How to Propagate Desert sunflowers?
Propagating desert sunflowers primarily involves seed sowing after the last frost. Successful germination depends on factors such as full sun exposure, well-draining soil, and temperatures around 70°F. Scarification of seeds may enhance germination. Difficulty is moderate due to the need for optimal conditions. To propagate, (1) scarify seeds by lightly sanding them, (2) sow seeds 1/4 inch deep in well-draining soil, (3) place in full sun, (4) keep soil consistently moist but not waterlogged until germination, and (5) thin out seedlings to prevent overcrowding.
