Suzi, I don't remember exactly how many weeks, but past year De la Reina MP took around 12 weeks for rooting. From there on, it rooted well, although slowly.
I have now some cuttings of Albacor Comuna, 8 weeks and no roots yet. From this batch, De la Senyora Sineuera rooted in 2 weeks.
What is strange is that all your cuttings take so long, have you checked temperature?
Below 20º C (68º F), fig cuttings root slowly, on the contrary, in 24º C (75º F) they root faster.
