My usual practice routine is 4 arrows from about 16ft up an extension ladder, at targets at various distance.  Then climb down and shoot at a buck target that is 35 yards from the tree.  I find I tend to shoot better from the tree and low from the ground. Which if I sot perfect from the ground would make me high from the stand.  It is the geometry of the angle.  Practice practice practice.

Sometimes shooting high ground or tree is not picking a spot.Our brain will automatically focus on the horizontal line of the back (b/c of the contrast)and send the arrow there.Right over or spine hit.My .02 Kip

To be honest. I have never noticed a difference(even with the wheels) nor do I aim low when I am 20ft up or more.Maybe it's just me.But friends of mine do have these issues.Maybe because I always practice from my stand in the yard.But when I am on the ground I shoot the same.  

All you can do is practice. I shoot a few arrows before I climb down every morning.

Remember this...Nobody misses LOW from a treestand.

Have you just noticed that you have troubles shooting from a tree stand?  This should have been discovered and taken care of long before hunting season. If you know you can't shoot from a tree stand please don't hunt from a tree stand.
 In many cases, if the archer is shooting over the aminals back and he shoots instinctively, he is not picking a spot and 99% of the time the arrow will fly over the target.

Also remember when bending from the waist keep your back elbow up forming a straight line in relation with your shoulders and bow arm.

Your arrow simply went where it was pointing!    shoot your bow like a shotgun and it will take care of itself

What I do is pick a spot on the under side of the deer and I haven't shot high or over the back in the past few years. When I miss I miss big doing something stupid like dropping my arm or snap shooting. Lol. hope that helps ya some

You might try drawing your bow level, then bend at the waist until you are on target. As Hitman said, everything needs to be inline. The deer here in Texas are really wired, you cannot shoot too low. At times I have had to actually aim around their knees to hit one.  Alot of people that think they shot high, really didn't, the deer just ducked your arrow.  Even on the bigger Kansas deer I hunt I always aim very low.  R.W.

Why do traditional hunters hunt from a tree stand anyway?
Get on the ground..puts you on  a level playing field with the animal you are hunting.Thats just my way of looking at traditional hunting.  

All this good advise....  Shoot for the bottom 1/4 of the chest then aim a little lower if they are far enough to duck the arrow.

The reason you hit high by the way is the shot looks farther than it is.  You want to shoot for the horizontal distance from bottom of the tree to the target-not the straight line distance from treestand to target.  The straightline distance if farther, hence you shoot higher than necessary.

Hunting on the ground is a though  business its not for everyone.

at 20 yards that deer  has no chance of ducking a arrow coming from my widow. You have got to be shooting some inferior shi! moving at molasses speeds for a deer to duck your arrow. Unless your making a 30 or 40 yard shot which not many of us do. Hey that's my opinion though

I've seen deer duck arrows from 300fps+ wheelie bows at 20yds.

Little sarcasm,
I haven't seen it in my 15 years with a stick bow. 15-20 yard max for me though

I have this thing about focusing on the heart....as 99.9% of my misses in my bowhunting career have been high and I've never wounded a deer by shooting low.
Early on I used to focus on the middle of the chest and had my share of over the top or backstrap hits...

That's the way I did it in the mid 60s and it was tradional enough for me and my friends.   I'll shoot them anyway that is legal and gives me the best advantage over them for that location.

+... I always first look at angle of shot.. I do a pretend shot in my mind. Closer the deer to stand you need to shot higher through chest anyway for the right angle through vitals. If you can ever get one of the bowhunter safety course 3-d deer models it will show you a bunch for shot angle.. JUST PARCTICE TOO

Don't think just Shoot!!!!!!!!!
