Questions on anubias and ferns on wood
Please pardon my very rudimentary question, I am new to plants.
In LFS here, anubias and various ferns are sold tied to drift woods with fishing lines. They are placed in a plastic bag tied at the top (but not air tight), with minimal water at the bottom, presumably just to keep the humidity up.
If it matters, we are in the tropic where temperature and humidity is typically high.
1. If I buy those plants and submerge them, would they shed leaves initially?
2. If I submerge the wood/roots/rhizomes in water but leave the leaves sticking out of the water, would the leaves dry up and drop?
3. Which of the above would have more severe die off?
My plan is to do number 2 in the short term, and slowly fill up the tank once the tank becomes conducive for fishes. Any advice would be appreciated.
