Propagation Masterclass: Water vs Moss vs Perlite for Root Hormones
The ultimate botanical breakdown on propagating stem cuttings with maximum survival rates.
Learn how auxin plant hormones trigger adventitious root formation in stem nodes. Compare water propagation against sphagnum moss and perlite boxes.
1. Anatomy of a Node & Auxins
When you take a stem cutting, plant hormones called auxins pool at the cut site. Auxins signal unspecialized stem cells to morph into adventitious root initials.
Without a node (the small bump where leaves and aerial roots join the stem), most cuttings will produce water roots extremely slowly or rot.
Adding a cutting of Golden Pothos to your water jar accelerates rooting for other plants! Pothos releases natural root-stimulating auxins into the water.

Water roots are thin and fragile, adapted to aquatic oxygen. When transferred to soil, keep soil moist for the first 10 days to help roots transition to soil-adapted structures.
