for now keep them watered -
consider finding pots twice the size to prevent wind blow-over -
I have 2 figs in the ground - both are over 30 feet wide and over 25 feet tall - they grow about 6 feet a year ....
in the summer months, figs benefit from an extra thick leaf mulch extending out to the "drip line" ....this keeps their roots cool in the summer ... but also provides an insulating layer during freezes -
at first freeze, the leaves fall off - and start a winter long dormancy
dormancy breaks when green buds are visible -
prune in the spring, to shape ..
you can start new figs with each branch removed - have several buckets of sand with holes drilled in bottom - stick branch into sand - keep moist but not dripping wet .....in a few weeks there should be roots - repot into a top soil rich, lots of mulch, fast draining media
