Hi everyone,

I'm new here and relatively new to gardening. I just planted a large bed of iron plants (aspidistra) along with some border grass (liriope big blue) and a few hosta lillies. This bed is between two crape myrtles. Then I dumped a big bag of black Preen mulch on top. I picked the mulch at random and had no idea it contained herbicides.

I looked up on their website and can't get info about whether or not the herbicide is going to harm my iron plants or liriope big blue. The website says that lillies and crape myrtles are recommended for use with this stuff.

Is my new bed going to be OK? Should I go out there and remove as much of this mulch as possible? Will it harm my iron plants?
