Annual Surprise Mixture
Requires a rich and fertile soil with good drainage. Add plenty of organic matter along with a garden fertilizer (6-12-12). Prepare the soil and smooth the surface, breaking up any clumps. Sow the seeds evenly over the surface to carpet the area with plants, or plant clusters of two to three seeds for each individual plant you want. Thin the clusters to the single strongest plant after the seedlings emerge.
To sow tiny seeds evenly, mix the seeds with a few teaspoons of dry sand. Some seeds need light to germinate and should be left uncovered; simply press these firmly into the soil surface. Cover larger seeds with a fine layer of soil. After seeds are planted, whether covered or uncovered, be sure to firm the soil. Water thoroughly, but gently. It's important to keep the seedbed moist until the seeds germinate. Sprinkle the soil gently to avoid washing away seeds and soil.
When the plants are several inches tall, thin them to the recommended spacing. Use scissors to snip off unwanted plants without disturbing the seedlings you wish to keep. Continue watering until your young plants are well established.
