Adjust oven racks so that one is in the center and another below it. Place a large baking sheet or two on the bottom rack to catch any possible drips.
Preheat oven to 200.
Slice your citrus fruits into ⅛” slices and spread out on your oven rack, in the center of the oven so that they are directly over the baking sheets.
Bake for 2 to 2 ½ hours turning at least once until they are completely dry, watch the last half hour carefully so that they do not burn, smaller citrus like lemon and lime will be done quicker than larger orange slices.
Remove from oven and cool.
Gather all the items you might want to use for your wreath.
Before you glue everything down play around with the items you have chosen to use and arrange them on the wreath. Long pieces of greenery should be put into place first and any other long stems you have, including fresh or dried herbs.
Then add layers of citrus.
Tuck in some additional items like berries, pinecones, or cinnamon sticks.
If your wreath does not smell as strong as you like you can add a couple of drops of your favorite holiday essential oils to the back and refresh as needed. Citrus, eucalyptus, cinnamon, pine bark, and clove all make lovely holiday scents.
My trick to keep my wreaths out longer is to make the items I add such as the citrus and greenery fairly neutral and non-seasonal. I used eucalyptus which adds green without using evergreen pieces. You can also use fresh or dried herbs as well.
Add your bow to the top with floral wire instead of hot glue so that it is easy to remove and change, Then early in the season you can add a fall ribbon, and after Christmas swap it out for a wintery one like a bright blue with snowflakes, Finally I also attached the red berries with floral wire so they are easy to slip in and out with a few snips.
