So then we will first be looking at take- all root rot disease, The fungus that is responsible attacks the roots and because of this the turf is not able to take up water and nutrients through the normal process. When this happens the turf begins to decline. To learn more about St Augustine grass clink this link. Grass-type.

Signs of take- all root rot

Signs are large irregular patches in the turf that turn yellow and these areas will soon be bare spots where turf once was, the fungus that causes this disease is most active during summer and early fall when the temperature is high.

Another sign to look for is turf has short rotted roots that cause the grass stolons to be easily pulled up from the ground.

Signs of Gray leaf spot

Gray leaf spot develops under moist conditions, signs are an off green and brown color, moist area in the lawn. The infected areas begin to enlarge because of this fungus and the grass also has purple margins, the affected area may also take on a grayish appearance that is caused by this fungus.

The fungus that causes this disease is most active during warm weather that is accompanied by high humidity, also at this point fertilizers that are nitrogen base should not be used as this helps to increase turfs vulnerability against this fungus.

Control methods

Use fungicides to treat turf area,  water early in the morning so that turf can dry. Only use fertilizers that are low in nitrogen.

Signs of Brown patch

Brown patch is another disease of St Augustine grass that is caused by a fungus, areas that are affected by this turf turns yellow and begins to wilt as the disease sets in, these areas also turns brown-red. When  turf that is affected is pulled on it comes up very easily

This is because rot has already set in, action should be taken immediately in order for turf to recover.

Control methods

Apply fungicides making sure to follow label direction, also do not use fertilizers that are nitrogen base only but use a balanced fertilizer that will help the grass to recover much quicker.

Bahiagrass

    As it happens, we have just had a lawn laid. Up until a few weeks ago, we had copious amount of rain here in the UK with much flooding. It had rained sinced the beginning of November and didn’t stop. We had to wait to have the lawn laid because the ground was too sodden to walk on. Now it’s been laid, we haven’t had a drop of rain and the turf is now shrinking back.
    We can’t believe we’ll have to water the lawn after having all the floods but that is what we’ll have to do.
    It’s quite cold here in UK at the moment, with the occasional frost. Daytime temperatures are around 50F Hopefully it will warm up.
    You seem to have a good knowledge of turf so thought you may be able to give us a few tips? Ches

      Hello ches thanks for the follow, lawns are like humans they need tender loving care as you know, Sad to hear that you have to water by hand but if you must then all of that effort will hopefully pay off. Because it is cold you don’t have to water as much. And when the weather warms up water deeply because this would encourage the grass roots to stay within the first 6-8 inches of soil, also it is a know fact that grass only needs water when they show signs like the grass itself begins to wilt, grass takes long to recover from foot traffic, and depending on what time grass you have like st augustinegrass, grass makes a crunching sound when walked on. Other tips would be mowing at the proper height, different turf requires different cutting height, fertilizing with 16-4-8 or some other type fertilizer that is formulated for grass. Hopes this helps, for more know how you can check out my website that deals with grass type. Again thanks for the follow and have a good day.
