Do you have dwarf baby tears (hc) or regular baby tear? Dwarf baby tears won't grow without CO2 and regular baby tears are hit and miss sometimes in tanks that I have owned. In order to plant though, you take each little strand of the plant and plant it a little bit away from the others.Also, if I were you I would get a bottle of Seachem Flourish and dose that once in a blue moon for better growth from your ferns, anubias, and swords. DO NOT add any bottom feeders to flourite because of how rough it is. Also, look up fishless cycling because just having some plants in the tank won't cycle it alone you need to add in ammonia in order for the cycle to start. Also, dy start method does not add in beneficial bacteria unless it has an ammonia source. Nitrogen cycle depends on ammonia. I would have a heater to stop major fluctuations in temperture.
