Hi. Not sure if this is normal. A while back I bought Oriental Lily from my local supermarket because they were beautiful. MY First Lily. They started to bloom 2 days ago but I noticed that my bottom leave are turning yellow is this normal? the pot itself is about 10 inch wide and they planted 3 bulbs. My plan was to separate them after they bloomed but I do not want to loose them before that. They are outside its under neath a small patio roof due to our high temperature in SA at the moment, i am afraid the extreme heat and direct sunlight will damage it
