This is used as a soil conditioner which increases the soil’s capacity to hold water and nutrients by increasing capillary forces and cation exchange capacity – uses that are particularly useful in gardening.

Hanging Baskets
Sphagnum moss can be used in hanging planter baskets for flowers. The moss helps keep the soil warm and holds moisture in, keeping the soil from drying out as quickly. Sometimes, the moss is mixed in with the soil, for hanging baskets and in the garden, to aerate the soil and/or add acidity. Florists also use it for decorative and preservative purposes.

House Plants
Place a bit of this moss on top of a house plant’s soil helps keep the plant roots warm and the soil damp–by using sphagnum this way, you’ll cut down the need to water house plants as frequently.
