Why do I need to preserve acorns?

Preserving acorns may seem like an extra step in crafting, but it’s necessary if you want to achieve the best results for your Fall decorations and crafts. By preserving acorns, you are not only ensuring their longevity but also enhancing their natural beauty.

Preserving these acorns allows you to capture nature’s beauty at its peak. As the leaves change color (green and brown in Texas) and the air turns crisp, acorns become the symbol of Fall. By preserving them, you are able to extend their lifespan and incorporate their charm into your crafts, centerpieces, or even wreaths. Whether you use acorns as a focal point or simply as a subtle accent, their preserved form adds a touch of warmth and Fall charm to your creations.

Preserved acorns also serve as visual elements while bringing a tactile experience to your Fall decorating. Doing this allows you to retain their natural texture and fully appreciate their beauty.

An acorn’s smooth yet slightly bumpy surface can evoke a sense of longing and connection to the outdoors. I remember picking them up under the huge oak tree at my grandparent’s home during the Fall season when we visited.

In addition to their aesthetic appeal, preserving acorns also helps prevent decay and insect infestation. Acorns are organic materials, prone to rotting if not properly preserved. Preserving them ensures they maintain their shape, color, and durability throughout the season and even years if stored properly. This adds longevity to your crafts and saves you the disappointment of seeing your creations deteriorate quickly.

Now that you understand the importance of preserving these little, earthy nuggets, it’s time to get your supplies together. With just a few simple items, you’ll have everything you need to preserve acorns for your Fall decorating and crafts.


First and foremost, you’ll need a collection of fresh acorns. Look for acorns that are free from cracks, holes, or signs of decay. It is best to gather them directly from the ground as they fall from the trees rather than picking them from the branches. But, if you time it just right, you can pick them from the branches (fully developed) before they hit the ground, which is what I did. The acorns should still have some green color to them.

STEP 1: Choosing The Best Acorns For Preserving

You’ll need a container or bucket to hold your acorns while you gather them up. Look for something sturdy and easy to clean, as the acorns can release dirt and debris while collecting them.

First, ensure that the acorns you gather are in good condition and free from any cracks or damage. Picking them directly from the tree or ground shortly after falling is best.

Are these acorns not GORGEOUS? These are from my red oak tree.

STEP 2: How To Clean Acorns

Next, thoroughly clean the acorns to remove any dirt, debris, or insects that may be hiding. Fill a bowl with warm water and add a few drops of dish soap. You can skip the detergent if you pick the acorns directly from the branches. I find they are cleaner than picking them up from the ground.

Place the acorns in the soapy water and use your hands to gently scrub them, paying special attention to the caps and crevices. Rinse them under running water and pat them dry with a clean towel. Do not allow them to soak for a long period of time, as they will absorb too much water. We’re not trying to drown them, just knocking off the dirt.

STEP 3: Drying Acorns Thoroughly After Washing

Once the acorns are clean, it’s time to prepare them for drying. Lay them out on a paper towel to absorb any excess water.

Then, place them in a single layer on a baking sheet or tray so that they are evenly spaced and not touching each other. This will allow for proper air circulation and prevent the acorns from sticking together during drying time.

Find a dry, well-ventilated area where you can leave the acorns undisturbed until they are dry. About 24 hours or overnight. This can be done indoors or outdoors, as long as it’s a space that remains relatively cool and dry.

STEP 4: Baking The Acorns To Kill Bugs

The next step is very important, especially if you don’t want insects crawling around inside your home.

Worms and other bugs are commonly found on and even inside the acorns. You may even see a tiny hole in the acorn itself. That’s why I recommend that you bake them, especially if you are using them inside your home.

This process not only kills bugs but also dries them out.

Bake the acorns at 175-200 degrees Fahrenheit for 2-3 hours on a cookie sheet. Check them often to ensure that they don’t burn. I like the flip mine over a few times for even baking. The green acorns will turn a beautiful matte brown as they cook.

Next, remove them from the oven and allow them to cool overnight, open to the air. If you notice that a few of the caps are loose or have fallen off the acorn during the cooking time, you can use wood glue or hot glue to reattach the caps after they have cooled completely.

STEP 5: Sealing The Acorns

Look how gorgeous these little gems are! Use them as is, or add a level of warmth by spraying them with a protective top coat.

I sprayed these with an oil-based polyurethane to keep them looking natural and to add a rich semi-gloss finish. You can use water-based or oil. This is what I had on hand.

The urethane spray turns the matte brown into a rich chocolate color. Both are beautiful, but I love the richness of the dark brown.

Once you have successfully preserved your acorns using the methods mentioned earlier, you will have a delightful array of nature’s treasures to enhance your Fall decorating projects. These preserved acorns can be utilized in various ways to add a rustic and cozy touch to your home during the Autumn/Fall season.

One simple way to incorporate these preserved acorns into your Fall decor is by arranging them in a decorative bowl, vase, or container. Fill a clear glass container with your preserved acorns, allowing their natural beauty to take center stage. You can use different sizes and colors of acorns to create an eye-catching display that will instantly bring a touch of nature indoors.

I haven’t attempted to paint acorns yet, but I can foresee it in the near future.

Thank you for joining me today while I share this fun, creative way to preserve acorns.

I’m curious to know how you would display them. Let me know in the comment section below, or say hi so I’ll know you stepped by.

In the words of Ralph Waldo Emerson, “The creation of a thousand forests is in one acorn.”

Happy Fall, Y’all!

Until the next project… xo, Do



  1. Super cute! I can’t believe how great they look once you sprayed with the Varathane topcoat! XOXO

  2. Fantastic idea. How I wish I had an Oak tree now. At least I know where to vacation next time. I’m on the hunt, Thanks. They’re just darling.

  3. I have a small box of fake ones. This year the tree next to a restaurant was dropping them like crazy so I got a tinfoil takeout pan & gathered them. They’re on the smaller scale & all the tops bounced off once they hit the ground. I read a similar preserving procedure on a different website. Stupidly, that website owner said that the ones on the ground were left by the squirrels. (How about no squirrels to be found????) Anyway, I need to reattach the tops with hot glue before I spray seal. Tomorrow I will try a different location that usually yields large specimens. I’m not sure if the weather played a roll in the size or if they are different oak tree varieties.

    1. Hi Robin,
      Acorns fall when they quit growing. I guess a squirrel could drop a few. πŸ˜‚ Oak trees will produce large amounts of acorns every few years. It has to do with reproduction and feeding the animals. It’s extremely interesting to research. Good luck with your hunt. πŸ™‚
