Weeds becoming growing concern with spring

New Hampton, Iowa – Warmer temperatures and precipitation will spark new growth among weeds.

Brian Moore with the Chickasaw County Conservation Board says weed control helps bring growth to other plants if the weeds aren’t out of control.

 

One of the problem weeds are thistles.

Moore says thistles are one of the peskiest plants in Iowa and the Midwest because each plant has countless seeds.

 

You can dig up plants individually but if there’s a large patch of thistles, Moore recommends using a broad leaf killer.

 

The Iowa Department of Land and Agriculture Stewardship has a list of all weeds you should be aware of and what chemical is best used in getting rid of them.

Moore says a growing concern is around a new plant: palmer amaranth.   It’s similar in growth, shape and size to water hemp.

 

He adds the plant can produce up to one million seeds and is difficult to get rid of.
