Mary Lou dahlias produce striking 5-inch egg yolk yellow blooms with an upward-facing habit, ideal for cutting and garden display. These informal decorative varieties reach 4 feet tall at maturity, offering substantial presence in borders and arrangements. Their warm, golden coloring complements mixed plantings while the sturdy growth habit makes them reliable performers for both experienced growers and enthusiasts seeking substantial seasonal color.
How To Plant Dahlias
To get your dahlias started, pick a sunny spot with soil that drains well. Dig a hole, lay the tuber flat, and cover it with soil about 3 inches deep. Hold off on watering for now. Once you spot some sprouts and a few leaves, it’s time to water, but keep it gentle to prevent root rot. It’s a smartto put the stake next to the tuber at the same time of planting, so you don’t accidentally damage it later on.
As the season goes on, give your dahlias some love with fertilizer and insect sprays to help them bloom beautifully and grow strong. In the fall, dig up the roots and store them over winter.
