How to Propagate Rocky mountain zinnia?
(Zinnia grandiflora)
Rocky mountain zinnia, also known as Texas zinnia
Rocky mountain zinnia thrives when propagated by cuttings. Gardeners should select healthy stems for cutting, ensuring each possesses a few leaves. Cut at a 45-degree angle to increase surface area for root growth, and dip the base in rooting hormone before planting in well-draining soil. Consistent moisture and warmth will encourage rooting, with signs of growth typically appearing within a few weeks.
