Q.Cally lily turned yellow, burnt edges
I bought a cally lily plant in April which had 2 blooming flowers then. It was placed indoors and I watered alternative days or less with very little water. In June one flower started to look dry, then it died. Following that one leaf turned yellow and I trimmed it away after reading that it may be too wet, so I re-potted it, trimmed away the bad wet leaf, reduced my watering and placed in outside (partial sun at certain hours). That didn’t help either; more leaves are turning yellow. One leaf appeared eaten away or burnt edge. What is wrong? Can I still save it?
This could be a nutrient issue.
Have you fertilized?
Also if the roots were in soggy soil it is possible they plant suffered root rot.
