The plant's spent flowers are turning brown. That's ok, but parts of the viney plant itself is turning brown. The plant appears to be dying. It's in a hanging basket. I've watered it everyday, fertilized it every couple weeks. Did I water it too much?

Checking the soil by actually dry is the best. Daily water for container plants is a general rule. It may even need twice daily water if the temperatures are above 85 degrees.
