Q

I live in Riverton, and have areas in my lawn that are brown and sparse. I planted the lawn from seed, a Kentucky bluegrass blend I bought from a nursery, at least 10 years ago. It grows well in cooler weather, but by summer it looks dead in patches and is stiff, not soft lawn for the kids to play on. I would like to put down some patch seed, but don't know what kind to use and how is the best way to plant. Do I have to take out the old lawn or can I just sprinkle it on and cover with a little bit of soil. Also, is there any way to control the wide leaf weed that grows throughout my lawn as well as the entire neighborhood?

Answer(s)

A

Your lawn is a blend of grass species or varieties. Some are more heat-tolerant than others, and some are more cold-tolerant than others. The part that browns out in summer is probably not too heat tolerant, so you may want to over-seed now with a more heat-tolerant cultivar.

USU Extension's publication "Turfgrass Cultivars for Utah" will help you select the grass seed you need. The publication is online at http://extension.usu.edu/files/publications/publication/HG_Grass_2004_01.pdf

I cannot tell exactly what weed you want control recommendation for. You can either bring a specimen in to our office or send a digital photo of it to us; if we can identify it we can tell you the most effective control for it.

Good gardening!
