Looking for ways to preserve flowers without losing their vibrant colors? Here’s a guide to making freeze drying flowers easy, so you get beautiful, colorful blooms that last for years.

What Flowers Can I Freeze Dry?

You can freeze-dry almost any flower that can fit into your freeze dryer. Of course, the exception would be poisonous flowers like Aconitum, Stink Lily, Angel’s Trumpet, and Morning Glory, to name a few.

How About Edible Flowers?

You most certainly can! Freeze-drying edible flowers are even better compared to drying or just freezing them. Isn’t it that one of the reasons why you add flowers to a dish is to add color and vibrance to your presentation? Put in a flower or two, and a boring dish can become exciting to eat.

By freeze-drying edible flowers, you preserve their natural colors and vibrancy. You won’t have any problems with wilting and discoloration. Even if the guests are late or the food preparation took too long, the flowers will still look fabulous for hours.

How To Prepare The Flowers

For small flowers like lavender, alpine blossom, amaranth, and celosia, you can keep them on their stems.

For flowers with big, beautiful buds like roses and zinnias, you cut out the stems just below the pedicel. This way, the buds fit into the freeze-dryer shelves without getting deformed or squished, and you keep the bud intact.

Freeze Drying Flowers: Wet or Dry?

Here’s her tip on how she was able to get the same results without waiting for the rain. What you do is dunk the flowers completely in water. Make sure all the petals get a good soaking. Then, take out the flowers and carefully shake any excess water off. Remember to leave some droplets in the bud when you shake them.

Do I Pre-Freeze?

If you just got your flowers fresh and dunked them in water, there may be no need for pre-freezing. You can just put the flowers on the tray and start the process.

Some do pre-freeze their flowers, especially when the weather is hot. Flowers can wilt easily, and the heat can ruin their appearance and color. If you live in a warm place and your freeze dryer needs time to cool down, pre-freezing can help lessen the heat damage. You have to act quickly to preserve as much freshness as possible. You have about a 45-minute window to work with for this.

Pre-freeze the flowers on the freeze-dryer trays you’re going to use so that you won’t have problems with condensation.

How To Freeze Dry Flowers

Flowers may look delicate and intimidating to freeze dry. But you’ll be surprised how easy it is to do.

  • Prepare the flowers as suggested above.
  • Turn on the machine and let it prepare itself. No need to adjust the settings; you can go with the pre-installed settings.
  • Once the freeze dryer tells you it’s ready, close the valve and put the trays inside the chamber.

The length of the time will depend on a lot of factors, such as:

  • The amount and size of flowers you freeze dry
  • Location of the freeze dryer. The process can take longer in a hot garage compared to a cool basement.
  • The season

Amazingly enough, the freeze dryer knows when the drying’s done. So all you have to do is press the button, and it will do the job for you.

How Do I Know That The Flowers Are Good?
