If you use a good soil mix (like FF) you should not need to fertilize for the first 2 or 3 months. All the goodies are there already. If you think you need some ferts in the early vegitative stage use some 14-14-14 time release. It is cheap, will not burn, covers all your plants needs, and you put it on and forget about it.

Good Luck and I hope your ladies turn into huge trees.
