Essential Selection & Care Instructions
1. Cut Stems at a 45-Degree Angle in Warm Water
Sunflowers have thick, fibrous stems. Cut 1 to 2 inches off the bottom of the stems at a 45-degree angle under warm running water. This prevents air bubbles from blocking hydration. Change the water and re-trim the stems every 2 days.
2. Strip All Submerged Foliage
Sunflowers have large, fuzzy leaves that decay rapidly in water. Strip all leaves from the lower two-thirds of the stem. Leaving foliage below the waterline spoils the vase water, causing bacteria to build up and wilt the blooms.
3. Select a Heavy Vase to Prevent Tipping
Because sunflower heads are heavy, they can easily cause lightweight vases to tip over. Use a heavy ceramic or thick glass vase filled with plenty of water to act as a ballast, keeping the arrangement stable and upright.
💡 Bleach Water Hack
Add a few drops of household bleach to your sunflower vase water. Because sunflower stems are thick and organic, they create bacteria quickly. A tiny amount of bleach keeps the water crystal clear and free of odor.
🐱🐶 Sunflowers are Pet-Safe
Great news! Sunflowers are non-toxic to cats and dogs. They are one of the safest large-bloom varieties you can display in your home, making them a worry-free choice for pet-owning households.
