Yellow leafs are probably the result of over watering. Let the soil become bearly damp before you water it. Also, I the smell is probably normal (remember, legumes have a sybiotic relationship with a species of nitrogen-fixing bacteria).
I plan on repotting the plant into a smaller pot toi conserve space in the next few weeks. I was wondering what the necessary steps would be for taking the plant inside as to avoid shocking it.
To do this, you would take it from its current pot when the soil is just only damp, remove the soil, trim its roots, place it in the smaller pot, and fill it with fresh soil. Do this when the tree is not actively growing.
