To preserve plants for year-round enjoyment, use glycerin to remove moisture and keep plants in their original shape. Glycerin prevents plants from wilting and dying, and allows you to display your greenery in your home without constantly worrying about watering or feeding.
Although glycerin preserves the texture and shape of plants, it will cause them to change colors. Certain plants react better with glycerin than others, so you will need to experiment to determine if it is the right preservation method for you.
Pick the plants you wish to preserve. Remove damaged leaves from the plant.
Cut the stems at a 45-degree angle. Cut woody stems about an inch up the stem to split them. This helps condition the plant for the glycerin by allowing the plants to drink the solution.
Soak the plants in warm water. Allow them to drink the water overnight.
Prepare the glycerin solution. Mix one cup of glycerin with 2 cups of boiling water. Mix the ingredients until blended well. Pour 3 inches of the glycerin solution in a vase tall enough to hold the plants.
Allow the solution to cool. Once it reaches room temperature, remove the plants and place them into the glycerin. Place the container in a cool, dark environment.
Check on the plant daily. Once the brown glycerin solution reaches the top of the leaves the flowers are finished. You will notice that the leaves and veins change to a completely different color.
The time it takes for the plants to preserve depends on the type of plants.
