Choose a location with light to partial sun. Ensure the soil is well-draining and rich in organic matter.
Direct sow seeds 0.5 inches deep, spacing them about 12-18 inches apart. Alternatively, transplant seedlings gently.
Keep the soil consistently moist and protect from extreme heat or cold during this period.
Water regularly to maintain moisture levels but avoid overwatering. Mulch around plants to retain water and suppress weeds.
