| | Re: Dwarf Hairgrass
My hairgrass experience was disappointing. I also got some of it planted too deep and it didn't grow well. Some was planted just right and it grew rapidly, but then it grew up out of the substrate, like it was a stem plant, with roots just dangling in mid water as the plant grew up towards the surface. I found I didn't like the plant all that much so I pulled it all out yesterday. By contrast my marsilea did extremely well, forming a mat of plants on the bottom. That one is a keeper for me.
