Harvest Tips
Cut flower spikes in early morning when blooms are fully open for fresh arrangements. Cut about one-third of the stem length to encourage further branching and more blooms. Veronicas last 7-10 days in a vase. For continuous blooms throughout the season, deadhead faded flowers regularly by pinching or cutting them off.
