bellsfryWhat's wrong with my pineapple plant?
artifexI have dozens of pineapples in my (very sandy) south Florida soil and this looks like a drainage problem to me. Either the roots are having too much trouble growing into the soil, or there’s too much water.
With a single plant it’s hard to know. I would cut the watering back to once a week without any additives. Give it a real soaking and let it drain and go dry over the week. Also, as soon as they little pineapple starts to turn yellow at the bottom (or when it smells like pineapple) cut it. It’s not going to get bigger than that, and that will tell the plant to put its energy into roots or a new stalk (pineapples are bromeliads , so they self-propagate). Good luck!
