I am new to bananas and have planted 2 five foot tall Abasinnians in my back yard. I live in north texas and it has been VERY hot. The plants have only been in the ground a couple of weeks and the leaves look dry, brown, and cracked. The leaves that still look good just hang by the stem like a sheet of paper folded over a dowel. I am watering by soaker hose about every 2 to three days for about an hour. Some people have told me its too much water others say too little. it looks like too much sun to me but i dont know what i am doing. Please help
