Arlington says its collected yard waste gets composted at a high enough temperature to kill weeds

If you put invasives in yard waste, pieces or seeds or whatever could get scattered around before the load reaches the compost facility. Less likely if it’s in trash.

But again, do they mean not home composted? There are a lot of things that can’t be done in a home-type compost that can be put in commercial compost (meat and bones is a good example).

OP you might need to contact them directly. It’s weird if that isn’t on their website (or that you’re getting conflicting info, it looks like? Sorry, i was never great on my Maryland geography and political boundaries).

I have always read that garlic mustard, once it has bloomed, should not be composted.

OP here. Yes, this is exactly what I'm wondering about. Also the folks who said the county won't pick up trash if green matter is visible. Thanks for the advice from someone above to put weeds in black bags so they can't see what it is when they pick it up. But I would hate to trash all this stuff (lots of it) if it turns out it would be composted at high enough heat to kill seeds. The county website doesn't say anything about invasives at all. You'd think that if it weren't permitted, it would be on the list of things that are not accepted?

If you put weeds in trash make sure you use the heavy black contractor bags so it cant't be seen. I tried putting them in regular trash bags and the guys insisted it was yard waste and wouldn't pick it up. (MoCo)

Might vary by municipality but good rule of thumb is to trash invasives once and for all.

Our trash won't be picked up if they see any yard waste in the trash can (MoCo)

I do throw english ivy in the ward waste bin.

It should be composted at pretty high temperatures in the county facility, so any seeds shouldn't matter.

You taught me something, OP. We put Japanese Stiltgrass in our FFX Co. yard waste and it never occurred to me that it might be a problem. My bad. Thanks, OP.

Does anyone know what DC does? I have a yard waste bag full of invasives and weeds...

This. Trash, not yard waste

Is it commercial? If it’s commercial, yes.

I'm hoping to pull a bunch of garlic mustard this weekend. Can I put it in the MoCo yard waste? Does their compost process kill all possible seeds? I'm assuming yes, but curious to hear if anyone has investigated this and knows the answer. I looked online but couldn't find much.
