I was hoping I would wake up this morning to find all the snow still piled in our lawns was just a cruel April Fool’s joke, but Mother Nature is for real this Winter!
It hard to think about green grass and flowers budding with 4-6” of snow forecasted for this week but it will happen, eventually! Today, I wanted to share some practices we can do to our lawns in the spring to ensure the turf we do have gets off to a great start and is properly prepared for the seasonal adjustments ahead. Before we dive into some of these things it’s important to remember getting on the lawn and working the surface to early can cause more harm than good. As a broad example; if the lawn is saturated from snow melt or spring rain, frost levels are still high within the soil, or early morning frost are still prevalent these would all be times to stay off the lawn and wait it out just a little longer.
1.) Spring Pre-emergent- It may seem odd to list this service first but my reasoning is to simply drive home the importance of this application. Getting a weed barrier in the turf prior to soil temps reaching the point of optimal germination for weeds like Crabgrass and Knotweed is crucial for many reasons. These include cost, overall spring weed pressure, appearance, competition with grasses.
2.) Raking- Snow Mold is something we deal with every Spring in Minnesota and often times we see this fungus grow and spread long after snow melt. One thing that can help with this is lightly raking these spots within the lawn. A light rake can help increase air flow drying out the leaf blades slowing down any fungus thriving in wet environments.
3.) Spring Aeration- I purposely have this practice ahead of Dethatching for reasons I mention below but also because aeration provides so many endless benefits it is something that should be considered having done every year at least once. Aeration, however, is a tough, rigorous process on the lawn and recovery time is something that should always be considered. Early to mid-spring is a time when cool season turf is actively growing allowing recovery to be quicker and less detrimental. By aerating in the spring, the goal is to increase water availability to the roots, increase fertilizer effectiveness, and drive roots deeper during a period of rapid growth.
4.) Dethatching- Thatch is needed in lawns within a reasonable amount. Without thatch our lawns would be hard and impact upon falling wouldn’t feel so great. It also breaks down over time keeping the microorganism in the soil active while producing nutrients for the grass, but too much thatch is not good. Too much thatch can block water and nutrients from getting into the soil and becoming a village of fungi. Finding the balance in dethatching is so important and issues can arise from having your lawn dethatched every spring. Typically, once every 2-3 years is adequate in most cases.
5.) Spring Fertilizer- For the most part early spring growth is all being fueled by carbohydrates stored from last fall or winter. With all those stored carbohydrates being used its crucial to always be sure those levels are full prior to summer heat and stress. With fertilizer in the spring that is our goal. Making sure the lawns is ready for what is ahead is always a more cost effective and sustainable approach to lawn care.
