Cool thats interesting, I'm in CanadaI am in Turkey. Middle East. Only the local farmers and farm shops have decent-ish stuff around here. The other ones are too expensive and I can't afford it.
I just flushed my flowers pot a few hours ago. Should I give water again with nutrients?
It would hurt to feed the little duck.
See what's available to you at a decent price.
And we can figure out the best course of action.
In the meantime give her some organic.
Do you have anything to create microbes?
Bokashi, insect frass? Microbe tea?
And your final pot just local top soil?
Stay safe
