Shasta Daisies: Can I Plant Them In The Summer?

Shasta daisies are a hardy hybrid perennial flower that thrives in USDA hardiness zones 4-9 and prefers full sun, well-draining soil, and consistent moisture. They provide perky summer blooms with evergreen foliage that lasts year-round in many locations. To grow Shasta daisies, you can plant them in any reasonable soil, in full sun or partial shade, and keep them watered until established. Stake tall-growing varieties in spring and remove faded flower stems during the growing season.

Shasta daisies typically bloom from early summer to fall and can reach heights of 2-3 feet. To plant, sow seeds in containers in a cold frame in autumn or spring, and expect blooms after one. Plant them 1 to 2 feet apart, depending on the variety. Shasta daisies require very little care, so plant them in full sun or partial shade, don’t over-fertilize, and let them do their thing.

To start Shasta daisies, start them from transplants or divisions in spring or early summer, after the danger of frost has passed. Seeds can also be sown outdoors from early spring through summer. In most climates, plant shasta daisies during the moderate temperatures of spring or fall.

Shasta daisies are tough and tolerant but prefer well-drained soil and require full sun (at least six hours). They can tolerate part-shade conditions, but flowering will be reduced. Soil: Average to sandy soil works well for Shasta daisies.

Do shasta daisies come back every year?

Shasta Daisies are a perennial plant that can be propagated by dividing them every two or three years during early spring or early fall. To propagate, use a spade to loosen the soil around the plant, leaving the roots intact. Divide large clumps of the plant, cutting roots apart with a sharp spade, creating two or more pieces from the roots, leaving enough stems for healthy growth. Remove damaged or diseased root pieces and set divisions 10 to 12 inches apart in full sun for replanting.

To grow from seed, sow seeds indoors eight weeks before the final spring frost, cover with seed-starting mix, and keep them moist and at 70°F. Seedlings will emerge in two to three weeks, and should be placed under plant lights or in a sunny window. Harden off before transplanting them outdoors, gradually exposing them to more sunlight.

How do you keep daisies blooming all summer?

To care for daisies, trim off faded blooms, deadhead them for repeated flowering, and remove spent flowers to minimize mold growth. Keep root systems from overcrowding, dig them up in clumps every other year in the Fall, divide root balls, and replant separated plants with a spacing of 10-12 inches per section. Prepare perennial daisies for winter by cushioning mulch loosely around each plant, using extra taking not to cover the leaves. This product is not available in AZ, CA, HI, NV, and UT.

Can I cut back Shasta daisies in the summer?

Shasta daisies are a simple perennial that can be pruned in the fall after frosts have damaged their leaves and blooms. This pruning not only neatens up the garden but also removes old, withered foliage and flowers, making it easier for new growth to push through in the spring. It also discourages the risk of disease and pests overwintering and spreading. To prune shasta daisies, wait until the first frosts have hit and use clean and sharp pruners to cut them back to a couple of inches above soil level.

If you expect a cold winter, cover the area with mulch to protect the roots. Alternatively, cut them back once winter has finished, as leaving them until spring can provide food for birds over the winter.

How do you keep Shasta Daisies from getting leggy?

Shasta daisies are easy to grow and maintain, requiring only occasional water, moderately fertile soil, and sunshine. Pruning them helps prevent seeding and enhance plant growth. Gardeners with large patches of plants divide them every few years to increase the number and create a healthier clump. Over time, the stand will become bare in the center and the side stems will be leggy and fall over. To prevent this, divide the stand every three years and replant the peripheral pieces. Pruning during this process is confined to shortening the stems for ease of handling.

When pruning Shasta daisies, it is crucial to consider factors such as tools and skill, as the goals for pruning vary from season to season. Deadheading, a form of Shasta daisy pruning, helps keep seeding in check and plants looking their best. In spring, just before dividing the plants, pruning a Shasta daisy to 6 inches (15 cm.) from the ground will facilitate handling and get the plant ready for new growth. In the fall, cutting back the stems to 2 inches (5 cm.) from the ground after the foliage has yellowed is a common practice.

To ensure the hygiene of your tools, use sharp pruning shears or trimmers for cleaner cuts and frequent sterilization between pruning different types of plants. A 25 bleach solution is generally sufficient to remove any pathogens from your blades. Soak tools for several minutes, wipe with a clean cloth, and allow to air dry. Shasta daisies can withstand trimming at any point to remove spent flowers, dead or diseased stems, and minimize seeding. Pinching the tops of stems when they are 6 inches (15 cm.) tall promotes fuller plants and more blooms. Deadheading also encourages more flowers.

Will shasta daisies rebloom if you deadhead them?

Deadhead your Shasta Daisy plant to encourage it to bloom all summer and into the fall. Do this before the flower goes to seed, if possible. For best reblooming, don’t just lop off the flower head. Follow the stem down until you find a new bloom emerging, then cut just above the next highest leaf. If no bloom is developing, cut it about a half-inch above the ground. Attached are images that might help new to pruning/deadheading, showing where to find the emerging blossom, making the cut, leaving one leaf above the blossom, and two deadheaded plants. The blossoms will mature in two to three weeks.

Can you divide Shasta daisies in summer?

Shasta daisies can be divided every 2 to 3 years, with signs of division including fewer blooms, reduced plant vigor, or clump death. Plants should be divided in early spring or fall in warmer regions. Plants grown from clumps will bloom in their first season, while those grown from seed will flower in their second. Shasta daisies can be used in various landscape designs, including a shady garden, to create a visually appealing and functional space.

Can you transplant daisies in the summer?

The transplantation of Shasta daisies can be undertaken in either late fall or early spring, contingent upon the emergence of new growth. Spring transplantation may result in a slight delay in blooming, but it is preferable to divide overgrown perennials in the spring to promote healthier plants. The optimal conditions for transplanting are overcast or rainy days, although the presence of moisture in the soil may result in additional complications.

Why are my shasta daisies dying?

The AaMG community has provided information on the diseases affecting shasta daisies, including Phytophthora root rot fungus, Fusarium wilt, verticillium wilt, and rust. The disease is characterized by reduced growth, reddish-brown internal discoloration of some roots and lower stem, and more severe symptoms such as drooping rolled and dull-colored leaves, permanent wilting, and defoliation. If drainage cannot be improved, plants should be placed in raised beds 12 inches or more above ground level. Other diseases that affect shasta daisies include alternaria leaf spot, septoria leaf spot, botrytis, and powdery mildew. The treatment for these diseases is the same.

Cultural tips to help reduce fungal disease include sending samples to the Elliet Plant Lab testing, avoiding wet springs, and using raised beds 12 inches or more above ground level.

When can you plant shasta daisies?

Shasta daisies are a popular choice for their snowy white flowers, which require minimal care. To plant them, a hole should be dug that is twice the diameter of the root ball, and the soil should be placed into it. Subsequently, the soil should be gently tamped down, and the plant should be watered for a minimum of one week until it has become established. It is recommended that plants be spaced 1 to 2 feet apart, depending on the mature size of the variety. In the event that taller varieties are planted, it may be necessary to provide support by means of a stake.

Do shasta daisies bloom all summer long?

Shasta daisies, a European native, are naturalized in North America and return every spring or early summer, blooming until early fall. They can be aggressive growers, so choose varieties that don’t produce viable seeds or remove flowers before they go to seed. To prevent spreading, keep them contained in garden beds away from wild areas. Shasta daisies form clumps 2 to 3 feet tall and 1 to 2 feet wide, with all-white petals, yellow disk florets, and glossy, dark green leaves. They are great as cut flowers, as their blooms can last a week or more in arrangements.
