How to Dry Dahlias Flowers: A Comprehensive Guide

by Jennifer

Dahlias are beloved for their vibrant colors and intricate petal formations, making them a popular choice for floral arrangements and garden enthusiasts alike. While their beauty is ephemeral, drying dahlias offers a way to extend their lifespan and enjoy their charm long after the growing season has ended. In this guide, we will explore the art of drying dahlias, from selecting the perfect blooms to preserving them for future use.


Selecting the Perfect Dahlias for Drying

Before embarking on the drying process, it is crucial to select dahlias at the peak of their beauty and freshness. Follow these tips to ensure you choose the best blooms for drying:

1. Choose Healthy Blooms: Select dahlias that are free from blemishes, discoloration, or signs of pest damage. Healthy blooms will retain their color and shape better during the drying process.

2. Opt for Fully Developed Flowers: Look for dahlias that are fully developed with petals fully open. Avoid buds that have not yet bloomed, as they may not dry properly.

3. Select Sturdy Stems: Dahlias with sturdy, thick stems are ideal for drying, as they will hold their shape better during the drying process and make handling easier.

4. Consider Color and Variety: Choose dahlias in a variety of colors and shapes to add visual interest to your dried arrangements. Experiment with different varieties to create unique combinations.

By carefully selecting dahlias that meet these criteria, you can ensure the best results when drying and preserving them for future use.

Methods of Drying Dahlias

There are several methods for drying dahlias, each offering its own advantages in terms of convenience and preservation quality. Here are some popular methods to consider:

1. Air Drying: Air drying is one of the simplest and most traditional methods of drying flowers, including dahlias. To air dry dahlias, gather several stems together and tie them with a piece of twine or string. Hang the bundled stems upside down in a well-ventilated area away from direct sunlight. Allow the dahlias to dry completely, which can take one to two weeks depending on environmental conditions.

2. Silica Gel Drying: Silica gel is a desiccant that absorbs moisture from flowers, making it an effective method for drying dahlias while preserving their color and shape. To dry dahlias with silica gel, pour a layer of silica gel into a container with a lid. Trim the stems of the dahlias to your desired length and place them upright in the silica gel, making sure the blooms are not touching. Gently sprinkle additional silica gel over the blooms until they are completely covered. Seal the container with the lid and leave it undisturbed for several days until the dahlias are fully dried.

3. Pressing: Pressing is a classic method of drying flowers that works well for dahlias, especially smaller blooms. To press dahlias, place them between two sheets of absorbent paper, such as blotting paper or newspaper. Arrange the dahlias in a single layer, making sure they are not overlapping. Place heavy objects, such as books or bricks, on top of the paper to apply pressure to the dahlias. Leave the dahlias pressed for one to two weeks, replacing the paper if it becomes damp.

4. Microwave Drying: Microwave drying is a quick and efficient method for drying dahlias, though it requires careful monitoring to prevent overheating. To microwave dry dahlias, place them between two paper towels on a microwave-safe plate. Microwave the dahlias in short intervals of 30 seconds to one minute, checking them after each interval for signs of dryness. Be careful not to overheat the dahlias, as this can cause them to become brittle.

Choose the drying method that best suits your preferences and resources, keeping in mind the desired outcome in terms of color, shape, and preservation quality.

Post-Drying Preservation Techniques

Once dahlias have been dried using your preferred method, it is essential to preserve them properly to ensure they retain their beauty and longevity. Follow these post-drying preservation techniques to keep your dried dahlias looking their best:

1. Sealing with Clear Spray Sealer: To protect dried dahlias from dust and damage, consider sealing them with a clear spray sealer. Hold the dried dahlias several inches away from the spray sealer and apply a light, even coat over the entire surface of the blooms. Allow the sealer to dry completely before handling or arranging the dried dahlias.

2. Storing in airtight containers: Store dried dahlias in airtight containers, such as glass jars or plastic containers with tight-fitting lids, to protect them from moisture and pests. Place a layer of silica gel or rice at the bottom of the container to absorb any excess moisture. Arrange the dried dahlias in a single layer, taking care not to crush or overlap them. Seal the container tightly and store it in a cool, dry place away from direct sunlight.

3. Avoiding Humidity: Dried dahlias are susceptible to damage from humidity, so it is essential to store them in a dry environment. Avoid displaying dried dahlias in areas of high humidity, such as bathrooms or kitchens, as this can cause them to become limp or moldy. Instead, choose a location with low humidity, such as a living room or bedroom, to showcase your dried arrangements.

4. Regular Maintenance: Periodically check dried dahlias for signs of damage or deterioration, such as fading color or brittle petals. Gently dust the dahlias with a soft brush or cloth to remove any accumulated dust or debris. If necessary, touch up the dahlias with a clear spray sealer to restore their appearance and protect them from further damage.

By following these post-drying preservation techniques, you can prolong the lifespan of your dried dahlias and enjoy their beauty for months or even years to come.


Drying dahlias offers a practical and rewarding way to preserve their beauty and extend their lifespan beyond the growing season. By selecting the perfect blooms, employing the appropriate drying method, and following post-drying preservation techniques, you can create stunning dried arrangements that will enhance your home decor and evoke the splendor of dahlias year-round. Experiment with different drying methods and preservation techniques to discover the best approach for preserving dahlias in your own unique style.
