Harvest Tips
Cut flowers in early morning when buds show color but before fully open for longest vase life (8-14 days). Use sharp bypass pruners; cut at 45-degree angle just above an outward-facing 5-leaflet leaf. Remove lower thorns and foliage below waterline. Change water every 2-3 days and recut stems. Deadhead faded blooms to encourage repeat flowering throughout the season.
