This is my go-to wire for vertical mounting and situations where I want to hide my work. Wire is 24 gauge plastic coated aluminum and is 180 feet in length so it will last you a while.
To ensure health of plant, apply wire like a seatbelt; loose enough to allow the plant to move a bit and grow but positioned so it will keep the plant secure in case of a strong gust of wind or display being disturbed.
