How to Care for a Shasta Daisy
The Shasta daisy is a short-lived perennial hybrid of two different European daisies, and was created to be used for cut flowers. Each plant can reach up to 3 feet tall with a spread of 1-1/2 feet. White flowers with yellow centers appear in summer and continue through fall if proper care is provided. Foliage is dark green, lobed and often overlooked in favor of the attractive blooms. Shasta daisies are easy to grow in most areas of the United States, but may require special winter care in Northern climates.
Plant Shasta daisies in spring after all danger of frost has passed. Choose a planting location that receives full sun to light, dappled shade and has fertile, well-drained soil. Prepare the site by tilling to a depth of 12 inches with a garden tiller and incorporating a 2-inch layer of organic compost into the soil.
Dig planting holes twice as wide as the root ball and of equal depth. Place each Shasta daisy into a hole and gently back-fill with soil. Space plants 2 feet apart to allow adequate room for growth. Shasta daisies are typically available at nurseries in pots or gallon-size cans, which are easy to transplant into the garden.
Water Shasta daisy plants immediately after planting to settle the soil. Continue watering once per week during the spring and summer months, as Shasta daisies need moderate moisture but will not tolerate wet, soggy soil. Increase watering during very dry periods to twice per week, as necessary.
Feed Shasta daisy plants once per month during the spring and summer using a balanced fertilizer with a 20-20-20 NPK ratio. Refer to the manufacturer's instructions for the correct application rate. Water thoroughly before and after fertilizing to prevent root injury.
Remove spent Shasta daisy flowers as soon as they begin to fade to prolong blooming. Cut plants back to within 3 or 4 inches of the ground in September to stimulate growth the following season and help extend the plant's life.
Shasta daises perform best in full sun, except in areas where the summers are hot and dry. In these locations, choose a site that receives partial afternoon shade.
Apply a 2-inch layer of mulch around Shasta daisies in areas with harsh winters. When grown in warmer climates, mulching is not necessary.
Shasta daisies may require staking if they begin to droop due to their height.
