What about you ! Welcome to Premier |Lawns Videos.
Today we're going to be renovating this tennis court. Stick around ................
This tennis court is currently undergoing an attack of "take-all patch". Take all patch is caused
by a fungus which is commonly found in soil. It is also known as take-all root, and it does just that.
It is a fungus that kills all of the grass plant: roots, stolon, runners and leaves.
The disease is very damaging to bent grass lawns.
For our viewers in warmer climates such as America, Australia and New Zealand, it attacks
Saint Augustine, Bermuda and Zoyia. Today I'm going to be repairing the damage, and giving you
tips on how to stop it. If you enjoy this Video don't forget to SMASH that LIKE button for me!!!!!!!!!
It mostly affects soils that are ph 7 or higher, as such lawns with sandy soils
or golf, or bowling greens, are more at risk than lawns on heavier soils.
Thatch, and poor drainage can increase the potential for take-all infections therefore
minimizing the thatch layer, ensuring good drainage, and regular aeration are important steps to take.
Make sure to watch the end of the Video to find out how the lawn turns out !
Other things that may bring on the disease. Applications of lime,
lack of magnesium, top dressing with a sand that has a high ph level.
These trees that are around the edge of the lawn restrict the airflow that comes into the lawn,
and as a result most of the take-all patches are in and around the areas that are shaded, due to the
lack of air. This section of lawn has its own micro climate compared to the rest of the lawn. Before starting
this project, we took soil samples. Here in the UK, fungicide control is for professional use only.
Scarifying the lawn quite heavy gives us the opportunity to clear out all
the dead grass. There's large sections in this bottom corner that have been totally
obliterated by the take-all patch. Take-all patch is most likely
to attack a lawn during the summer months, and tends to fade out during the winter months.
It is recommended to apply manganese sulfate twice in late spring before the symptoms start, and again
in autumn, along with a good quality wetting agent.
Wimbledon switched to a hundred percent dwarf rye grass grass lawns in 2001, and they haven't looked back.
Our next job is to use this tool. It's called a drag mat, and it does
literally just that. It drags the seed down into the lines created from the scarification.
To look at it more closely, this side hasn't been dragged yet, and you can see
all the seeds sitting on the side.. However, when we bring our camera over here,
this section has been dragged in. There's not as many seeds sitting on the surface.
As I talked about a short while ago, we said about the trees creating the micro climate,
and Daniel's just finishing off the last pass with the the mat. This area has its own micro
climate, and this is where the take-all patch is worst, so we're gonna soil these areas now.
After we get all the soil leveled out, our next step is to apply seaweed .
The seaweed has got growth hormone, so it's going to get the grass seed off to a good start.
Using ammonia forms of nitrogen to fertilize, such as ammonia sulfate
are better for managing take-all, rather than nitrates.
