Zoysia Grass Dethatching

Greetings,

I have zoysia grass in my back yard, which is flat for about 10-15 feet from the house, and then goes up a rather steep hill. Some of the grass on the flat part is dying, and I am suspecting excess thatch is the culprit. When is the proper time to dethatch zoysia grass? And what about scalping the lawn to help it grow in the spring...?

Thank you,

probably the best time for dethatching is when the yard is actively growing, so probably for you the first part of June. However, i really doubt that this is the reason that your grass is dying, unless it is a horrible problem. Could it be staying too wet, and therefore diseased? if this is the case, the thatch could definitely be contributing to the problems.

How large of an area is this Zoysia patch?

I have a 1/2 acre of it (my front lawn) and when I dethatch (every other year) it is unreal how much thatch I have to haul away. I use a pull-behind lawn sweep to collect it and last Summer I hauled off 2 trailers (6.5 X 12) stacked full of it.

Be prepared. :D
