Potted plant on vibrating air conditioner

Question

Is it generally ok for a plant’s health if it is placed on top of a wall air conditioning unit? It doesn’t get very hot, but it does vibrate. Weight will reduces this vibration. I am considering placing a small potted palm and/or a lucky bamboo but I don’t want to do harm! I’ve nowhere else in the little alcove for any plants and can’t drill into the wall. Please help!

Answer 1

The main concern here is not so much the vibrating but the draft or cold air come from the A/C itself (provided this will be indoors). This can oftentimes be detrimental to houseplants. If you have a cool-hardy plant, this may not be a big issue. If it's outdoors, then the opposite may occur--too much warm air coming from the unit.
