How do I get last year’s mandevilla to bloom again?

During the winter, we don’t want to feed our mandevilla since the days are so short.  Once summer arrives and they are growing quickly, they’ll need to be fed every 2-3 weeks with a high phosphorus, soluble plant food like Jack’s Blossom Booster (10-30-20).  We also don’t want to keep the plant soggy wet all the time, just lightly moist.  Always check to see if the soil is moist before watering.  Poke your finger a couple of inches into the soil before watering.  if the soil feels damp, wait a couple of days and check again.  It is better to underwater a bit that overwater…plants drown very quickly.
