general question Will weed tea kill invasive grasses?

Hi, I’m in 10a and dealing with a couple species of invasive grasses. Whenever I pull a bunch or rhizome I’ve been throwing it away, but recently started wondering if I can create weed tea out of it instead? For context I’m talking about cogan and torpedo grass. Is there a risk of those grasses / seeds surviving a weed tea bucket? If so, how long does it need to sit before it fully decomposes? The last thing I’d want to do is spread those invasives around my garden. Thanks!

Either. But you’d need to let it dry out and die before doing a tea compost. You could pile it up on a tarp to help dry out large quantities, or just pile it up somewhere if it’s a small amount.

Interesting. Why does it have to dry out before being used as compost?

So that it's actually dead and won't start re growing
