Harvest Tips
Cut flowering spikes at the base with sterile pruning shears once flowers have faded completely. Some spikes may rebloom from latent buds if cut above a node, but cutting all the way to the base encourages plant energy toward next blooming cycle. Enjoy cut spikes in a vase filled with room-temperature water for 2-3 weeks indoors.
