Planting & Growing Guide

Dahlias thrive in full sun and well-draining soil. Plant tubers after all danger of frost has passed, 4–6″ deep and spaced 12–18″ apart depending on variety size. Pinch plants at ~12″ tall to encourage bushier growth and more blooms. Provide sturdy support for taller stems. Water consistently (avoid waterlogging) and deadhead regularly to extend the flowering season. In cooler regions, lift tubers after frost, cure them, and store in a cool, dry place for replanting next year.
