yellow leaves on daylilies
Need some help on my daylilies. The lower leaves are turning yellow on me and I'm not sure what is wrong. I've checked for any visible signs of pests or insects and don't see any. Other than yellowing there are no other signs of something wrong. Would appreciate all the help I can get. The name of the lily is Sombero Way. I hope this is the right forum correct me if its not, this is my first time posting a question and I'm really not good at computers either.
