I am using the baggie method and I checked on the cutting by un-wrapping the moist paper and noticed a nice light green leaf opening whereas the initials are just a bit bigger than goose pimples. I thought of a number of choices such as (1) Place in Perlite-Vermiculite mixture as usual but remove the leaf to avoid it using nutrients from the cutting and; or (2) Place in Perlite-Vermiculite mixture as usual but place it in better light conditions so the leaf provides energy rather than using it from the cutting; or (3) Place in Perlite-Vermiculite mixture as usual and leave it in warm humid condition with little or no light until rooting.

 What is a better solution for successful rooting of a cutting too eager to leaf out early.

And yes, welcome Adriano.

If you keep the humidity high, and put it in a perlite/vermiculate mix, it will root. The critical issue is maintaining moisture, when you have a large amount of surface area of the leaf evaporating moisture out of the cutting.

What you are seeing is the reason I use clear cups. You have leaves and no roots. Other cuttings will have roots and no leaves, and anything in between.
Leaves and roots are not correlated.

Will it help or jeopardize the rooting process if I cut the early leaf?
Isn't it an extra burden on the cutting at this time?
