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, 1” deep, and 6-12” apart, in rows 30” apart. Water the seeds directly after planting and then water consistently throughout the season.

If planting directly outside, cover the area with netting or landscape cloth until they sprout. Birds love to dig them up for a snack!

Stagger plantings over the course of several weeks for continuous blooms.
