If you were wondering how to grow flower mixes from seed, you've come to the right place!
When to Sow Outside: RECOMMENDED. In cold climates, sow flower mixes in the spring, 1 to 2 weeks before your average last frost date.
You can also sow half the seed mix 4 to 6 weeks before your average last frost date (hoping the last frost is earlier than usual), and then sow the second half a week or 2 after your average last frost date (just to be safe). The latest recommended spring sowing date is mid-June; after that time, conditions can be too warm and dry for germination and establishment.
In mild climates, sow seed during the cooler months. This will ensure an early display of annuals in the spring, and cool weather for germination and establishment of perennials.
When to Start Inside:Not recommended.
Special Sowing Instructions: Remove any weeds and amend the soil, if needed, prior to sowing. Rake the soil to loosen the surface. Shake packet before sowing to ensure even mixture of seeds. Using a rake, scratch in sand/seed mixture to a depth no greater than ¼".
Optional: Mixing seeds with sand can help spread seeds more evenly and the difference in color between the sand and soil can help remind you where to water.
Pro Tips: With a flower mix, it can be difficult to tell which of your seedlings are flowers and which are weeds. If you sow a pinch of seeds in a container of potting soil, you can then compare the flower seedlings with what sprouts in the garden. You may also try first watering a prepared area in order to germinate the weeds; then eliminating the weeds before sowing flower seeds.
