|Hello. Since my dad's very unexpected death in June, I have been doing my best to care for his beloved plants. Among them is a potted rosemary plant that is about two feet high. I live in Pennsylvania, and due to the colder weather, we moved the rosemary plant inside to the basement where my dad kept his indoor potted plants. In the last week or so, I've noticed the rosemary plant has started to turn brown. I water it about once a week. There are four windows (about 2 ft. x 3 ft placed high up on the walls) in the basement and the rosemary sits on the floor below the counters where the potted plants sit under flourescent lights that still come on thanks to the timer my father had set before his untimely death. The temperature is around 60 degrees down there, it never gets too warm or cold. So what's the deal? Am I doing something wrong? I put some plant food spikes in it on Sunday, and I don't see much of a difference, and I am afraid to overwater it. Any help would be appreciated. Watching one of my Dad's plants die is like watching another part of him die, so I want to save this precious plant. Any helpful advice would be welcome. Thanks.
