How to plant: Propagate by seed, cuttings - Sow seeds indoors 12 weeks before the last spring frost. Do not cover the seeds with soil, as they need light to germinate. Until the seeds germinate, cover the seed trays with clear plastic to maintain high humidity. Water from below to prevent damping off. If large stock plants are available, cuttings can be taken in the spring. They root easily in potting mix. Pre-started plants are readily available at retail outlets. Germination temperature: 70 F to 75 F
Days to emergence: 14 to 21
Maintenance and care:
Pinch back the plants to keep them bushy. Keep medium moist but not soggy. Avoid sunny locations as plants will require too much water.
