How to Harvest Flowers for the Longest Vase Life

Tips from a flower grower on when to cut, what tools to use, and how to make your blooms last longer.

There’s something deeply satisfying about harvesting flowers from the garden and bringing them indoors. But if you want those blooms to last more than a day or two, when and how you harvest flowers makes all the difference.

At Blomma Flower Co., everything we cut is done with vase life in mind—whether it’s a rose, sweet pea, or something wild and delicate. Here’s how to make sure your flowers last as beautifully in the vase as they do in the garden.

🌿 1. Cut in the Coolest Part of the Day

Early morning or just before sunset is ideal. Flowers are most hydrated when temperatures are lower, and stems haven’t lost moisture to the heat of the day. Avoid cutting during full sun, especially in June, when heat stress can shorten vase life dramatically.

✂️ 2. Use Sharp, Clean Tools

Always use sanitized, sharp clippers or snips. Crushing stems with dull scissors prevents proper water uptake and invites bacteria into the stem. A quick wipe with alcohol before you head out to harvest can keep your blooms fresher, longer.

💧 3. Bring a Bucket of Water With You

Especially in the heat of summer, don’t wait until you're back inside to hydrate your stems. Bring a clean bucket with cool water into the garden and plunge each cut stem in right away.

🌸 4. Know the Right Stage to Cut Each Flower

Different flowers have different ideal harvest windows:

• Roses: Cut when outer petals just start to reflex, before fully open

• Sweet Peas: Snip when two blooms on a stem are open, with one or two buds

• Peonies: Harvest in the “marshmallow stage”—when buds are soft but not yet fully open

• Snapdragons: Harvest when the bottom 1/3 of blooms are open

🧼 5. Strip the Foliage

Remove any leaves that will sit below the waterline in your vase. This simple step helps prevent bacterial growth that can clog stems and cause early wilt.

🏡 6. Let Flowers Rest Before Arranging

Give flowers a few hours in a cool, dark place in clean water before designing with them. This post-harvest rest rehydrates and conditions them to last longer in a bouquet.

🌼 The Garden-to-Vase Difference

When flowers are harvested with care—and at just the right moment—they don’t just look better, they live longer. That’s the difference between grocery store blooms and something grown with intention.
