I had to take a little time to make a leaf run before they all fall. There is a place in my town that has a row of ginkgo trees that I supplement my leaves from. As you can see, they are starting to turn yellow and I could just scoop them up in a big bag and bring home to sort. I try and put a mix of sizes in smaller bags and so I have various types of Japanese maple and ginkgo leaves safely squirrelled away for winter.
Over the years I have tried various methods to save the leaves, but freezing has proven to be the best. I just thaw them out for a few minutes and then they are ready to be rolled into my trays.
