How too Much Rain Affects your Lawn

In this post, we’ll review the most common lawn issues that are caused by too much rain.
We’ve had a very rainy spring so far. This past April has been the second wettest April on record, with 7.01 inches. The last time we got this much was rain was in 2011. Last year at this time we had only received about 9.55 inches. Our year to date precipitation is 17.14 inches. And it looks like we have more rain on the way.
We’re not the only one’s that suffers from the rain and being trapped inside. Your lawn also suffers when it receives too much rain.

Lawn problems caused by to much rainEffects of Over-watering

  • Surface Damage – Walking and moving objects like trash cans across a saturated lawn will not only compact the soil, but it can leave permanent marks or tracks in your yard.
  • Drown Grass Roots – Grass needs oxygen to grow, and excessive water will fill the air gaps in the soil, effectively drowning the plants.
  • Disease caused by fungus – Too much water can cause grass roots to rot and can lead to disease which starts off as yellow patches in your yard; once fungus sets in, little can be done except reseeding the dead patches in the fall.
  • Prone to disease and insects – When your lawn has a shallow root system, the grass becomes stressed, making it more susceptible to damage from insects and diseases.
  • More Weeds – consistently over-watering lawn can cause a lot of hard-to-kill weeds, but alas we can not control the weather.
  • Excessive Fertilizer Needs – Because your grass isn’t getting the nutrients it needs, you’ll have to use additional fertilizer to try and compensate.
  • Shallow Root Growth – Grass roots that don’t have to go far below the surface to find water can’t withstand drier conditions, leading to dead brown patches.

We all wish we can control but we can’t. We can, however, take steps to help your lawn get through periods of both rain and drought.
Make sure your yard has proper drainage.
After a rain storm, check your yard for puddles or standing water. If there are low spots in your yard, bringing in some fill dirt and reseeding the area can help. Also, make sure your rain gutters are clean and that the downspouts have extenders on them to direct water away from your home’s foundation. You can even install extenders that can be buried to form a french drain system that disperses the water underground instead of on your lawns surface.
Know when and how much to water your lawn
Basically, your yard should be watered deeply but infrequently. Here in Illinois, most lawns only need about an inch of water per week, and watering every day usually isn’t necessary. Letting the soil dry out between watering will encourage deep root growth and thick grass coverage, which means your lawn will withstand drought conditions better. You’ll need to adjust your watering plan throughout the season as your lawn’s water needs change.
