Shasta daisies, with tall stalks and large petals with yellow centers, are the most popular of the daisy-shaped flowers. This perennial bloom needs to be planted in a full sun location in your garden, in early spring. You won't see any daisies the first year of planting, but the second season will delight you with bunches of bright white blooms.
Prepare the soil. Dig up the planting area to a depth of 8 inches. Layer a sheet of compost, about 2 inches thick and work it into the soil. Compost will amend a soil that has too much clay, as well as, one that is too much sand. It also fills the area with nutrition for the new daisy seedlings.
Moisten the soil, but not to the point of making soggy puddles.
Plant the Shasta daisy seeds about an eighth-inch deep, in small bunches of five to seven seeds (1 to 2 inches apart). The bunches should be spaced at 6 to 12 inches apart. Cover the seed holes with soil.
Check the soil every day until the seeds germinate to make sure the soil stays moist. After germination (sprout pops through the soil) in 10 to 20 days, continue to sprinkle the plants, lightly, so as not to disturb the tender new roots.
Fertilize the new seedlings when they have reached 3 to 4 inches tall. Use an all-purpose fertilizer with equal parts nitrogen, phosphorus and potassium. Spread or pour the fertilizer during a watering session, so that the food readily reaches the Shasta daisy roots.
Use a fertilizer with higher phosphorus the following year in the spring, before the daisies bloom. The numbers on the fertilizer package will read 10-15-10 or similar. Phosphorus is always the middle number. This fertilizer type will encourage large, healthy flowers.
Control slugs and snails with organic methods, if you have them in your location. Copper sheeting around your garden area will discourage them. These are the only real pests that Shasta daisies are bothered with.
