Planting Instructions:


Soil Preparation:

Remove weeds, large rocks, and litter from the planting area. Till the soil 10 - 12 inches deep and rake several times to break up large clods. It is best to do this when the soil is dry enough to not stick to garden tools. Loosening the soil will help the plant establish strong roots.


Optionally, start seeds indoors 4-6 weeks before last Spring frost. Harden off seedlings then transplant. Or directly sow seeds when soil reaches 70F in loose, fertile, moist, well-draining soil. Light exposure will increase germination. Add 1/2" - 3/4" layer of peat moss, sawdust, or potting soil to top of a mostly sunny and clear area. Broadcast seeds then water to push seeds into area. Keep moist until established. Adaptive, annual.
