1. Don't take full swing wedge shots.
2. Club up.
3. Choke up.
4 Weight 70% on the lead leg.
5. Don't try to hit the ball.
6. Rotate chest and fire that hip!

I was in that boat not long ago. You have a few options to play with.
Open the face just a touch to use the wedge bounce more.
Play the ball up more like a 7 iron and be sweepy with it.
Look at wedge grinds or a wedge fitting. You might be shocked to find that the pros are playing with much more forgiveness than you.

Hi,
First, Watch your ball position, it should be centered in your stance.
Plexus solar over the ball ,
Second, your hand in line with the ball.
Third, Start your backswing with your torso (chest) not your hands.
You have to rotate back and rotate through the ball.
Four, Complete your swing.
Dont try to overs wing, let the club do the job.
You should accelerate so do not start to fast because you will decelerate.

Honestly, I submitted some tips previously, but I forgot to tell you that the fastest way to improve is to see a pro. Tips weekend golfers gave are things that are working for them but no guarantee they will work with a particular swing.
Have a nice season,

Couldn’t agree more. The prior posting (5 steps);all are geared to better weight transfer. Number 1 reason for fat shots is having too much weight balanced on the rear leg. The reason you are there is best solved with a pro in 2-3 lessons.
Or you can do what I tried for years. Find the solution myself. Turns out I had a better chance of finding a unicorn.

As soon as I figure it out, I'll let you know.

Go see a teaching pro and let them work with you.

We played Monday with a young man who had the same issues. He could hit the ball a very long way. No control on the tee, but his drives were in the 300 plus range, but in another zip code. Short game, well, really felt sorry for him. He either chunked them or hit them another mile (not really), but no control whatever. On our hole #15, par five, his drive was 90 yards from the pin. His his wedge at least 125 yards, which went over the green into the swamps. His third shot coming back, same result. Ended up taking up a 7 on the hole. His second drive to the fairway all day. His first one was on number one and we thought boy this kid has got game, until we saw his short game and his made a snowman on the par four. Nice drives. A teaching pro could really help him and make him a single digit. He has great potential. Better than average putter.

One thing that always helps me when i start fatting wedges is moving it back in my stance.
I also take a page from Jordan Spieths warm up and take practice swings just sweeping the ground just enough to find the bottom of my swing.
usually does the trick!

Slow down, and try quarter and half swing

Without seeing your swing it's really hard to give solid advice...and thats why a lot of people will tell you to see an instructor. That being said, I would have you go through a short checklist of things. First, stance: for a wedge make sure you have a narrow stance. I see far too many golfers look like they are setting up for a driver with a wedge in their hands. Second, ball position: put the ball in the center to one ball back of center of your stance while your weight is distributed 50/50...then put your weight to 60/40 favoring your lead side. This will allow your sternum to be ahead of the ball at set-up. Third, left shoulder down: you should feel like your left shoulder is low, not raised higher than your right shoulder. When you feel its lower than your right shoulder it's probably just about level. Fourth, backswing: keep your weight forward, don't try shifting 100% to the trail foot. You're probably going to want to feel that it stays on your left foot or at the vary most goes back to 50/50 in the backswing. Fifth and final check, downswing/hands: make sure you don't feel like you are throwing the shaft with the fingers of the right hand. Your right hand should feel like it is pressing into the grip with the heal pad of the right hand. This will help you feel that the back of your left hand is coming down into the ball which allows the clubhead to lag high and behind the hands giving you a decending ball-first blow. Bonus sixth checkpoint, rotation: golf is a rotational sport. Make sure you keep the hips and shoulders rotating around the spine throughout the shot.

You may not need to do all of these things but they all will promote a ball-first impact position. An instructor would help you see which may help you best. Hope something in this helps.
