Coady Florist Flower Care Guide
Written by Coady Florist - Cambridge Florist
I've been making arrangements since I was a kid, watching my dad work behind the counter on Cambridge Street. If there's one thing I hear more than anything from customers, it's: “The flowers were so beautiful; I just wish they lasted longer.” The good news? With the right care, most bouquets can stay gorgeous for 7 to 14 days and sometimes longer. Here's exactly how to do it. - Dan
🌿 Coady Florist FLOWER CARE GUIDE
A few simple habits can double the life of a fresh bouquet. Here's everything we've learned in over 50 years of working with flowers.
💐Wrapped Bouquets: The First 30 Minutes Matter
✅ Find a clean vase. Bacteria are the enemy of fresh flowers. Wash your vase with hot, soapy water before you use it, even if it looks clean. Old residue on the inside can shorten the life of your flowers significantly.
✅ Fill with cool, fresh water. Room temperature or slightly cool water is ideal for most flowers. Very cold water can shock tropical varieties like bird-of-paradise, but for roses, lilies, and everyday bouquets, cool water is perfect.
✅ Add the flower food packet. We include these with every arrangement, and they genuinely work. The packet contains sugars (which feed the flower), an acidifier (which helps water travel up the stem), and a bactericide (which keeps the water clean).
✅ Re-cut every stem at an angle. Cut about an inch off the bottom of each stem. Ideally, holding it under running water or submerged in a bowl. The angled cut maximizes surface area for water uptake and helps when the stems are at the bottom of the vase. This single step makes a bigger difference than almost anything else.
✅ Strip any leaves that fall below the waterline. Leaves sitting in water rot quickly and breed bacteria. Remove them before placing your flowers in the vase.

💐 Daily Routine:
Good flower care isn't a one-time thing. It's a short, simple routine that takes about two minutes a day.
✅Change the water every day or two. Fresh water prevents bacterial buildup. When you change it, rinse the vase too. If you have more flower food, add another half packet with the fresh water.
✅Re-trim the stems every day or two. Just a quarter-inch off the bottom keeps the cut fresh and the water flowing. Always cut at an angle.
✅Remove any flowers or leaves that are past their prime. One wilting flower in a bouquet can accelerate the decline of the rest. Pull it out as soon as it starts to go; it doesn't mean the whole arrangement is done.
✅Keep the water level up. Flowers drink more than you'd expect, especially in the first day or two. Check the level daily and top it off as needed.
💐Where You Put Your Flowers Changes Everything
❄️ Cool + Bright, Not Warm + Sunny
A sunny windowsill looks like a perfect spot for flowers. It's actually one of the worst. Direct sunlight accelerates the aging process rapidly. Think of how quickly a banana ripens in the sun versus the shade. Flowers are the same.
The ideal location is bright, indirect light, with good air circulation, away from heat sources. A kitchen table away from the stove, a shaded corner of the living room, or a bedroom with a window all work beautifully.
Here's a trick from the shop: put your flowers in the refrigerator overnight. Seriously. We keep our coolers at around 34–36°F for a reason. You don't need to go that cold at home, but a cool room at night or even the fridge for a few hours can extend their life.
Good Spots:
✅ Dining table (away from heat vents)
✅ Dining table (away from heat vents)
✅ Kitchen counter (not near the stove)
✅ Entry table or hallway
✅ Bathroom with indirect light
✅ Bedroom on a nightstand
✅ Refrigerator overnight.
A few cool hours overnight can add days to a bouquet's life.

Avoid These:
❌ Sunny windowsills
❌ Top of the refrigerator (warm)
❌ Near a radiator or heat vent
❌ Near a TV or electronics
❌ Drafty doorways in winter
❌ Next to a fruit bowl, especially apples and bananas. Fruit releases ethylene gas, which causes flowers to age more quickly. It's completely invisible and odorless, but it's real. Move the fruit bowl to the other counter.
🌱What Really Works and What Doesn't:
✅ A small amount of bleach (⅛ teaspoon per quart). This actually works. Bleach kills bacteria and keeps the water cleaner longer, which is essentially what the bactericide in flower food packets does. Use very sparingly; too much burns the stems.✅ A splash of clear lemon-lime soda
The sugar feeds the flowers, and the acid (citric acid) helps water travel up the stem — the same principle as flower food. Use a 1:3 ratio of soda to water. Avoid dark sodas; they can promote mold.

✅ Apple cider vinegar (1 tablespoon + 1 tablespoon sugar)
The vinegar acidifies the water and inhibits bacterial growth; the sugar feeds the flower. A reasonable homemade flower food substitute in a pinch.
❌ Aspirin
The idea is that aspirin acidifies the water, and acidic water travels up stems better. But the effect of one aspirin tablet in a vase of water is so minimal that it's barely detectable. Skip it or use one of the options above instead.
❌ Copper pennies
This myth persists everywhere. The idea is that copper acts as a fungicide. Pre-1982 pennies (95% copper) might have a tiny effect; modern pennies (97.5% zinc) do nothing essentially. Not worth the trouble.
The truth? No home remedy beats the flower food packets we include with your order.
