i have rid several lawns of kikuia and paspallum by using sulphate of amonia only ..never put super phospate or lawn fertilizer on..over the winter and spring months i will every month give a real heavy dressing of sulpate of amonia it must be done while raining or it will burn the lawn be prepared the grass will grow like crazy but the troblesome weeds and kikuia and passpallum will outgrow themselves this is much better than spraying copletely out and having to resow

the way to kill kikuya is to mow the lawn down to the dirt for a while. The weed depends on the long growth for life. A friend did this and it killed it allright but they ended up with a lawn full of dandelions.. What a laugh that was.
you are right bobbity about cutting the lawn short but i would tend not to shave it at this time of the year but i use a leaf rake to tease the longer runners up before mowing or any other parts where the grass is laying flat like other things you have to keep at it there is no quik fix remedy but most of the kikuia shold be gone in 6 months

Kikuya is very hard to get rid of but persistence works. Does anyone know an easy way of getting rid of couch grass?
heather couch grass is an easy one if you have nothing in the particular plot spread sawdust about 11mm deep over the area the coch grows into that and can be rolled up like a mat if its in an established area its down to plain old hard work with a fork i have not had dealings with couch for some years it could be possible there is a spray for it now
heather i have just checked on internet on google type in how to kill couch grass there are several good sites on that hope this all helps
Heather, I found couch much harder to deal with than Kikuyu. ( correct spelling ?...a japanese word I thimk)
When it is coming out from concrete bases etc it is even worse.
Hi Blinky, I told that story to show it was the wrong thing to do at that particular time at least...we had to laugh at the state of the lawn though..He's never done it again and the kikuyu has crept back over a long period of time.
Would you believe that a lady who was visiting the area loved the kikuyu lawn so much that she took some down south a bit and put it in her lawn. My 1st thoughts were, ?but what about her neighbours"...!
Well Bobbity that's the problem with the couch...it is coming up from under a neighbouring fence!
You are correct about the kikuyu spelling and thanks I love to get my spelling right! Just shows you our terrible Kiwi way of pronouncing some words. However much it sounds Japanese, the grass is from tropical Africa. One point each LOL.
i had to laugh when i saw the spelling correction thanks for that i am on the coast at papamoa and know of 2 people right on the beach front with 100% kikuyu lawns and they are great mind you they have no gardens
Good one Heather...how strange , it is a south African word then.
i'm glad you have a good sense of humour Blinky. A lot of people think it is a maori word.
Heather, you do indeed have a problem with the couch then. What about tin buried deep to prevent the shoots from coming into your yard. That would be such a massive job tho' and there is no guaratee that the couch wouldn't go deep down and spread anyway. I have seen the masses of roots go very deep.
Sounds like poison is the only option, but even that is a temporary fix.

KIKUYU in the lawn.
If it's necessary to spray Kikuyu in the lawn March-April is the only time as this is when it's at it's highest growth rate. As the ladies said, it's a African plant and thrives in the hot weather.
The chemical to use is Roundup pre-mixed with a few mls. of vege oil before dilution with water. As vegetable oil is a natural plant oil it assists with chemical uptake within the plant. Dilution rate is 1 liter of Roundup to 100 liters of water, or parts thereof. Seeding of the sprayed lawn can be done when the chemical is dry on the sprayed area. Then with a stiff broom, broom the area sprayed and seeded, this then will dislodge the lawn seed down below the Kikuyu leaf area so that as the Kikuyu defoliates the lawn seed germinates thus no huge, ugly, mud patch.
Remember, Roundup has NO effect on seed....it's effective on GREEN PLANT TISSUE only.
