I think that we have to learn that stuff by experience. I have not found pachysandra to be as quickly rerooting as ivy, so I think that soil is safe. I wouldn't put either one in a compost bin unless it was absolutely without question dead, and the same goes for honeysuckle. I am not cursed with buckthorn, thank God, but from what I've heard, it's a disaster, so I wouldn't compost that either - the leaves of all of those are safe, obviously.

If your compost is super-hot, maybe it would be safe to compost all of these, but why take a chance? Put it in the trash, which is what I do with things that I know will keep coming back.

Agree with the above :-) That is how I approach controlling English ivy and yellow archangel, both of which are rampant in my inherited garden.

There's always the bonfire method. Pro tip: don't warm your hands over it when burning poison ivy.

I'm sure theparsley was making a joke, but I just have to say do not burn poison ivy!!! Bad news if you (or someone downwind) inhale the smoke or get it in your eyes.

I don't have any experience with pachysandra, but I suspect many people are way overcautious about their compost based on rumors rather than real experience. I've composted tons of English ivy without any regrowth issues at all. I just tore out some more today and threw it in a bin. I'll add oak leaves, grass clippings and kitchen scraps over time, and it breaks down normally. But I have been known to screen my finished compost with quarter inch hardware cloth, and this always yields a beautiful dark and spongy material in which no ivy roots or leaves are identifiable.

I am not basing my decision to keep English ivy out of the compost based on rumors, but rather based on the fear of the blasted ivy showing up elsewhere in my yard. Yes, maybe it will rot away merrily, but I am not taking that chance that some little bit will take root somewhere in my yard. I treat ivy the way I treat bindweed and other thugs - out in the trash.

lazy- things like morning glory and nastursium have tons of seed that will go wild wherever they land! Nancy
