Weeds

A. Yellow nutsedge is a warm-season perennial weed in the sedge family. The leaf blades are grass-like and triangular. It is usually a lighter green than lawn grass. Nutsedge thrives on moist, poorly drained sites, so it’s important to maintain a dense, healthy lawn and follow proper cultural care procedures such as mowing at the proper height, fall maintenance, and overseeding when necessary. If there are only a few yellow nutsedges present, you can manually pull them. Approximately six to eight weeks after emerging, the plants develop tubers or nutlets, so it’s important to pull them when they are young. After the nutlets develop, hand pulling will not remove the entire plant from the soil. Check back in a few weeks to see if the plants have regrown. When possible, dig out the entire plant removing the root system so it will not regrow from remaining roots. Yellow nutsedge can also be controlled using herbicides.

Corn Gluten Meal

Q. I have seen corn gluten meal sold as a pre-emergent herbicide. What can you tell me about it?

A. Corn gluten meal (CGM) is sold as a natural pre-emergent herbicide and fertilizer. CGM contains naturally occurring chemicals that suppress the growth of grasses and broadleaf weeds during germination. If you are reseeding your lawn, do not apply CGM, since it will inhibit the germination of your grass seeds. Since it contains approximately ten percent nitrogen, it also has an added benefit of fertilizing your lawn at the same time as inhibiting weed seed germination. The rate of application as well as the timing are critical for maximum effectiveness. CGM should be applied before weed seeds germinate in the spring—approximately late March to early April—followed by another application in late summer—approximately late August to early September. Make sure to follow label directions carefully.

Eliminating Weeds in Your Lawn

Q. I am concerned with the growing number of weeds in my yard. I have tried overseeding in the hopes of crowding out the weeds. Any suggestions would be appreciated.

A. There are many products available for spot-treating weeds once they have emerged. However, there are a few guidelines to follow, especially since you have recently set down grass seed. Apply the product when the weeds are young and actively growing. Do not apply on a hot or windy day, if the turf is stressed due to drought or if rain is expected within 24 hours. Avoid mowing your lawn for a few days before and after application. If you need to use the weed killers in your freshly seeded area, wait until that new grass has grown enough to be mowed three or four times. If you are planning to put down more seed in the area you have treated, wait 30 days before doing so.

Violets in Lawn

Q. How do I get rid of violets growing in my lawn?

A. Violets growing in the lawn are difficult perennial weeds to eradicate. At the present time, there is no effective chemical treatment that can be applied by homeowners. Only professional licensed turf specialists are able to purchase broad-leaved herbicides to control violets. Hand pulling is a tedious but effective option, providing that the entire root system is removed.

Feds Must Look the Other Way in Acquisition of First Medical Marijuana Seeds

It is illegal to transport seeds across state lines, so future growers must ask the feds to look the other way when they start their farms

As Illinois prepares to launch its medical marijuana program, the man with what some would say has the unenviable job of helming that launch says he believes the state has tried to think of everything to make certain that fraud is kept out and that the medicine gets to those who truly need it.

“We’ve really considered the difficulties other states have faced,” said Robert Morgan, the medical cannabis director for the Illinois Department of Health. “I think already we’re starting it as one of the most regulated programs in the entire country.”

In the process, the state developed rigorous standards, which require background checks of all employees, both at growing sites and dispensaries as well as 24-hour video monitoring of plants as they grow, with chain-of-custody requirements from the seed stage all the way to product delivery.

“From the moment they plant the seeds, we’re going to know where the product is,” Morgan said. “The volume, we’re going to know it to the ‘T’ of the actual clone to be able to trace back where that product came from to the sale to the dispensaries and the patients.”

Ahem. About those seeds.

You can’t transport them across state lines. You can’t ship them by FedEx, UPS or the U.S. Postal Service. You can’t bring them in from another country. After all, marijuana is, still officially, an illegal drug in the eyes of the federal government.

So how does Illinois deal with the issue of starting a new crop where the seeds cannot be brought into the state legally?

They don’t. Everyone has agreed to look the other way.

“We purposely left the bill silent,” said State Representative Louis Lang, the author of the medical marijuana act. “It’s either grown illegally in Illinois or brought in inappropriately.”

“Admittedly, the first seed is not technically a legal seed,” he said. “There is no way to write this.”

It’s being called the “magic beans” scenario. Once the plants begin to thrive, they will supply their own seeds, but before that, well, let’s just say that somehow they will come into being.

“All the federal agencies are really looking to the states to implement it in a strong way,” Morgan said. “But there continues to be tension with the federal government.”

Across Illinois, the state has received 159 applications for cultivation centers and 214 for dispensaries. Officials say they expect the first licenses to be awarded before year’s end.
