I agree. Don't stake it. Not really good for trees. Of course I don't know what a Wahoo is. (I'm at war with Yahoo but that's different.) When you mulch it, don't let the mulch get right up against the Wahoo. Leave a little breathing room. If you can get it, shredded native (native to where you live) bark is usually the best mulch.
And when you do water it, make sure you water under or just a little past the drip line. Soaker hoses are great for that.
Yes, do send a picture or I will have visions of Yahoo running thru my head!
Good luck.
