Hi, haven't posted in a while. 2 of my citruses made it through the winter and my 3rd one died. Right now I have a ponderosa and a year and a half seed grown navel tree.

My navel has been growing all winter but the ponderosa's been dormant appart from a flush of flowers that's happening right now.
My window gets a solid 6-7 hours of sunlight a day and I fertilize about every 2 weeks.

I would like to have new growth instead of flowers, is there anything more I can do?
