As we’ve discusses before, kratom houseplants love humidity, dappled sun, and plenty of moisture through their well-drained root system. Letting the immediate warmth of the day over-run my understanding of the kratom plant, I chose to place my potted kratom plant on the porch in partial sun earlier this week.
May is too early for prolonged outdoor exposure for kratom houseplants, at least in USDA Zone 5. Although the temperature was in the 80s and the humidity was chokingly high, the average temperature in May is just too cold for the tropical kratom plant. I set about writing inside and forgot that I had moved my plant until I went to mist it several hours later. I remembered how humid it was outside and promptly decided to leave it be, as it was still early afternoon, and the sun was warm even with all the cloud cover. I got back to work, and didn’t even notice when it started raining.
After a crack of thunder, I realized it was likely too windy outside for my still-establishing kratom plant. Thankfully, it wasn’t getting much wind exposure. What it did have was some moderate leaf drop. Once I stepped out from under the awning to pick it up, I understood why; the rain was freezing cold.
Although it was warm and humid on the surface, way up in the clouds it was still nearly freezing. That cold rain had killed off some of the weaker, already damaged leaves. I rushed it inside and set it back in its warm little haven by the south-facing window.
The next day, it was looking nicer (less raggedy leaves), if a bit sparse. And then I saw this dude chilling on my plant:
Between the leaf drop and the weird almost-cricket, I’m disinclined to take my kratom plant outside again until it’s very, very warm.
