How do you make flowers last longer?

To make flowers last longer, choose the freshest flowers, trim stems at an angle with sharp scissors, use clean vases, and avoid direct sun or vents. Flower Boosters adds 40% extra days of vase life in real-world tests.

Does sugar water help flowers last longer?

Sugar water can help some flowers, but it's not reliable. The wrong concentration may cause wilting or bacterial growth. A balanced and tested flower food like Flower Boosters is safer and more effective.

Which flowers last the longest in a vase?

Carnations, alstroemeria, and chrysanthemums are known for long vase lives. Our lifespan chart shows how these and others perform with and without Flower Boosters.

How often should you change flower water?

Change flower water every 2–3 days if using plain water. If you're using Flower Boosters you can extend that to 3-4 days, or Just Blúme for roses allows for a once-a-week change while still keeping flowers fresh longer.

Can I return flowers to Costco if they die early?

Yes. Costco allows returns on flowers that wilt too soon, even after a few days. Just bring them back with your receipt and original packaging if possible.

How to Make Flowers Last Longer

June 11, 2025

If you’re wondering how to make flowers last longer, the secret starts before you even leave the store. Flowers can look deceptively fresh—but there are clues that reveal whether they’re still thriving or just holding it together until you get them home.

Flowers should brighten your space—not disappoint you the next morning. Let’s make your bouquet last.

Step One: Pick the Right Flowers

Flowers are often suspended in transit—chilled, packed tight, and treated to appear vibrant. But the minute they hit room temperature again, you find out the truth. Old flowers tend to fail fast.

Here’s how to spot flowers past their prime:

Trimmed buds or leaves: Retailers often remove fading petals to make bouquets appear fresher.
Mushy stems: A soft or slimy texture means the flower has been degrading for a while.
Discoloration: Browning on stems or petal edges is a clear sign of age or damage.
Musky smell: A sour or musty scent signals that decay is already underway.
No unopened buds: Flowers that have already fully bloomed may not last long.

If you can’t tick all the freshness boxes, skip that bouquet—no cut flower food can turn back the clock.

Step Two: Know Your Flower Types

Nature doesn’t play fair. Some flowers have naturally short vase lives, while others are underappreciated endurance champions.

The right flower paired with the right care can easily outlast others by a week or more—especially when boosted by a product that helps them absorb nutrients and fight off bacteria effectively.

Step Three: Treat Flowers Like a Living Thing

Think of flowers as house guests. Would you leave them soaked, sunburned, or in a draft? Here’s what not to do:

Don’t drown the stems. Too much water can promote rot.
Avoid direct sunlight or HVAC vents. Heat and airflow shorten lifespan.
Always use a clean vase. Leftover bacteria can take down fresh flowers fast.
Trim stems at an angle. This gives more surface area for hydration.
Use sharp tools. Jagged cuts make it harder for flowers to drink.

How to Make Flowers Last Longer — Internet Sugar Water Recipe vs Flower Boosters

Step Four: Feed Them What They Crave

Every flower has its own nutritional quirks—some thrive on sugar, while others wilt from it. Some prefer a higher pH, others lower. That’s why internet recipes can be hit or miss, and why free packets often fall short.

Flower Boosters is specifically formulated to support a wide range of flowers without guesswork. It delivers nutrients in a clean, measured dose—no sticky DIY mixes or confusing sugar hacks.

Love roses? Us too! That’s why we are introducing Just Blúme.
It’s formulated specifically for roses (and mixed bouquets that include them) and only requires one water change per week—keeping roses fresh and vibrant for 10–14 days.
