Kentucky bluegrass

By Florence Sessoms

In the first part of this series, I described what arbuscular mycorrhizal fungi (AMF) are and how they can benefit plants. In this post, I will discuss how AMF might benefit turfgrasses. Cool-season and warm-season grasses are both able to be infected with mycorrhizal fungi. A quick literature review showed that several benefits of AMF were observed with turfgrasses such as improved biomass, nutrient content, decrease in weed incidence and disease severity (Table 1).

The 2015 Cultivar Evaluation Results are now available and published online.  To view these results, click the “Cultivar Evaluation Results” tab under the Research section on the left of this webpage.  Clicking this link will initially bring you to the 2015 data page, but you can view archived data from 2007-2013 as well.  Study labels are preceded by the date in which that study was planted.  For example, “2011 NTEP Kentucky bluegrass” was established in 2011, but you will be viewing the most recent data if you are in the 2015 tab.

Previously I wrote about the different renovation options for fall seeding of lawns and about the various attributes of cool-season lawn grasses.  This week I wanted to discuss the mixtures and blends of grass seed that are on the consumer marketplace.  If you’ve ever walked into your local big box store or garden center looking for grass seed, the different products available can be fairly intimidating.  To be honest, I often have a difficult time finding the right mixture, because it only takes one bad ingredient to produce a poor quality lawn.  With that in mind, let’s take a look at several categories of grass seed mixtures that are available to you.
