Deciduous magnolia trees, such as the Southern magnolia (Magnolia grandiflora) and the Saucer magnolia (Magnolia × soulangeana), lose their leaves in the winter. Evergreen varieties, like the Sweetbay magnolia (Magnolia virginiana), retain their leaves throughout the year.
To preserve hydrangeas with glycerin effectively, mix one part glycerin with two parts water. Cut the hydrangea stems at an angle and place them in the glycerin solution. Leave them in a cool, dark place for 2-3 weeks until the petals have absorbed the glycerin. Display the preserved hydrangeas in a vase away from direct sunlight for long-lasting beauty.

By preserving autumn leaves with glycerin, an organic emollient, you can create a wreath that will last for months without drying out. This method will also work with green spring and summer leaves. The process requires some experimentation; some leaves don't take well to the glycerin. But the ones that do will be beautiful and last long enough to make the effort worthwhile. For best results, always cut branches in the cool of the evening, and never use leaves that have been through a frost.

To preserve plant material using glycerin, mix one part glycerin with two parts water. Submerge the plant stems in this solution, allowing them to absorb it over several days. The glycerin replaces the water in the plant cells, helping to retain its color and flexibility. Once the plant is fully saturated, remove it from the solution and let it dry; it can then be used for decorative purposes.
To preserve palm leaves, start by cleaning them gently with a damp cloth to remove dirt and debris. Next, you can dry them flat in a cool, shaded area to prevent discoloration. For further preservation, consider applying a thin layer of clear acrylic spray or using glycerin mixed with water to keep the leaves flexible and prevent brittleness. Store the dried leaves in a cool, dry place away from direct sunlight to maintain their color and texture.
One creative way to preserve the vibrant colors of fall leaves while coloring them is to press the leaves between two sheets of wax paper and then use a warm iron to melt the wax, sealing in the colors. Another method is to coat the leaves with a mixture of equal parts glycerin and water, which helps to maintain their color and flexibility. Additionally, you can try using a clear acrylic spray to seal in the colors and protect the leaves from fading.
