Extended periods of cool, wet spring weather this year has triggered extensive leaf spot on lawns. This is a troublesome spring diseases on Kentucky bluegrass (especially common bluegrasses), fescues and other lawn grasses. Some leaf spot can be found on most home lawns in the spring, but it normally does not cause significant damage to the lawn. This year due to the weather conditions leaf spot has occurred and now in progressing into the melting-out phase. Leaf spot is caused by several different fungi.

Brooms, rakes, vacuums and/or high pressure hoses can help to get the silt and debris off the turf. Tilling the silt into the top few inches of soil will cause all kinds of surface drainage problems in the future so the silt must be completely removed from site. Once the silt has been removed, evaluate the turf damage. If the field has been submerged more than a few days the grass will likely be dead so new turf establishment will be needed. Continue reading

With the snow gone, pink snow mold is present on turfgrass, especially on immature, lush, succulent stands of grass seeded last fall. In general, snow cover was not of long enough duration this past winter for the development of gray snow molds. There are some situations where light damage of gray snow mold is present but these are limited to sites where snow was piled up for long periods of time or in snow belt areas.

We have received several questions recently about rolling athletic fields. What benefits, if any, does it provide? How often should a field be rolled? Does it cause compaction? Here are some thoughts on the practice of rolling and some tips on how to make the most of this operation.

With spring just a few weeks away, it’s time to start planning season fertilizer programs! We offer some information on soil test costs and nutrient sufficiency ranges for turfgrass, as well as a helpful table on calculating the amount of fertilizer needed based on nitrogen analysis..
