1. Start with a clean vase; wash a dirty one with detergent and a bottle brush, then rinse well.
2. Remove foliage that would sit below the water line to reduce decaying plant matter in the vase.
3. Recut the stem bases as appropriate for each species, handling cutting tools carefully.
4. Fill with clean water and add commercial cut-flower food only at the label's recommended dose.
5. Place the arrangement in a relatively cool area, away from radiators, fires and direct sun.
6. Check water regularly; replace it and trim stems every 2–4 days, removing dying blooms.
