Help with Colocasia esculenta (aka taro aka elephant ear)
Whenever I water my colocasia at least one of the leaves gets a bunch of yellow on it like this and then eventually the yellow parts become brown and crispy. Yellow typically indicates overwatering, but every time I've watered no water has come out the pot's drainage hole which I typically use as an indicator that it doesn't need any more water. I also only water it when the leaves are becoming very droopy and the watering does cause them to perk back up. Anyone know why the leaves are becoming so yellow like this?
