So, just to assure [personal profile] randomdreams that his experience with Ailanthus isn't unique, there are small sprouts coming up everywhere in the septic field. Copper sulfate in the line hasn't discouraged it at all.


Mimosa tree seedlings are everywhere, as well.

There's a cluster of non-native thistles beside the road maybe a quarter mile away. I so want to apply a flame thrower. And the neighboring lot also has a big patch of vinca.

The latest issue of "Conservation Gardener" from the UNC arboretum has an introduction from the editor that described their battling with invasives on their small patch of North Carolina. The challenge was observed, the drop-in-the-bucket-ness, but the editor concluded that it's the way forward. Everyone doing their bit.

I know they are invasives that never should have been planted here, but mimosa trees are tied up with all kind of good small town memories for me. Even if they were particularly poor as kids' climbing trees.

I hate those things. They smell bad, they grow SO DAMN FAST, they poison the ground and kill other things around them, and it takes manic battling to fight them down. I tore out eight yesterday and today there are two new ones, one almost knee high. I'm not generally a believer in herbicide, but for them I make an exception, and even then only because it manages to slow them down enough that I can take a day off between poisonings.

That is, I think, precisely the problem with ToH: it stores so much stuff in its roots that it can come back easily from localized herbicides. When I have several appearing in an area or along a line, I get in there with a posthole shovel, one of the really narrow long ones, and dig down until I find the main root line connecting them, and extract it. Fine roots don't seem to return with any robustness, but the main root is gigantic and attaches to all these clearly nutrient-filled nodules branching off it.

F****** "Tree of Heaven". We have the $$^#%@%#%#% @%#^@%@% things all over here. They are one of the few things I will use weed/plant killers on. The other is Ivy.
