these are getting fairly big now and 2-3 lots of flowers per plant

when do I start to feed them and also can some one explain or link me how to take cuttings

confused about when to take cuttings and what part to replant

All the shoots that grow out of the plant's armpits should be pinched out - you clearly have some to remove in your pics. See step 2 here

These are the shoots that you can use for cuttings - just stick them in some compost
