Dear listers,
Does anyone have any easy way of removing carpobrutus edulis? The area is about 50ft. by 9 ft. and it is very heavy to haul around. Underneath the vines is a thick pad of fallen leaves. Is this usable for mulch or soil amendment? There doesn't seem to be any earth worms in this area. Has anyone tried this as an amendment?
Grateful for any help on this.
Jane

I found this on The Wildland Invasive Species Team page:

2. Request for information on succulent control
From: Mike Kelly (mkellysd@aol.com)
Carpobrotus edulis, Mesembryanthemum crystallinum and M. nodiflorum can be easily controlled -- in my experience -- with 2% Roundup sprayed on. Since some always escapes control the first time around, a followup spraying is necessary after the extent of the original kill is known. On beaches and dunes in San Diego and elsewhere, we have seen a native seed bank express itself after the iceplant dies enough to allow light, water and heat to reach the seeds. The native plants grow right up through the dying and dead iceplant with no harm from the Roundup. A native seed bank may not exist in areas that were heavily disturbed before the invasion of the iceplant.
