Drying hydrangeas can help you enjoy them year-round rather than just for the short time that they bloom, and it's incredibly easy to do without using any harsh chemicals.

How to Dry Hydrangea Flowers

  1. Find blooms that are already semi-dry. For example, Annabelle hydrangeas bloom in a beautiful white and then turn a lime-green color, indicating that they're semi-dried out.
  2. Cut stems on a diagonal to make sure that your blooms have the longest vase life possible. Cutting stems diagonally gives them lots of surface area so that more water can be absorbed.
  3. Dip cut hydrangea stems into alum powder. Alum powder helps prevent the bacteria that seeps out through these hydrangea stems from making your hydrangeas droop prematurely. You can find alum in the spice aisle of most grocery stores. It's generally used for pickling, but it works really well with hydrangeas and keeping that water flow going up the stems.
  4. Arrange in a vase. Put the shorter-stemmed hydrangeas on the bottom. Use hydrangeas with taller stems for the next level. Put the biggest, tallest blooms right on top. The nice thing about hydrangeas is they can sit on each other and balance each other out. If you don't have the perfect shape right away, you can kind of play with the blooms until you get the shape that you like.
  5. Partially fill the vase with water until stems are submerged.
  6. Put the arrangement in a cool spot in the house. Keep your flowers out of direct sunlight and away from any heat sources.
  7. Add more water if it has evaporated but the flowers are not yet dry. In two or three weeks, they should dry out nicely!
  8. Once they start drying out, you can even give them a spray with some flower paint (don't use regular spray paint, because that'll kill them). Florists' spray paint is really good for when dried hydrangeas get older and lose a little bit of their color. I've got all different colors—pinks and greens—that I use to give blooms a pick-me-up.
  9. Once hydrangeas are dry, let the water evaporate completely.
  10. Decorate!

DIY Dried Hydrangea Arrangement Ideas

Dried hydrangeas look great no matter where you put them. Even just a few blooms in a vase can look beautiful on the dining room table or in a decorative wreath. But personally, I like to make a big arrangement and put it in my fireplace through the summer and spring.

If you have a fireplace, all you have to do is remove the grate and sweep out any ash. Then put your dried hydrangeas in an elegant vessel (copper is a fun choice) and pop the whole thing into the fireplace. I find it really brightens it up and looks really cool.

Since dried hydrangeas can last for a long time (up to a year in many cases!), you can try out a few different locations and see where you like them best.
