Sangel welcome to the forum. Try soaking the root ball in water for several hours and then rinse off as much dirt as you can, in order to better see the roots. The roots need to be carefully separated, perhaps a eating fork or a thin screwdriver would help get in between the tangled roots. No matter how careful you are, there will be some wounds to the roots and you may even have to take a knife and slice into the root mass, sacrificing some of the smaller bulblets. Dip the roots in ground cinnamon, which is a natural antiseptic and plant the bulbs at the same depth as the mother bulb. You can plant quite a lot of bulbs in the pot. They like to be crowded. Best of luck, those are very nice amaryllis plants.
