Have you ever wondered where all the salt goes after the snow and ice melts from the roadsides and sidewalks? It turns out, most of the salt runs into the storm drain, but some salt will end up along the roadsides and boulevards in green areas.

Many plant enthusiasts have observed difficulty planting some plant species around black walnut trees. Black walnut trees naturally excrete chemicals into their environment to make themselves more competitive. This negative plant-on-plant interaction is known as allelopathy, and is more common in multiple plant species than was once previously thought.
There have been a few reports (Bertin et al., 2009; Bertin et al., 2003) of natural weed suppression in certain fine fescues (Festuca spp.).

NASA scientist Cristina Milesi estimates that there is three times the amount of turfgrass in the United States as there are acres of irrigated corn . When we consider that the rate of grass seed density required for turf can be up to 6 lbs per 1000 sq.ft, one can imagine the enormous quantity of seed needed to plant all that turf! Most of that planted grass seed is, at least here in the Midwest, Kentucky bluegrass. However, there is a grass genus that has gained interest and may one day be used just as much or more as Kentucky bluegrass.
Fine fescue turfgrass species are excellent alternatives to provide functional turf areas while reducing inputs of water, fertilizer, mowing, and pesticides. Eric Watkins recently received a $5.4 million grant from the U.S. Department of Agriculture's National Institute of Food and Agriculture to identify ways to facilitate adoption of these fine fescues on private and public landscapes.

Before I came to the University of Minnesota I had never actually seen a fine fescue golf green in person. I’ve always had the impression that fine fescue species could only produce a suitable greens surface in climates similar to Ireland, the U.K., or the Pacific Northwest of the U.S. Recent research, however, is helping me to realize that fine fescues could be suitable for golf greens in Minnesota (or similar Midwest locations) that want a lower input option.

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 int
