Want your flower bouquet to stay fresh longer? Cut flowers naturally wilt quickly, but there's no need to toss them after just a few days. As someone who's relied on professional florist advice for years, I've found a simple, grandmother-approved trick that works wonders: add a pinch of baking soda to the vase water.

1. Fill your vase with fresh water.
2. Stir in a pinch of baking soda.
3. Arrange your flowers in the vase as usual.
With this easy method, your bouquet will stay vibrant and beautiful for much longer. It's straightforward, cost-effective, and far better than watching colors fade prematurely—especially for cherished gifts like roses, bubble bouquets, or even delicate poppies.
Baking soda acts as a natural antifungal and antibacterial agent. It inhibits bacterial growth in the water, preventing stagnation and keeping it clean for your flowers. Plus, it maintains an optimal, slightly alkaline pH that cut flowers thrive in.
- Scale the baking soda to vase size: a pinch for small, 1 tsp for medium, 1 tbsp for large.
- Cut stems at a 45-degree angle for better water uptake.
- Refresh water every 1-2 days, adding baking soda each time, and trim stems slightly.
- Wipe stems clean during water changes.
- Keep away from direct sun, drafts, heat sources, and ethylene-producing fruits like bananas.
