Hello all. I am distressed. I love Caladiums! I have some in my yard that I dug up from a creek and they come back every year. There was no species ID but I will post a picture below. I have been watering once a week, but the soil seems dry when checking in between. I am terrified of overwatering bc I have lost plants this way. I think the pot may be too small for the plant. It is 4" tall and 6" across. It is in a very spongy soil mix which seems to dry out quickly. It is in indirect sun.
Now the leaves are drying out and dying, one by one. Please help.
