Nerifolia and boxwood indoor office setup
I'm new here and to bonsai trees. I purchased lights, humidifiers, and a couple of nerifolia trees and one boxwood with roots over rock. All three against a window facing SW. Temps stay above 72F in the am and can go as high as low 90s in the PM. Lights stay on 14 hrs and humidifier during the day. I water the trees daily and humidity meters show moist to wet.
1) can I or should I use fertilizer?
2) the soil looks a little wet, how often should I water if I have a humidifier?
3) any other tips ?
