Help Your Dahlia Blooms Thrive With This Important Task

Dahlias are a much-loved flowering plant among gardeners for their stunning blooms in various colors, shapes, and sizes. These flowers are not just beautiful, but also strong and resilient. To help them produce healthy blooms, it is recommended to remove their lower leaves.

This simple practice can make a big difference as it allows better airflow and helps conserve energy. With a little extra care, dahlias can transform any garden into a colorful paradise.

Why it’s beneficial to remove the lower leaves of dahlias

Growing dahlias? Im getting ansty for my blooms but it is better to top the plant and peel away the bottoms for bigger blooms lasting through the fall. #dahliatips #gardenergirl #growingflowers #flowertips #flowercare #dahliacare #zone7 #fyp #growingflowers

Dahlia enthusiasts understand that tending to these glorious blooms goes beyond admiring their beauty. Proper care ensures that your dahlias reach their full potential, including removing the lower leaves. Doing so allows air to circulate more freely around the plant. In turn, this improved airflow helps to keep your dahlias healthy and disease-free, preventing moisture buildup, a common trigger for fungal diseases like powdery mildew and botrytis.

Also, every leaf on a dahlia plant requires energy for maintenance. Removing the lower leaves directs the plant’s resources and energy toward producing more flowers rather than supporting leaves that may not contribute significantly to photosynthesis. To do this, it’s crucial to identify the lower leaves destined for removal before pruning, as demonstrated in the TikTok video of @romentaplants. These are the leaves closest to the ground and that often the first to show signs of stress or disease. Use clean, sharp scissors or pruning shears to snip the lower leaves. Aim to remove the ones touching the ground or those with discoloration, wilting, or signs of fungal growth. Make clean cuts to minimize stress on the plant.

The simple act of removing lower leaves is a critical step in ensuring your dahlias thrive. It not only helps maintain plant health but also aids in channeling energy towards producing those magnificent, vibrant blooms that make dahlias a perennial gardener’s favorite.
