Grey Mold on Butterwort: Hydrogen Peroxide Treatment

Jay (Clackamas, OR) has grey mold on peat near a butterwort (from Lowe's terrarium). Asked about 1:50 water:hydrogen peroxide treatment. Plant in south window, distilled water, 50/50 peat:perlite (1 month).

Jeff Dallas: Media is actually long-fiber sphagnum (LFS), not peat moss (brown, from bales). Peroxide is fine—avoid pouring on plant. If using 3% drugstore peroxide, 1:50 is too weak; orchid growers use 1:3. Prevent mold: top-water to wash spores, spray sulfur fungicide (Safer).

Good Growing!
