purdue and Ohio State posted 2 great reads that expand on my recent article about crabgrass. Dr. Patton’s article has some great research citations.

Buffalograss Greening up: Round-Up for weeds?

While standing over this plot, the buffalograss looks completely dormant.

Typically in Feb and March I get calls from people wanting to control weeds in their buffalograss lawns. And they have heard that they can spray Round-Up (glyphosate) on their lawn to control weeds. Yes this is true. You can spray Round-Up on dormant buffalograss. Since the buffalograss is ‘sleeping’ and not growing, it will . . . → Read More: Buffalograss Greening up: Round-Up for weeds?

Winter Weeds. I’ve seen a Bunch!

Henbit in flower bed

I don’t know if it was the exceptionally warm weather or the over-abundance of weak and damaged lawns from last summer/fall, but I’ve seen an exceptional amount of winter annual weeds like henbit and common chickweed, just to name 2 that I’ve seen.

I’m guessing that it is a combination of the two. The warm . . . → Read More: Winter Weeds. I’ve seen a Bunch!

Crabgrass or Knotweed germinating, don’t panic!

I posted some pictures on Twitter over the weekend of some Knotweed germinating.

Don’t forget knotweed germinates before crabgrass. So if you see germinating seedlings probably knotweed. Like this. twitter.com/KSUTurf/status…

Crabgrass Germination: Do I put down preventer now?

With the unseasonably warm weather, we’ve been getting this question a lot lately. Crabgrass is an annual weed and must come back from seed each year. Since, crabgrass must germinate from seed each year, we can control crabgrass by applying a pre-emergent herbicide to the soil that will kill young germinating crabgrass seedlings. This is . . . → Read More: Crabgrass Germination: Do I put down preventer now?

Wild Garlic, Wild Onion and Star-of-Bethlehem

Ward Upham from the Hort Rapid Response Center had a great article in the Horticulture Newsletter. I’ve posted a copy of the article below.

Wild garlic (Allium vineale) and wild onion (Allium canadense) are two closely related plants that can become weed problems in home lawns and landscapes. Though wild garlic and wild onion . . . → Read More: Wild Garlic, Wild Onion and Star-of-Bethlehem

Some More Info on Possible Injury from Herbicide

I took a few pictures of some trees recently that appear to have injury at a site where Imprelis was applied. I also have spoken to several LCO’s and many are seeing possible Imprelis damage on more than just Norway Spruces and White Pines. I’m hearing reports of possible damage on;

“Clumps of tall grass in my lawn”

Over the past couple of weeks I’ve had a few calls and emails generally about clumps of fast growing grass in lawns. Generally, I see this mystery weed as 1 of following weeds.

Tall Fescue (K31 in a tall fescue yard, or tall fescue in a bluegrass, buffalograss, or Bermudagrass lawn) Orchardgrass in any lawn, . . . → Read More: “Clumps of tall grass in my lawn”

Knotweed Germinating in Newton

Today we had our Grounds Maintenance Workshop in Newton, KS.

And just outside the door in a nice, warm, heavily ‘trafficed’ spot was a nice patch of Knotweed.

Knotweed is a summer annual broadleaf weed. It germinates fairly early in the spring…earlier than crabgrass (which germinates earlier than goosegrass). I occasionally get calls . . . → Read More: Knotweed Germinating in Newton

Japanese Clover – Common Lespedeza –

I don’t know if two separate posts on strange weeds counts as “the summer of strange weeds.” But, it is definitely different. I took some pictures of a strange weed a few weeks ago, and as I was preparing this post I came across Dr. Nick Christians’ post about finding some bellflower in Ames. What . . . → Read More: Japanese Clover – Common Lespedeza –

Removing unwanted bermudagrass

The following is taken from the KSU Horticulture Newsletter, article by Ward Upham

Bermudagrass can make a nice lawn if you don’t mind its invasiveness and short growing season. But many people dislike both these characteristics. Warm-season grasses such as bermudagrass, zoysiagrass and buffalograss green up later than cool-season grasses such as tall . . . → Read More: Removing unwanted bermudagrass

The University of Arkansas has just published an excellent publication on the herbicide MSMA. As many of you know, the EPA has ruled that MSMA can no longer be used. Depending upon which segment of the turf industry you belong to, there are different rules for using MSMA for the next few years.
