I need help with my air plant. I do not see an air plant group. This one in the picture has lost many arms. I know to shake plant after watering. I have given it air plant fertilizer, I just put all my plants soaking in water for 20-30 minutes, shake all water off then put upside down on a towel. Should I just spray it and not soak it. This is the only one like this I have. Thanks for your help!!
