Cultivating Dahliadenali

To ensure the thriving growth and abundant blooms of dahliadenali, proper cultivation practices are essential.

• Staging: Dahliadenali blooms can be staged for exhibitions or special events by cutting them in the bud stage and allowing them to open gradually in a cool, dark place.

Common Mistakes to Avoid

• Overwatering: Avoid overwatering dahliadenali, as this can lead to tuber rot and reduced blooming.
