Sow outdoors after all danger of frost has passed. Or, start indoors 4-6 weeks before the last expected frost and transplant seedlings.
Plant seeds individually or broadcast them over an area and thin them out as needed.
Brush an 1/8-1/4” layer of soil over the seeds, so they are just covered. Do not bury them – they need sun to germinate. Water the seeds directly after planting and then water consistently throughout the season. Too many flower seedlings will compete for nutrients and space, so be sure to thin them once they reach a few inches tall.
