How to Care for Chrysanthemums
Chrysanthemums have a reputation as one of the longest-lasting cut flowers available — typically 7 to 14 days, well beyond what most bouquets manage. That reputation is genuine, but it isn't automatic. A few basic habits in the first few days after delivery make the difference between a bouquet that fades in a week and one that's still going strong two weeks later.

Right After Delivery: The First 10 Minutes
Trim the Stems
Cut each stem at a 45-degree angle using clean, sharp scissors, removing about 2-3 cm from the bottom. This exposes fresh plant tissue for better water absorption — stems that traveled dry or sat in a box for delivery benefit especially from a fresh cut.
Remove Lower Leaves
Strip any leaves that would sit below the waterline in your vase. Submerged leaves decay quickly and encourage bacterial growth that shortens the life of the entire arrangement.
Use Clean, Cool Water
Fill your vase with cool (not cold) water. If a flower food packet was included, use it — it provides nutrients and mild antibacterial agents that meaningfully extend freshness.
Ongoing Care: Days 2 Through 14
Change the Water Every 2-3 Days
Chrysanthemums are relatively tolerant flowers, but cloudy or discolored water signals bacterial buildup that will eventually affect the blooms. A full water change, along with a quick rinse of the vase itself, resets this.
Re-Trim Stems Every Few Days
Each time you change the water, trim another small amount off the stems. This removes any bacterial buildup at the cut point and keeps water uptake efficient throughout the flower's life.
Keep Away From Heat and Direct Sun
Place your arrangement away from direct sunlight, heating vents, and appliances that generate warmth (like on top of a television or near a stove). Heat accelerates the natural aging process significantly.
Avoid Ripening Fruit Nearby
Fruit releases ethylene gas as it ripens, which speeds up wilting in nearby cut flowers. Keep your chrysanthemum arrangement away from fruit bowls.
Basket Arrangements: A Few Differences
If you received a basket-style arrangement rather than a vase bouquet, the flowers are typically set in floral foam rather than open water. Check the foam regularly and add water directly to it as needed — foam dries out faster than a full vase and is easy to overlook since it's less visible.
Signs Your Chrysanthemums Are Past Their Best
Individual petals browning at the edges is normal aging — gently remove those specific blooms to keep the overall arrangement looking fresh, rather than discarding the whole bouquet. A genuinely spent stem will droop noticeably even in fresh water; that's the point to retire it.

Frequently Asked Questions
How long do chrysanthemums typically last?
With proper care, 7 to 14 days — among the longest vase lives of any commonly gifted flower.
How often should I change the water?
Every 2-3 days, along with a fresh stem trim each time.
Do chrysanthemums need flower food?
It's not strictly required but helps meaningfully — use any packet included with your delivery.
What's the most common mistake people make with chrysanthemum care?
Leaving submerged leaves on the stems, which decay in the water and accelerate bacterial buildup.
Can I revive a chrysanthemum bouquet that's starting to wilt?
A fresh stem trim and full water change can help partially, though individual browning petals are best removed rather than restored.
Is basket-arrangement care different from a vase bouquet?
Yes — basket arrangements sit in floral foam, which needs regular water top-ups and dries out faster than an open vase.
