Shasta daises have beautiful blooms, with full, double quilled white petals and yellow centers, that return every spring and summer, flowering until early fall.
These drought-tolerant plants are relatively low maintenance, resistant to rabbits and deer, and with few insect and disease problems, however, they also love to spread, so deadheading Shasta daisies isn't just to promote a longer blooming season, but also to stop them seeding.
Our experts advise the best practices for deadheading Shasta daises.

Deadheading Shasta daisies: when and how
Shasta daisies are the perfect low maintenance garden border idea or front yard flower bed addition for any garden. Deadheading your Shasta daisies regularly will improve not only how long they will continue to bloom for, but also the overall health and looks of the plant.
Should you deadhead Shasta daisies?
While your Shasta daisies won't die without deadheading, it is the best way to keep them blooming from summer to fall, improving their appearance and health.
Another benefit of deadheading Shasta daisies is that it will inhibit seed production. 'If left unchecked, shasta daisies have a tendency to self-seed, leading to a dense and overcrowded garden. Deadheading prevents self-seeding, allowing you to have better control over the plant's growth and distribution', advises Zahid Adnan, gardening expert and the founder of The Plant Bible
'As well as giving you a longer season of blooms, deadheading Shasta daisies will also neaten up the plant and keep it looking tidy,' adds Drew Swainston, gardening expert at Homes & Gardens. This will also mean the plant will rebloom healthily the next year.
When to deadhead Shasta daisies
Since the flowering season for Shasta daisies is usually between summer and fall, this is when you should be on the look out for spent blooms that need to go.
Shasta daisies grow in clumps, so it should be relatively easy to identify which flower heads are ready to be deadheaded, such as those that are turning brown or even have seed heads forming. These will be dragging the rest of the plant down, not only in looks but in consumption of energy and nutrients.
Zahid Adnan advises, 'As the gardening season comes to an end, you can perform a more extensive deadheading to prepare the plant for winter. This involves cutting back the stems to ground level once the flowering has ceased.'
How to deadhead Shasta daisies
Drew Swainston suggests, 'Select a spent flowerhead to remove and follow it down the stem to make a clean cut above a new bud, or a leaf joint. Make sure to use clean and sharp tools to deadhead (I recommend this Fiskars Bypass Pruner Garden Tool from Walmart); never rip or pull the flowers as you can damage the plant, and take care when deadheading not to damage any unopened flower heads.'
If all the blooms in a clump are spent, you can cut to the base of the whole plant.
Zahid Adnan says, 'At the end of the season, a more drastic approach is needed. Using sharp pruning shears, cut back the stems of the daisies to ground level. This ensures the plant goes dormant during the winter and comes back stronger in the following spring.'
