Hello. I am new to gardening and am not familiar with taking care of plants other than watering. I received an orchid for my mother's funeral about 2 months ago which was beautiful. It has started to shed its bloom, which I thought was normal, but now 3 of the bottom leaves have turned yellow. I must be honest and say that when my sister-in-law was here, she said someone told her to water the orchid with placing ice cubes (just a few) on top of the moss, so they will drop water down as to not over flood the plant (which is what I have done). The plant is indoors near a north window. I live in Miami, so the air conditioner is on all the time, but no direct air vent is near the plant. The rest of the leaves look perky and upright. Any advice would be appreciated. I would love to have this plant for a long time. Every time I see it, I am reminded of my mom who was great with plants. Thank you.
