Start inside 8-10 weeks before last frost. Sprinkle the tiny seeds on soil surface and press lightly. Do not cover. Provide light and keep warm; 21-24°C (70-75°F). Water only from below and watch for signs of damping off. A fungicidal drench will also help to prevent damping off. Transplant 1 week after last frost. Space 4-6 inches apart in part shade to full sun. Must not dry out. Place plants at least 4 inches in from container edges. Shear overgrown plants to encourage bushier growth.
