I agree with Nooduck. Try to start with plain pre-cooked mielies or fish with white bread, you can also try earthworms.
It would be good if you could feed an area a day or 2 before your fishing session, then fish that area.
If you cannot, then start by using plain mielie bomb feed, cast about 5-7 bombs out to your spot before baiting up (to make a feeding area). I would start with Garlic floaties (I use Vampire small bleeding floats- Magicbaits on a Diachi #1 hooks, 8lbs Maxima Ultragreen hooklinks). Sliding rietvlei trace.
If you want to use dip. Start with very little, then if no bites, put a little more.
Don't give up, when I started I had no clue about freshwater angling, but if you persevere you will catch.
