Step 2: Rehydrate the Blooms From the Top Down

Hydrangea heads can absorb water
This is why rehydrating hydrangea blooms works so well.
Hydrangeas can take in moisture through the bloom itself, not just the stem, which is honestly kind of wild.
Use the sink soak method
Fill a clean sink or large bowl with cool water and gently submerge the bloom heads for 15 to 20 minutes.
Keep the stems out if that’s easier, or soak the full flower if your setup allows it.
Mist lightly or soak fully
If the bouquet is only mildly droopy, a light mist on the blooms can help.
If the heads are very limp, go straight for a deep water soak or submerging hydrangea heads, because that usually gives the fastest comeback.
Don’t overdo the soak
Too long in water can bruise delicate petals or sepals, especially on older blooms.
Once they begin to firm up, pull them out, shake off extra water, and get ready, because the next button below leads to the vase reset that keeps all your hard work from going to waste.
