Star-of-Bethlehem (Ornithogalum umbellatum)

This time of year all across Manhattan, KS we are seeing star-of-bethlehem popping up in lawns.  The reports that I get are from older lawns… Might be something I need to look into.  Maybe, this plant escaped from traditional landscape plantings and is now taking over the lawns?

It is a very pretty plant with showy, 6-petaled white flowers that have a distinct green stripe underneath. It is a perennial bulb that sometime appears to look like clumps of grass.  The leaves are linear and smooth, flat in cross-section and have a with midrib.

This plant also likes shady and moist areas of the lawn.  With the recent moisture and more on the way we are not short of moist areas in the lawn around Manhattan right now.

Although it is has very distinctive characteristics it can be confused with other plants that are commonly found in lawns; crowpoison (Nothoscordum bivalve), spring beauty (Claytonia virginica), wild garlic (Allium vineale) and wild onion (Allium canadense).

For chemical control there are couple of options.  Both sulfentrazone and carfentrazone have shown to be very effective.

Always remember to READ THE LABEL for the correct rate, turfgrass tolerance, and specific instructions before application!!!

Weed Control Update

As I look back through blog posts from Spring time in previous years, I notice a repeated theme – Crabgrass, Knotweed and Wild Garlic.

So instead of “reinventing the wheel this year” and writing a new blog post I am going to post previous years posts for these weeds.  There is lots of great information about these weeds and how to control them. (Links to information below the photograph.)

This way I can focus on adding a weed to this list that is become more and more persistent in Kansas. (Stay tuned!)

Stinks… Don’t It! – Wild Garlic Control In Turfgrass

Posted on by jahoyle

Garlic has a very distinct and pungent smell, stinks… don’t it!  But did you know there are benefits to eating garlic? It is highly nutritious but has very few low calories, it can help combat sickness, it can reduce blood pressure, and more.

Around Manhattan I have been seeing a lot of wild garlic in lawns. Now don’t go out and eat that wild garlic. We are now talking about the turfgrass weed wild garlic and not the garlic you eat.

Wild garlic (Allium vineale) is more obvious in the winter and early spring because this weed will grow above the turfgrass canopy and is easily noticed. Sometimes it can be easily confused with wild onion and star-of-Bethlehem.

Wild garlic is a perennial bulb that has a grass like appliance. It emerges in late winter and early spring. The leaves are straight and smooth. The way to tell the difference between wild garlic wild onion is by tearing the stem to see if it is hollow or solid. It if is hollow then it is wild garlic. If it is a solid stem then it could be wild onion.

This weed tolerate a wide range of soil conditions but I have noticed it more in low maintenance areas.

Control of wild garlic in cool-season turfgrass is more difficult then in warm-season turfgrasses.  For fair control use 2,4-D or one of the many combinations of 2,4-D, MCPP and dicamba.  This products have shown to have limited control.  The ester formulations of 2,4-D are more effective than amine formulations.  Applications in the late fall and early spring when there is adequate foliage is best.  To increase uptake, mowing before application may help.

In warm-season turfgrass metsulfuron or metsulfuron + sulfentrazone and sulfosulfuron provide very effective control.  Applying these products in late March early April on a warm day above 50 deg F when there is good soil moisture will increase efficacy.

If you got wild garlic, right now is the time to go out and get it.  Not to mention if you have any other broadleaf weeds you will get some control of those as well!
