Using Live Sphagnum in Water Trays and for Seed Starting

Live Sphagnum: Great for Seeds, Messy in Trays

A surplus of live sphagnum is a treasure—but don’t carpet your water trays with it. Over time it molds, clogs, and creates anaerobic pockets.

Better Uses

• Seed germination: Chopped live sphagnum is superb for Drosera rotundifolia and other sundews; whole strands work for Sarracenia.
• Separate culture: Grow sphagnum in shallow trays; sell or trade excess.

Leveling Uneven Windowsills

Use wood shims under trays—simple, effective, and standard greenhouse practice.
