when do I fertilize

Where are you located? This probably wasn't the best time of year to be root pruning and repotting.

You can resume feeding when you see new growth.

What did you re-pot? Conifer, maple?

i repotted a mexican lime, and a couple of figs and i am in san francisco

Fine time of year to re-pot fig. February is the time I usually do mine.

The Mexican lime may sulk a bit, so be sure the mix is consistently moist but not wet for the next couple weeks, and begin fertilizing in two weeks. Also, keep the Lime warm and offer as much sunlight as possible.
