I guess its normal for beginners and more practice will help. It did for me anyway.
When I learnt, my instructor told me when I was turning to think Bank Angle-Back Pressure-Ball, and repeat this while the aircraft was turning so I could monitor the ball (glancing in and checking once every ten seconds, looking out the rest of the time).
If you are climbing or descending you will need rudder one way or the other.
The other main use is when you are turning, e.g. if you move the ailerons, you should move the rudder at the same time, but when you are at the correct bank angle, you come off the ailerons and also come off the rudder as a rule, just making very minor adjustments as part of the Bank Angle-Back Pressure-Ball routine.
So to start with, try to practice moving the rudder every time you move the ailerons, even if only making a minor correction to heading.
Finally, just as I was told I shouldn't be flying more than 30 degrees angle of bank at low level in the circuit, neither should you be using the rudder on its own, or cross controlling (right aileron, left rudder for example). Giving the rudder a big kick on its own at low speed is the recommended way to get into a spin, not something you want to do at low level. So while you shouldn't be scared of it, do respect the rudder and try to fly in balance at all times, particularly when at low level / low speeds.
I would like to add I'm not a flying instructor, I'm only trying to give you some helpful hints here. Hope this helps.
