Just one thing to add: No problem with whatever colors you choose to use
for yarn, ties, clips, etc, for your own enjoyment. But when you decide to
show a plant (you will, one day!) or participate in a society display, you
want to downplay the staking materials. In our area, and I suspect in
others, a display would lose points for yellow twist ties, for example.
Must be green, and as Kenni mentioned, hidden as well as possible.
