A bit blunt

IMG_1954So far in my campaign of grass eradication, Group and Conquer has given very satisfactory results so long as there is a ton of grass, and I let the grass rot down, mess it up, rot, mess it up again. I’ve made some developments.

In An off-site project, I mention the carbon bomb technique of using carbon heavy leaves to suck the nitrogen out of the ground rather than fresh or dried grass which is, comparatively, rather balanced between N and C, and so doesn’t suck up N near so well. I’ve added another element.

I have stones set on all the places I hope to plant Sunflowers (Helianthus annus) later this season. The small area of cleared ground under the rocks will be just enough to get them established. From there, Sunflowers have an allelopathic effect ( secretion of chemicals) that is specifically designed to kill grass. I will update with how effective it turns out to be.

Sheer mass, you see, opaque, heavy mass, does the deed of killing grass all on its own. To boost, it keeps the ground under it moist, rots the grass, attracts worms, insects, fosters lovely molds (yes, I am serious). Yes, sheer mass includes rocks, but I’ve found something even better.

I’ve observed that where old logs sit that they kill the grass under them because of sheer mass combined with the carbon bomb effect, but they also leave not only the grass dead, but the ground improved if they sit for awhile- most of the good due to the sheer mass effect I just mentioned, as I found in establishing my grain patch.

So rather than grouping grass to conquer grass, I’m trying grouping slices of logs to kill grass, and I’m quite pleased with the effects. Grass that once grew lush and green now rots yellow and moldy, a plethora of soil life attending to its burial needs, but there was no digging done.

A bit blunt, but it works.

The grass does grow up in the spots between the logs, but this can be fixed by tightly stuffing the cracks with grass, or, what I have been doing, just move the “pucks” around every week or so, and watch the grass disappear.

So if you have any trees come down, do use the thick trunk by cutting it in slices thin enough to easily move, but heavy enough to keep the grass pressed down, and be ready to stick some preferred plants in place of the no longer existing grass.
