Elephant Ear question
In the spring I purchased and planted some elephant ear bulbs in my gardening area. Thanks to some bad information, I planted them in a nice, bright, full sun spot (shame on you Florida-Friendly Database!). Since then, I have learned that for Central Florida they actually prefer partial shade. That said, they do seem to be doing quite well in their spot (I have to do a little extra watering on days when we get no rain [using collected rainwater, of course]) with one exception and I'm not sure if this is natural growth or not.
The outer leaf is constantly yellowing and then dying. I would almost think it was sun-burn, but it is only the outer leaf that is yellowing, the inner shafts and leaves are nice and lush looking. About a week after the outer leaf has died, a new leaf will start rising from the center and the next outer leaf will start to yellow. So there is always at least 3-4 leaves per plant. This cycle makes me think that it is just the way that they grow. But I have seen other elephant ears that have almost double the number of leaves and no yellow ones. The soil they are in is sandy, but it was amended with Black Kow when I planted the bulbs. I know there are a huge number of Elephant Ear varieties, but does this sound like natural growth or nutrient deficiency or too much sun or something else entirely?
Thank you in advance.
