not too long ago when i first looked into figs, there were some talk about "feeding the tree from the bottom". i think this and other forum had picture of people watering the cuttings by adding water at the base.
some are using self watering container which basically does the same thing.
i'm not sure how much benefit there will be for bottom feeding, but the examples that show indicate nice growth.
for the rooting of the cuttings, i rarely water the cuttings until they are ready to go into 1 gal container. in bag and cup stage, i just leave them alone after the initial watering in "rooting chamber". once they are in 1 gal pot, i'll water them maybe once a week. too much watering can rot the roots. i tend to let the water dry out just a bit before giving them further water.
