Earlier in the season I was looking for fencing to go around the new dwarf cherry trees. The dogs were running through the tree patch and I didn't want them to damage the poor young things. Previous owners of our house left behind lots of these beautiful metal border fences. I tried to find some to match but the high quality ones were cost prohibitive and the cheap ones just looked cheap.
I decided to use sticks from around the yard and make a stockade type border. I chose 12 - 15 inch long sticks and embedded them as deep as I could pushing with my hands. I spaced closely so the dogs would get the idea to stay away from the trees.
Later, I made another fence around the kale bed.
When you are next looking for a free, easy border, think stockade!
