How to Dry and Preserve Carnation Flowers

Carnation flowers come from the Dianthus genus and are known for their sweet, spicy scent. Carnations make excellent cut flowers for bouquets and vases.

How to Dry and Preserve Carnation Flowers (Essential Tips)

When Are Carnation Flowers in Season?

Most types of carnations flower from late spring until late summer or early fall. Cut back your carnations after the first round of flowers finishes in early summer. This encourages a second flush of flowers later in the year. Deadhead carnations throughout the season.

When to Pick Carnation Flowers For Drying and Preserving

Pick carnation flowers (Dianthus) early in the morning or late in the evening. Plants contain more water at these times of the day, which helps the flowers last longer. You can harvest carnation flowers any time during the blooming season. Always use clean, sharp tools when harvesting carnations to prevent diseases from spreading.

How to Dry and Preserve Carnation Flowers

Air-Drying

Air-drying is the easiest way of drying carnations but takes longer than other methods. In addition, air-drying also causes the flowers to lose some of their color.

  1. Choose healthy carnation stems that have flowers that are fully open or almost open.
  2. Cut the stems off just above an unopened flower bud and remove most of the leaves.
  3. Tie the carnation stems in a bundle using string or an elastic band.
  4. Tie a length of string to the bottom of the bundle so that you can hang them somewhere to dry.
  5. Hang the stems in a cool, dark space. They will take about two to three weeks to dry.

Using a Microwave and Silica Gel

You can also dry carnation flowers by placing them in silica gel and microwaving them. This is quicker than air-drying, but you can only dry one flower at a time.

  1. Choose a microwave-safe container large enough for your chosen stem. You may need to cut the stems fairly short.
  2. Fill half of the container with silica gel. Silica gel can be bought as crystals from most hobby stores.
  3. Push the carnation stem into the silica crystals with the flower facing up.
  4. Carefully add more crystals to cover your carnation.
  5. Microwave the carnation in 30-second bursts at 50 to 60% power. Do this for approximately 2 to 5 minutes until the carnation completely dries.
  6. Take the container out of the microwave and put on the lid, leaving one corner slightly open.
  7. Let the carnation cool inside the container for approximately 24 hours.
  8. Remove the carnation and apply a layer of acrylic spray to help preserve the flower.
  9. Store your dried carnations in an airtight container until you’re ready to use them.

Pressing

Pressing is another easy way of preserving carnations, but it takes longer than microwaving them. You can use pressed carnations to make cards and other art projects.

Wrapping Up

Preserve carnations by air-drying them, microwaving them in silica gel, or pressing them. Dried carnations last for up to three years. Air-drying and pressing these symbolic flowers takes approximately three weeks. It takes about a day to microwave carnations.
