Martha Stewart's secret to long-lasting Dahlias? A rigorous deadheading routine that's surprisingly easy to follow

Martha stewart for miracle grow on a green background.

It's one thing to successfully grow flowers, but it's another to maintain them and extend their longevity.

Martha Stewart is showing us how to achieve the latter with her gorgeous Dahlias, which appear in full, lush bloom on her Instagram page.

'What’s an important part to keeping dahlias blooming all season long?' Martha captions the Instagram post. 'Proper maintenance and continuous deadheading to remove spent blooms, prevent plants from redirecting energy to seed production, and allow them to focus on making abundant and colorful flowers.'

Lucky for us, she walked us through the care process on her blog, and it's surprisingly easy to follow her example.

Martha's Dahlias range in color from pink, yellow, red, and white, but in the blog post, she drives home the point that maintaining their vibrancy comes down to attentive care practices. In this case, that means deadheading.

'...as the flowers finish blooming, when petals have begun to wilt, fade, or turn brown around the edges, it’s time to deadhead, or remove spent flowers,' Martha writes. 'Deadheading through the season prevents the plants from redirecting their energy into seed production, allowing them to focus on producing more flowers instead.

She continues, 'Deadheading also helps maintain the overall health of the plant, keeps the garden looking tidy and prevents the spread of pests and disease.'

Timing is everything with deadheading, though, so be mindful of your routine in the garden.

'To prevent wilting, when cutting, do so only in the early morning or late afternoon,' Martha writes. 'And only cut them after they open to mature size – dahlias will not open after cutting.'
