Help ! I got this string of bananas/dolphin. It was doing beautifully , however the day I brought it home it did get a lot of sun in the car. It quickly started drying out. I have maybe watered it 2-3 times since I got it about a month ago. It keeps on drying I looked at the roots today and I am not sure what it needs ?! I don't want to over water it as I am prone to causing root rot a lot.
