Rooting brugs can be difficult, some make it, some don't no matter what you do! I had more than 80 cuttings from my brugs this past fall, and I only have about 10 make it. Most of them got mushy. I had some in peroxide water, and I had some in water with moss around the roots. So far, most of mine that made it are in the peroxide water. This in only my second year growing brugs, and like everyone else, I think they are beautiful. So far, I have not met a brug I don't want to bring home! When I made the raised bed last year, I placed the water sorb crystals in the hle, then I placed the plants on that! I also placed a soaker hose through the garden, and that seemed to help so much, since we had such hot temps for last summer!
Good luck to everyone growing brugs this year. Make sure you post pictures!
