It just... happens 



Grey Fox said:Nice collection! They have a way of multiplying, dont they? I really like that tall, fat, blue Peruvianus looking one in the 2nd photo. Do you have a favorite?
In the first pic, it is the second cutting from left to right on the back row. The one right next to it to the right, is also a matucana peruvianus, which you can see in the second pic as the cutting that is growing diagonally. Interesting that they both have that blueish tone but they are quite different looking, very different spacing between spines and all.
You've come a long way baby!!kubizm said:If they already have roots, then they can go straight into soil
You could also cut the bigger ones in half and leave to callous over for 3-4 weeks then plant out.
I've cut and successfully rooted a 5cm and 7cm San Pedro cutting
Store bought cacti soil is all I've used,
For 2 of my Pedro's I've even used just regular potting soil with some dolomite mixed through, and it seems to be growing fine.
