Be sure to follow instructions for packaged products.<\/p>\n<p>While nitrogen is not itself toxic, excess nitrogen in fertilizer is a problem. Plants can only take up a certain amount of nutrients at a time. If we apply too much at once, the fertilizer ends up in our rivers and lakes. That creates conditions for toxic algae that ruins the water for humans and animals.<\/p>\n<p>One way to avoid excessive nitrogen application is to time your fertilizing for when the grass is growing (late May and early October, for example). Use slow-release nitrogen or organic products. Calculate the amount you need using online tools and apply according to instructions. One such tool is <a href=\"http:\/\/bit.ly\/4nxd8Lq\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n<p>For large lots, consider contacting the <a href=\"https:\/\/extension.wsu.edu\/clark\/naturalresources\/smallacreageprogram\/\" target=\"_blank\" rel=\"noopener\">WSU Small Acreage program<\/a>, which offers workshops and training for weed control, maintaining planting pasture-type grasses, and more.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-24116\" src=\"https:\/\/wpcdn.web.wsu.edu\/wp-extension\/uploads\/sites\/2079\/2025\/09\/GUYL_Aerating_iStock-396x338.png\" alt=\"\" width=\"235\" height=\"201\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/wp-extension\/uploads\/sites\/2079\/2025\/09\/GUYL_Aerating_iStock-396x338.png 396w, https:\/\/wpcdn.web.wsu.edu\/wp-extension\/uploads\/sites\/2079\/2025\/09\/GUYL_Aerating_iStock.png 539w\" sizes=\"(max-width: 235px) 100vw, 235px\" \/><\/p>\n<p>Lastly, fertilizers that use phosphorus are seldom needed by lawns in our region.
