Clematis Seed Germination Needs Cold; Cuttings Need Sterile Mix

Clematis seeds require 90-day cold stratification (fridge). Cuttings root in 8 weeks in sterile soilless mix (not compost) with humidity and bottom heat.

Soilless Mix

Sterile, well-draining (peat/perlite/vermiculite); prevents rot and disease. Buy or make your own.
