Strawflowers can be sown directly in the garden, or can be started indoors. Tiny seeds need light to germinate, so scatter the seeds lightly on the surface of the soil, pressing them in to the soil and just watering. Don’t cover them! Because strawflowers are susceptible to rot if they are in too wet of an area, ensure their soil is well-draining and avoid watering too often. Drip irrigation is good for these flowers.
Thin your plants when they are about 3” tall to 10-12” apart for good air circulation. Strawflowers don’t need a lot of fertilizer, but benefit from initial fertilization and compost. Otherwise, strawflowers can do without much tending besides deadheading spent flowers.
