How to Grow Nemesia
- 1). Fill a plant flat almost 3/4 full with seed-starting mixture. Sow the seeds and cover them to a depth of 1/4 inch.
- 2). Add enough water to moisten, but not drench, the seed-starting mixture. Stretch a piece of clear plastic over the plant flat and place in a dark location that maintains temperatures of at least 70 degrees Fahrenheit.
- 3). Check the growing mixture daily and add moisture only if the mixture no longer sticks to your finger. Remove the plastic and place in a warm, sunny location after the first seedling emerges.
- 4). Loosen soil in the planting location to a depth of 12 inches. Amend with 2 to 3 inches of organic compost.
- 5). Transplant the seedlings outdoors after they have developed six leaves. Plant at the same level they were growing before and water until the soil feels moist. Add 2 to 3 inches of organic mulch.
- 6). Water nemesia plants when the top 1/2 inch of soil no longer feels moist. Feed them two times each month with liquid all-purpose fertilizer, at the recommended dilution for outdoor flowers.
- 7). Pinch the tips of the plants back, before blooms start to develop, to encourage fuller growth. Cut the plants back by half in midsummer to stimulate another wave of blooms.
