Hi. I'm an hour south of you in Sarasota. How big are the pots you have these in? I have found them difficult to grow in anything but full sun. Anything less than 7-10 hours of direct sun will make them leggy and susceptable to fungus and insect problems.
Another tip off was buying them at a gift shop. If they were started from
seed they will be hard to manage plus it will take 7 years under ideal conditions to get any fruit.
Citrus can be grown in containers but the care is a little more intense than one
growing out in the yard. Check out the Hillsborough or Pinellas Extention Office website. They will have some good info on citrus care.
If it turns out you do have
seedlings, you might want to consider picking up a grafted
plant from a local nursery. You can tell if your
plants are grafted. There will be a bump or knot near the base where the
plant was grafted on to root stock.
Sorry for being long winded. Hope this helps a little.
