Mexican bird of paradise - leaves turning yellow
About a month ago I planted a large (15 gallon) Red Mexican Bird of Paradise. It looked great for awhile but now the bottom fronds are all yellow and brittle and the entire plant appears withered and brittle. I was told that it should be watered deeply but infrequently. I watered it when I first planted it with some B-1 they told me to use. It looks like it just needs water but I want to be sure. I watered it about a week ago and then again today. Someone told me to water with MiracleGro but I haven't done that yet. But it does not look like watering it is helping. Can anyone tell me what I should do? Any help would be appreciated. Also should I cut down in the winter?
