Chufa Misadventure-AKA Nutsedge

Good things Chufa can be used for…

Plant it under non electric fencing, It only gets 12 inches tall, so no need to fit a lawn mower under the bottom wire/board. It does make a nice mulch, if you’d want to sythe and collect it.

Contain it in narrow areas between concrete, like patio and driveway.

Or maybe use it as I have, a cover crop so your workable garden area is smaller. Dammit.

Or maybe you need a place to store your tarps? Find some chufa to kill, it won’t be nesessary to find a new storge spot for a while.

As for some possibly useful information in my update, Chufa is still there, but sparse. I still need to stay on top of it to kep it under control. I think there is only one bed that I need to put cardoard on for spring. At least I can transplat through it and use the space.

There seems to be some confusion over the taxonomy. The cultivated chufa/tigernut is a specific botanical variety (Cyperus esculentus var. sativus) or possibly even a separate species, which doesn't set seed, and grows bigger tubers in a tighter bunch under the plant (as opposed to the far-reaching rhizomes of the wild variety) and so doesn't spread much. Here is an article from Cultivariable about it. Seems you have the wild variety. Hope you manage to get rid of the rest of it.
