"Concentration? You can only keep it going for so long, so I split my practice into 30-minute sessions. I have a Huxley all-weather green in my garden and I'll spend an hour a day on that. At a tournament you have to adapt to the speed of the greens so I spend more than an hour each day on that.
"Confidence comes from knowing that your technique is good. I use a mirror to check the alignment of the putter blade is correct, that my eyes are over the top of the ball, and that my shoulders are square.
"Then I'll practise long putts of up to 60 feet by putting a tee peg in the ground a putter's length behind the hole and seeing how many balls I can get between the tee peg and the hole. This encourages me to hit the ball hard so that it reaches the hole, but not so hard that it goes too far and I'm left facing a three-putt.
"Good putting is a lot to do with attitude. I know it sounds obvious but you must think you're going to make every putt. If you think you're a great putter then generally you will be. And the reverse is true, too."
Another good tip offered by Dredge is to visualise success.
He explained: "Say it's the last hole and you've got a sixfoot putt to win the tournament and make a lot of money.
"What I try to do in my mind is go through my repertoire of past putts from the same distance that I've holed. Then, as I'm preparing to putt, I visualise the ball going into the hole. Things like that help boost confidence."
Dredge uses an Odyssey 2-Ball putter, which has the white images of two life-size balls mounted in line behind the blade. He said:
"It helps me keep the putter on line when I swing it back and through a stroke.
"It's all a matter of personal preference. My putter works best in a straight line. But Tiger Woods uses a method where he opens the blade on the
way back, comes through to hit the ball square, and then closes the blade in the follow-through.
"If you're an amateur looking to improve, I would suggest a lot of practice and read up on putting. I've read what Tiger Woods does, what Jack Nicklaus did, and I've read instruction books by experts I respect like Dave Pelz.
"Putting is such an important part of the game that it's crucial you spend time perfecting it."
