How Long Do Shasta Daisies Live?
Shasta Daisies
They will continue their vigorous bloom if mature clumps are divided every two or three years and the non-productive center of the clump is discarded. Shastas' twisted stems may limit their usefulness to small arrangements and bouquets. As cut flowers, Shasta daisies last a week to 10 days.

Just so, do Shasta daisies spread?

Shasta daisies grow 2 to 3 feet tall. They like full sun and a well-drained soil with a pH level of 7 or higher. Their roots spread until the plant forms a bushy clump, 1 to 2 feet wide. Home gardeners plant Shasta daisies in flower beds as single plants, in small groups or in masses.

One may also ask, do Shasta daisies need to be deadheaded? First of all, Shastas normally bloom in summer and will continue throughout fall if regular deadheading is performed. So yes, deadheading Shasta daisies (and other varieties) is a good idea. In fact, this simple pruning technique can produce heavier, longer-lasting blooms in daisy plants.

Considering this, do Shasta daisies come back every year?

The cheerful Shasta daisy is a classic perennial. Like clockwork, Shasta daisies return every spring or early summer and bloom until early fall. They are never invasive (like some consider roadside daisies to be) and they are terrific for cutting.

What is killing my Shasta daisies?

Cottony rot (Sclerotinia sclerotiorum) usually attacks Shasta daisies at the soil line. The fungus survives in the soil and spreads in humid, wet conditions, especially during cool spring or fall days when temperatures hover between 56 and 59 degrees Fahrenheit.

Should Shasta Daisies be cut back in the fall?

Fall Pruning
Cut the Shasta daisy plants back in the fall to 2 to 3 inches above the ground after the plants die back. In warm climates, the plants may stay green most of the year, and require pruning only to remove dead or straggly stems.

How do you keep Shasta daisies from falling over?

As the blooms fade you should deadhead them (remove them) to encourage the plant to continue blooming rather than set seed, and once the flush is over you should trim the plant back hard. Then fertilize it and keep an eye on the watering. With luck you will have another good flush of bloom later this season.
