How to Propagate Plumeless thistles?
Primary propagation of plumeless thistles is typically through seed sowing. Key factors for success include full sun exposure, temperatures between 15-20°C, and well-drained soil. Special considerations involve handling their spiny nature and ensuring good seed-to-soil contact. The difficulty level is moderate, though germination rates can vary. To propagate, stratify seeds if necessary, then sow directly in situ or in pots in spring. Keep the soil moist until germination, then thin out seedlings for optimal growth. Transplant if started in pots, once seedlings are robust enough.
