Harvest Tips
Cut flowers in early morning when buds are just opening for longest vase life (8-10 days). Use sharp pruning shears and cut at 45-degree angles above outward-facing buds. Remove lower leaves that would sit below waterline. Change water daily and recut stems every few days. Deadhead spent blooms throughout season to encourage continuous flowering.
Fun Facts
