How to Deal with Waterlogged Lawn

It feels like it’s been raining forever, doesn’t it? Those perpetual rain clouds have been hovering over many parts of South East Queensland lately, and our lawns are feeling the effects. Waterlogging is a major issue for both lawns and gardens. But fear not -  we are here to help you and your lawn weather the storm! Check out our tips below.

1. Keep Off the Grass

The first and most crucial step is to avoid walking on the lawn, especially in problem areas. Trampling wet soil can exacerbate the water logging issue. Also, consider trimming back the foliage of trees and shrubs. This allows more sunlight to reach the lawn, promoting better drainage. Keep an eye out for signs of fungal diseases, and if you spot any, use appropriate fungicides.


2. Drain the Swamp

If your backyard turns into a mini-swamp after rain, it’s time to address drainage. Here are some steps to consider:

  • Install a Drainage System: Consider adding a proper drainage system to redirect excess water away from problem areas.
  • Extra Drainage: If certain spots consistently collect water, create additional drainage channels or install trench drains.
  • Tree Removal: Sometimes, removing trees near waterlogged areas can significantly improve drainage.

Remember, the goal is to divert as much water runoff as possible away from the affected spots. 

For any large or serious drainage issues, we always recommend engaging with a qualified landscaper before beginning!


3. Year-Round Lawn Care

Combatting waterlogging isn’t just about post-rain activities. It’s essential to maintain your lawn throughout the year. Here’s how:

  • Organic-Based Treatments: Regularly treat your soil with organic-based fertilisers, organic matter, and soil conditioners. These enhance the soil profile and encourage beneficial microbes.
  • Favourite Products: We recommend fertilising products like Exceed, Lawn Kelper, and Lawn Blend.   
  • Spring and Summer Maintenance: During these seasons, consider aerating the lawn and top-dressing it with organic material. This helps improve soil structure and promotes healthy grass growth.

 

4. Dealing with Clay Soils

Waterlogging is common in soil with a high clay content. If you’re uncertain about your soil type, try this simple test: take a handful of damp soil and squeeze it. Here’s what to look for:

  • Sandy Soil: If the soil falls apart, it’s likely sandy soil.
  • Clay Soil: If the soil holds its shape and can be rolled into a log (similar to modelling clay), you’ve got clay soil.

Clay-based soils are great for holding water, so this can become a problem when there’s been a lot of rain, continuous improvement and using a clay busting product, such as gypsum or Garden Mate, is recommended. 

  • Garden Mate is a fast acting clay breaker with no need to dig it in, just water. Improvements can be seen 2-3 weeks after proper application. Repeat initial application 4-6 weeks later and then lighter applications 3-4 monthly after that. Garden Mate  creates softer soil and improves drainage, aeration and nutrient availability.
  • Natural Gypsum is a soft sulphate mineral composed of calcium sulphate dihydrate. It is beneficial for breaking up clay soil because it helps improve soil structure without altering the soil's pH. When applied to clay soils, gypsum can help reduce soil compaction, enhance drainage, and add essential nutrients like calcium and sulphur, making it easier for plants and lawns to grow.

 

 

Remember, a little care goes a long way in keeping your lawn thriving—even during the rainy spells!

Let’s hope the rain clears up soon, so we can focus on lawn care, mowing, and enjoying our lush green lawns without worrying about backyard swamps. Feel free to share these tips with fellow Brisbane residents dealing with waterlogged lawns.
