Tips for Getting Cut Flowers to Bloom Even Faster
- Start seeds indoors 4 to 6 weeks before your last frost date.
- Use a seedling heat mat — speeds germination by 30 to 50 percent for warm-season flowers.
- Harden off properly — rushing transplants causes stress and delays blooming.
- Deadhead and cut often — the more you cut, the more your plants produce.
- Feed with a bloom booster fertilizer — low nitrogen, high phosphorus encourages flowering.
- Plant in full sun — at least 6 to 8 hours of direct sunlight daily.
How to Get the Longest Vase Life
- Cut in the early morning when stems are fully hydrated.
- Cut at the bud stage or when blooms are half to three-quarters open.
- Place stems immediately into clean, cool water.
- Strip all foliage below the waterline.
- Condition in a cool, dark place for 4 to 8 hours before arranging.
- Change vase water every 2 to 3 days and re-cut stem ends at an angle.
