Grow Shasta daisy from seed or from a plant. When the daisy is full grown it will form a bushy clump were the stems grow up to three feet tall before producing flowers in the summer from July to September.
For healthy flowers with many blooms grow the Shasta daisy in full sun. However, if your summers are extremely hot with temperatures in the upper 90’s then the Shasta daisy would welcome part shade in the heat of the day.
Plant the flower seeds or nursery grown daisies in moderately fertile well drained soil. If you soil is poor, then amend it with miracle grow potting soil. You can plant daisy seeds indoors 12 weeks before the last frost in spring or sow seeds outdoors when the soil warms to 70 degrees.
For growing daisies in masses, turn over the soil with a tiller and plant seeds in rows; plant seeds 1/16 of an inch deep. Space the seeds sixteen inches apart.
Another way to grow Shasta daisies is to plant them with eye catching colorful flowers; coneflowers, zinnias and black-eyed Susan and red bee balm are a few of my favorites. All of these flowers can be cut for beautiful bouquets or floral arrangements.
Caring for Shasta Daisies
Water the newly planted seeds so that the soil is evenly moist but not wet. Do not allow the soil to dry out as it will cause the seedling stress. Seed germination occur in approximately 21 to 30 days.
Apply organic mulch around the flowers to help to retain moisture.
Keep the soil evenly moist but not wet throughout the growing season. The best way to achieve this is to water the flowers with a slow drip irrigation system in the morning. If you summer temperature is hot; high 90’s, then water in the morning and then again in the late afternoon.
Fertilize monthly with miracle grow formulated for flowers. I use bloom booster that is made to attach to the end of your hose. The fertilizer that is applied with water will get to the roots where the nutrients are needed. My Shasta daisies produce large beautiful blooms that are long lasting.
Deadhead the spent flowers to extend the bloom season.
