Want to use them to support very old pear tree that has pears that could very well fall down in a storm. If you have something, let me know. Photos show the tree and the last of its pears. Cuttings of this tree will be available later in the season. It is a hardy tree that has stood over 60 years and has born a lot of very delicious pears. The arrow shows where I want to support the tree.
