Pre-treatment: Seeds are soaked in water for 3 to 4 hours to remove any inhibitors and allow full imbibition prior to sowing. Seeds are directly sown into containers using a growing medium of 2 parts sand, 1 part mulch, and 2 parts perlite. Osmocote time release fertilizer is incorporated into the medium at the approximate rate of 22g per 6l PVC containers.
Establishment: Seeds are hand collected during the summer months when achenes matured. Hymenoclea salsola is common in the Mojave and Colorado deserts in sandy washes and rocky places; from southern California north to San Joaquin Valley and east to Nevada, Utah and Arizona and south to Lower California.
