I am having a hard time constraining my ideas to those solely used for growing fruit, but here is another.
For anyone with a drop ceiling in their basement who has popped up a tile, you might have seen these:
A 50 count of these ~6 foot long drop ceiling hanger wires Is less than $30 at the orange big box home improvement store in my area. Spray them with a degreaser and rinse clean a few times, then spray them with distilled white vinegar a few times and they quiet down to look like this:
Use bolt cutters to shorten them (I like to get four pieces out of one stick, each about 18 inches in length), bend them into a U shape around a bicycle seatpost
and they can be used as large earth staples to hold drip/micro spray irrigation supply lines or soaker hose
remesh cages for protecting fruit trees or as tomato cages (still a fruit)
or if you have a Dymo Rhino M1011 label maker with the integrated hole punch, to anchor your identification tag securely to the ground nearby.
