Time passed is a poor method to determine WHEN to transplant. To see if cutting has rooted GENTLY pull the cutting IF resistance is felt then rooting HAS started.... To tell when to transplant to a larger container gently "pop" the cutting & soil from the container & IF the ROOTS have reached the outside of the soil ball then its time to transplant.... The same method works each occasion it is necessary to move to a larger container ie. from 4" to pint to Qt to Gal to ......

Then comes the fun part of separating the little ones. Best method I have found is to tip the whole thing out of the small pot into your hand and submerge in water to tease those roots apart. When you are more confidant, you will do one cutting per pot, or plan to just snip one off if both take. Fun, isn't it?
