Start seeds indoors 6 to 8 weeks before your last expected frost date. Sow seeds on the surface of moist, well-draining seed-starting mix and keep them in bright, warm conditions around 70 to 75 degrees Fahrenheit. Seeds typically germinate within 1 to 2 weeks. Maintain high humidity during germination, which encourages faster sprouting.
Harden off seedlings over 7 to 10 days by gradually exposing them to outdoor conditions. Transplant outdoors after the last frost date has passed and soil temperatures consistently reach 60 degrees Fahrenheit or warmer. Space plants 15 inches apart in full sun. Handle seedlings gently, as they can be delicate during the transition.
Sensitive Mimosa requires minimal pruning due to its compact, upright growth habit that naturally stays neat and shrubby. Remove any dead, damaged, or yellowing stems as they appear to encourage continued blooming. Pinching back stem tips early in the season can encourage bushier growth if desired.
