Yellow Water LawnThought this might be a timely blog post given the amount of rain we have had. In fact, on farm, we have had 357mm (12 inches) since February 14 and 200mm (8 inches) in the 36 hours to February 26, 2013.

Given the amount of rain, even at home plus seeing the news etc, I thought I might explain some remedies for waterlogged lawns. Of course there are the obvious signs, like it actually being under water, but what is actually happening down there and how can you get your lawn in recovery mode.

With prolonged rain events your lawn is most probably getting long and in some cases getting thin as low sunlight levels persist and your lawn grows upright in search of the light. Whilst this is going on your soil is getting a hard time as well. If you are on a sandy loam soil, most of the nutrients are being flushed through the profile. In heavy soils the Ph is now starting to get very low and in time you will see mushrooms grow, moss on the surface of the soil and even yellowing of the leaf as some diseases start to creep in. These symptoms will be exaggerated if your lawn area is an already shady spot.

What to Do? Whilst is raining, there is not a lot you can do apart from look for suspect areas that are ‘pooling’ water from poor drainage. These will be the hardest hit areas and should take note of these spots so you can rectify them for next time. Once the rain stops and your lawn is dry enough to walk on, get the mower out. Give your lawn a good mow, catch the clippings and dispose of them. If your lawn is long, you might notice it is now a bit thin and you can see the dirt below. Don’t fear – after a few mows it will again start to mat sideways again. While it’s ‘open’ get some lime or dolomite and boost your Ph by giving the areas a good dose of it. Don’t worry about putting too much on and if you have done it correctly the lawn will be nice and white! Water in lightly as it will normally take a month for your lawn to get maximum benefit out of it. Once watered in you can also get back to your fertilizer program as your lawn will have lost a heap of nutrient.

It is not necessary to do this after every rain event, just when you see some of the signs of your soil saying it needs some TLC as well. This is only a general guide and if you want to be more exact, a proper PH soil test can be done using kits that are regularly available. As mentioned before, good drainage is the key so your lawn does not get waterlogged and rots the roots of your pride and joy so some aeration while the ground is soft as it will also go a long way to helping your problems.
