Spagmoss™ 100% Premium Sphagnum Moss | 8L

A premium growing medium for epiphytes, propagation and potting

Besgrow Spagmoss is 100% natural sphagnum moss, sustainably harvested in New Zealand and compressed into a compact 100g briquette. Add water and it expands to a full 8 litres of fluffy, long-strand moss — ready to use as a growing medium, mounting material or potting component.

Its exceptional water retention and high air porosity make it well suited to Australian native epiphytes including orchids and ferns, as well as a wide range of propagation and potting applications.

Why it works

Sphagnum moss holds up to 20 times its weight in water, releasing moisture slowly so roots stay consistently hydrated without sitting wet. Its natural air porosity keeps oxygen moving through the root zone, reducing the risk of root rot. It is naturally low in pH (approximately 4.8) and low in soluble salts, making it gentle on sensitive root systems.

Classic Grade Spagmoss has strands of 100mm or longer in over 70% of the mix. It holds its structure well and does not break down quickly into a dense, compacted mass.

What to use it for

• Australian native epiphytes — an ideal growing and mounting medium for native orchids, elkhorns and staghorns
• Propagation and air-layering — encourages fast, healthy root strike on cuttings
• Orchids and carnivorous plants — the gold standard for hobby and commercial growers alike
• DIY moss poles and hanging baskets — long strands wrap easily around frames or line baskets

How to prepare

1. Place the 100g briquette in a clean bucket.
2. Add approximately 2 litres of clean water.
3. Allow 10 to 15 minutes to fully expand into 8 litres of usable moss.
4. Gently squeeze out any excess water before use.
