Diagnostic Tidbits (Week of August 13) - Aug 20, 2012
by UW Extension Plant Health Clinic Team
Listed below are this week's plant diagnostic and growing tips from the Plant Health Clinic team.
Question: My lawn has greened up again with the recent rain but there are some dead spots.
Answer: We have had issues in NE Wisconsin with chinch bugs, necrotic ring spot and summer patch. Larger dead spots may the result of undesirable species of grass, areas with poor soil or a weakened lawn due to other stress factors before or during our drought conditions. For more information visit Doug Soldat, UW- Extension article Dealing with Drought Affected Lawns. Lawn issues can sometimes be a bit complex and we would suggest contacting the Extension for consultation (Plant Health Clinic). More often than not small dead spots will naturally fill in with existing Kentucky bluegrass. Larger spots may require a good raking followed by a layer of compost or quality topsoil and the planting of Kentucky bluegrass in the first week of September. Realize that it can take up to three weeks for Kentucky bluegrass to germinate. Alternatively, sod the area.
