My 7ft Tall Grass Died. Do I Need To Dig The Whole Thing Up?

Question

I had two patches of 7 foot tall grass on each side of my small decorative pond that died last year. They just never came back after I trimmed them back last spring. I would like to plant irises where they are at. I’m having a heck of a time getting down to dirt. It’s like I’m digging mulch. Do I need to dig all this out?

Answer 1

I would since you want to replant there soon. If you didn't plan to grow something else right away you could let it die out.
