When spring weather is warm and settled, and nights are reliably above 50°F (10°C), prepare planting area by removing all weeds, grass, stones and large clumps. Loosen the top 2 inches of soil with a digging fork or shovel, then smooth with a flat rake.
Scatter mix thinly and evenly. Using your rake, work to cover the seeds with 1/2 inch of soil, then use planting mix or compost to cover any exposed seed mix. Water thoroughly with a gentle mist.
Protect tiny seedlings from birds by using netting or ribbons of shiny, reflective flash tape at planting time. Keep weeded and watered; when 3 inches tall, remove covering and thin seedlings to 8-10 inches apart for good air circulation and enough elbow room to grow, branch and bloom freely.
