I reside in Southern CA. 2 years ago I removed all the rock landscaping and planted African Daisy. There now is a non-broadleaf reed that to my knowledge is a weed growing in the ground cover. I have a drip system installed and cannot use any garden tools to remove or dig up the reeds.
How can I quickly kill off all the vegetation and replant without time delay?
It is my understanding that RoundUp will not kill this reed.
The property is going to be sold soon. I was considering just laying down a thick layer of bark and letting the next buyer select the plants of their choice.
Can bark be laid over the groundcover?
This is certainly a "reed". There is a pond a couple miles from here. Neighbors do not have it.
Previously I was watering 5 minutes daily with the drip system only.
The reed grows in wet or dry conditions.
Only about 10-15 plants are in this 20 by 40 ft. area; however it has destroyed the appearance of the yard.
The drip system layout prohibits simply temporarily removing the system to use a weed wacker.
I have previously had excellent luck with the African Daisy choking out weeds.
This is my first time the Daisy failed me.
Because the property will be sold in a few months I don't want to invest much money in the yard.
The yard will not sell the property.
At least by laying down the bark or mulch will not disturb the drip system and the next occupant can plant in amongst the bark.
Thank you for the comprehensive answer to resolve this problem.
Locating the drip system tubing that is above ground would be almost impossible.
The description of the reed is--fluffy round green top with definite seeds; tall stem; and a base of wide thick grass growing in a ball.
The stem is resistant to cutting.
Several weeks ago I used scissors to cut the ground cover within an inch or two from the ground hoping to hide the reed.
I am not satisfied with the appearance and felt the thick layer of bark would be more effective.
I also know that killing vegetation involves more then just spraying with a high strength Herbicide. The ground must then be covered with plastic; then the waiting time for the vegetation to die and the soil to return to the proper PH for re-planting. Soil additives are also needed.
I just don't have the time to wait for all of this.
African Daisy should not be cut because the plant self-levels itself yearly. However, these plants are too young to self-level.
