How To Dry Sunflowers And Keep Them Fresh: 4 Simple Ways

June 3, 2025

Sunflowers are cheerful, bold, and beautifully golden, instantly brightening up any space. But as much as we adore them, their bloom doesn't last forever. If you're hoping to keep that sunny joy going a little longer, you're not alone.

Whether it’s a sunflower bouquet you received on a special day or blooms you picked from your own garden, preserving sunflowers can be a rewarding little project. In this guide, we’ll go through 4 simple, effective methods that show you exactly how to preserve sunflowers, especially if you're looking for the best ways to dry sunflowers.

You don’t need to be a professional or have fancy tools—just a little patience, the right approach, and a bit of creativity.

1. Air Drying Sunflowers The Old-Fashioned Way

Air drying is one of the most common methods—and for good reason. It’s natural, budget-friendly, and works well if you're preserving sunflowers for decorative purposes.

Here’s how to dry sunflowers using air drying:

Remove all leaves from the stem. Leaves retain moisture and can cause mould.
Cut the stems to your desired length, ideally around 15–20cm.
Gather about 3–5 sunflowers into a bunch and tie the stems tightly with twine.
Hang the bunch upside down in a dry, dark, and well-ventilated room. A wardrobe, attic, or unused storage room works well.
Leave them for about two to three weeks.

You’ll know they’re ready when the petals feel papery and the stems are stiff. The vibrant yellow may fade slightly, but they’ll still look lovely and rustic.

2. Using Silica Gel For Vibrant Results

If you’re hoping to preserve the sunflower’s bright colour and delicate petals' shape, silica gel is your best friend. It’s especially useful for preserving sunflowers for display or craft work.

Here’s how to preserve sunflowers using silica gel:

Find an airtight container large enough for your sunflower head.
Place a thin layer of silica gel at the bottom of the container.
Carefully place the sunflower face-up on the gel.
Gently pour more silica gel over and around the petals until fully covered.
Seal the container and leave it for 5–7 days.

When you take the flower out, dust off any excess gel with a soft brush. You’ll be amazed at how well the colour and structure stay intact.

3. Pressing Sunflowers For Flat Keepsakes

Pressed flowers can be turned into bookmarks, cards, or framed artwork. While sunflowers are thicker than daisies or violets, pressing still works well, especially with smaller varieties or just the petals.

Here’s how to dry sunflowers through pressing:

Remove the stem and flatten the sunflower head as much as possible.
Place the bloom between two sheets of absorbent paper (like blotting paper or coffee filters).
Sandwich the paper between heavy books or place it in a flower press.
Leave them for 2–3 weeks.

The result? A thin, dry sunflower you can use in flat-lay art, memory albums, or DIY gifts.

4. Wax Dipping For A Glossy Finish

Wax preservation is a lesser-known but fun method if you want your sunflowers to look fresh and vibrant for longer. It’s more of an art project than a traditional preservation method, but the results are eye-catching.

Steps to preserve sunflowers with wax:

Melt paraffin wax in a pot on low heat. Do not boil.
Once melted, remove from heat and let it cool slightly (you don’t want to burn the flower).
Dip the sunflower head gently into the wax, holding it upside down.
Let the excess wax drip off and place it on wax paper to dry.

The sunflower will have a slight sheen and a preserved, almost “frozen-in-time” look. It works well for short-term decor and craft use.

A Few Tips For Better Preservation

Always handle your sunflowers gently. Once dried, petals can become fragile.
Try to harvest or preserve flowers that are in full bloom, not wilting.
Avoid humidity. It’s the main enemy of dried flowers.
If displaying dried sunflowers, keep them out of direct sunlight to prevent colour fading.

Conclusion About Drying Sunflowers

Preserving sunflowers isn’t just about keeping flowers—it's about holding onto moments, memories, and a little piece of nature. Whether you choose to air dry, press, dip in wax, or use silica gel, each method offers its own charm. Now that you know how to preserve sunflowers, you’re ready to give your beautiful blooms the second life they deserve.
