Hi Dimi has given you some great advice , if I may add to it, when taking the Basel shoots, you may find that its attached to the lower main stem near the root ball, or around that area , they can but further up the main stem too,from stem nodules , but your is from the lower part and you probably will find that it has no root system at all, when you pull the plant out of your potting mix very gently or you may rip off the Basel shoot , dig around the area to clear it so it dont get damaged , , you can take this Basel shoot off in many ways, best is to use a scalpel ,or new box cutter blade of some sort, wash the blades with a 10% solution of beach and water , best distilled water ,but not 100% necessary , to get a clean blade, wash off all potting mix from the area you going to work on good clean water , cut the Basel shoot off with some main stem on it just a bit , make the cut down wards not up wards , then you will have more control of the cut, take it slow ,dont rush it or the cut will take to much out ok !!,, then treat it as a cutting, you can see how to do cuttings on a vid I did on you tube

is made for stem cuttings but you will get the idea , just treat the Basel the same , it will grow better as it new growth and young , they grow very quickly and strike roots easy too
