Q.Want to transplant outdoor Gerbera to a pot and bring indoors/winter. Lush foliage now, nothing more after initial blooms-not enough
sun. follow indoor directions? applied time-release fertilizer during summer, which I suppose accounts for the lush foliage. But kept in planter with other flowers in shade.

They need full sun to bloom well. That is probably why yours didn't bloom much outside. When mine stop blooming outside, I fertilize again to get them going.
