Nothing special, just some potting soil and some cups.
Fill up with dirt, make a hole and drop the Brownies in and water lightly.
I tried the burying a tote in the ground. I’m sure my Neighbor has shoots coming up…. I find them in my turf, but those get dealt with when mowing, but the flower bed… god they get about 12’ down it and I gotta keep on top of them.
I’m gonna give it one more year before I start actually trying to remove it. I pruned it properly start of last season and got great yields. Birds loved it haha.
