Resurrecting my poor sword plant

[TheVoldevader]

Alright, so I've had this sword plant for a year now (I don't know if it's amazon - it was listed as 'misc' when I bought it). It used to grow super quickly and I had to trim it every week, but then I decided to turn the tank brakish, which basically murdered the plant. oopsies It's been close to four months now since it's gone back to FW, and the plant is still alive, but it's hardly growing and super small. The leaves are all green, but they feel super tough now. I think maybe there's been a new leaf in the past month, but I'm not sure.

So it's still alive... but I'm trying to restore it to its former glory. Is that possible - and if so, anything I can do to help it out? Or did I murder him (yes, it's a him) :(

Plants don't appreciate salt in their tank altho there are a few known to do OK in brackish tanks. Your sword may be planted too deep and probably needs root tabs. They are iron hogs and need those root tabs.

I've been dosing the tank with liquid iron ferts :) do they work the same way?

From what I've learned here, some plants benefit from liquid ferts - other plants like swords, need ferts going directly to their roots -hence, root tabs.
