It was in pots with kitty litter, jumped the pots, so I just yanked it out of the pots plopped it down. There was some kitty litter left which kept the iris anchored. I have a small amount on the other side of the pond, I anchored them with some heavy rocks, the roots collect muck and finally anchor themselves.
Irises, at least the few types I've used, seem to do best when their rhizomes are above the water line. Also they do seem to need a fair amount of fertilizer. In smallish pots that might mean adding fertilizer.more often than when in a bed. This is all to get the biggest plants, most blooms, spreading plants.My irises are just not spreading on the shelf as much as they are in the bog.
I need plants that will grow out of a 6" water shelf. Parrots feathers and what else?
Using plastic wood like Trex or bender board you make what is basically a raised bed type structure, but with a couple of cross members on the bottom. Lower the pond level a bit below the shelf. Put down a bed of mortar where edges will be and set the structure into the mortar bed to level and fill the gaps between the uneven shelf and structure. Fill with whatever "soil" you want.Explain please.
I have a similar situation with yellow flag iris in a 100 gal stock tank bare root doing great and bare root on a plant shelf doing so so. Last year when cleaning the stock tank I noticed the iris roots where covered with muck . So thick I could not pass my hands through the roots . The roots in the pond are not covered with muck like the iris in the tank and stream. I wonder it the roots in your bog have collected muck and thrive off the nutrients that may be trapped.My irises are just not spreading on the shelf as much as they are in the bog.
Probably true. One point I was making here is 4 years ago I was looking for plants to go in a stream and would do well in less than 4 inches of water. I was referring to the other plants I listed that do well in the stream. Based on my zone, shade v sun those were the plants recommended to me from a plant web site. Pics worth a thousand words . With regards to the iris I was just showing what happened to my iris which was similiar to the OP.No iris that I know of requires shallow water. Sometimes seller will say something like 4" water. That's normally the maximum depth. Not sure if that's the case here.
Nice thinking...I started most of my marginals on our 10-12" deep shelves in pots. Eventually they all outgrew their pots so I just cut the pot off and plopped the whole clump on the shelf. The roots had grown around the dirt and gravel that I had filled the pots with, so the whole thing was rather heavy and didn't need anchoring. In several cases, I split the root ball down the middle so I had two half circles of plant mass and set those on the shelf with the flat sides up against the wall and the rounded side toward the pond. The plants then spread out from the root ball, so now it's hard to tell what started where. It's a pond jungle basically.
This method has been patented by me. Please mention my name anytime you copy it.
