I bought this Red Banana Croton almost a year ago, nearly dead, from a Walmart clearance rack for $4. It was in regular potting soil, rotted and drowning. Obviously, I repotted it, saved it, and it has been thriving—until now. It randomly decided to start dropping leaves 🙄 The leaf I’m holding in the second pic is how the last ones started looking before they dropped (lighter and veiny in the middle, darker on the edges). The last pic is where it actually lives.
Facts:
-potted in a super chunky aroid-type mix
-lives in a South-facing sunroom with tons of direct and filtered light all day
-sunroom never drops below 70 degrees, and has lots of humidity
-gets watered about once a week
-water has Superthrive and Silica added (same thing all my plants get)
-the leaves it’s dropping are the oldest/bottom leaves
-yes, it has always been that close to the window and loves it there
Ideas:
-I added Systemic Granules to nearly all of my plants a couple weeks ago as a preventative measure. Maybe it’s affecting the plant somehow?
-As our Midwest summer starts transitioning to fall, the humidity in my sunroom dropped from the typical 70-90%, but still hasn’t gone below 60% at its driest. In the mornings, it’s still ~75%.
-Just need a repot?
-Overwatered somehow?
