Gerbera daisy comes in and out of bloom when grown in the garden. However, if grown indoors it will often not rebloom. You don't say where your plant is growing, but if it's indoors you may just want to toss it. Outdoors, be patient and it will come back again. Just be sure to keep these plants slightly moist. In Illinois, these plants are annuals and will not tolerate outdoor conditions after frost hits.
