How To Keep Hydrangeas Fresh Longer
🌸 How to Keep Hydrangeas Fresh and Hydrated
Hydrangeas are one of the most breathtaking flowers you can bring into your home—but they’re also known for wilting faster than other blooms. The good news? With the right care and a simple trick using alum powder, you can help your hydrangeas stay fresh and full for days.
Here’s everything you need to know:
✂️ Step 1: Cut the Stems at an Angle
Start by trimming the hydrangea stems at a 45-degree angle using a clean, sharp floral cutter. This angled cut increases surface area and helps the stems absorb more water.
💦 Step 2: Place in Fresh Water Immediately
After cutting, immediately place the stems into room-temperature water. This prevents air bubbles from blocking the stem’s water flow—something that can cause early wilting.
🔁 Step 3: Change Water Daily
Keep your water fresh and bacteria-free by changing it every day. Rinse the vase thoroughly and refill with clean water to give your blooms the best chance at lasting longer.
🧂 Step 4: Dip Stems in Alum Powder
Here’s the secret:
Right after cutting, dip the bottom of each hydrangea stem into alum powder before placing it in water.
Why alum powder?
Hydrangeas naturally seal off their stems after being cut. While this protects the plant, it also blocks water from entering—causing the blooms to droop. Alum powder helps break that seal and keeps the water flowing, allowing your hydrangeas to stay hydrated and healthy for much longer.
