NIGHT-BLOOMING CEREUS DO WELL AS INDOOR POTTED PLANTS, THOUGH KEEP IN MIND THAT THEY CAN GROW TO BE 10 FEET TALL.          BE SURE TO USE AT LEAST A 10-INCH POT BUT DON'T WORRY ABOUT REPOTTING BECAUSE YOU'LL SEE BETTER BLOOMS IN ROOT-BOUND POTS.       HOWEVER, UNLIKE THOSE PLANTED IN THE GROUND, POTTED NIGHT-BLOOMING CEREUS COULD TAKE FROM THREE TO FIVE YEARS TO PRODUCE FLOWERS.        DURING THE SUMMER IT'S BEST TO PLACE POTTED PLANTS OUTSIDE TO ENJOY A LITTLE SUNSHINE.        TREAT YOURS AS YOU WOULD A YOUNG, UNESTABLISHED PLANT AND PLACE IT SOMEWHERE SHELTERED THAT WILL PROVIDE FILTERED LIGHT.        BECAUSE OF THE COLD SENSITIVITY OF NIGHT-BLOOMING CEREUS, BRING YOUR POTTED PLANT INSIDE WHENEVER THERE IS A COLD SNAP.       I MAIL OUT MY PLANTS MONDAY THROUGH WEDNESDAY.
