They showed up a while ago but have continued to get worse. I keep the plant in the window and I only water it when the top 1-2 inches of the soil is dry. The spots are mostly only on the backs of the leaves which I find really strange. 🤷🪴 ![3件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/AC8bqta1z7g98CscT91G7nJRIZaIfWrg_3b48TQ5J24/E2N3XgMbQeKXg9qSt2CPjQ.webp?size=large) ![3件中2件目の添付ファイル](https://images.getplanta.com/v1/resize/AC8bqta1z7g98CscT91G7nJRIZaIfWrg_3b48TQ5J24/JzPH_r5wTjiuOzfbOo1ydQ.webp?size=large) ![3件中3件目の添付ファイル](https://images.getplanta.com/v1/resize/AC8bqta1z7g98CscT91G7nJRIZaIfWrg_3b48TQ5J24/nDj0yHg_QC2jYpkp-4HJmQ.webp?size=large) ## 10件のコメント ### Alyssaさんが2024-06-28にコメントしました Looks like pest damage to me, most pests like to hide out under leaves ### Adrianさんが2024-06-29にコメントしました It could be an early sign of edema. I had a similar issue with my raindrop Peperomia that arrived in the mail in a very small 2in pot, so the roots tried absorbing more water than it could given how little soil separated the water from the roots. It’s not very easy to tell by the roots, but essentially the plant’s cells burst from too much water can start to form spots that turn brown and corky. If you start to see “bumps” on your leaves, or curling leaves, that can confirm it. I’ll attach a photo of what mine looked like to help confirm. Hope this helps! #### Adrianさんが2024-06-29に返信しました Edema can happen if the soil is moist while the air is cool, as well as what I stated with what happened with my plant. In mild cases it’s treatable, but important to catch early, as more severe case aren’t reversible. #### Adrianさんが2024-06-29に返信しました ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/CQyscbeN5f0KZltdaSyx3VQZZh8uHYoaKDmCZlFICjE/fs-DPlW3RyahWiL6jlE1NA.webp?size=large) #### Adrianさんが2024-06-29に返信しました ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/CQyscbeN5f0KZltdaSyx3VQZZh8uHYoaKDmCZlFICjE/LGPUamtzTgi7ZI9rpZBZuQ.webp?size=large) #### Adrianさんが2024-06-29に返信しました Another possibility is root rot. I had one issue with my Watermelon Peperomia (and as a side note, peperomia are more susceptible to edema and root rot cause of the succulent nature of their leaves), another one that arrived with the watermelon one, but where only one of the stems was affected, and as the plant is epiphytic it seemed to only affect that leaf, and died on its own, to the point that I plucked it out with no effort completely to its root. This brown leaf was the affected leaf, and it arrived this way, and as there wasn’t any sign of pests, I chalked it up to edema or a root issue, soaked the roots with peroxide and water for 30 minutes and trimmed any rot, and repotted it in dry soil and bottom watered it from then on, and it’s been doing great since. ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/CQyscbeN5f0KZltdaSyx3VQZZh8uHYoaKDmCZlFICjE/YubzqniFRE2H2xbwyG5ocg.webp?size=large) #### 🪴❤️Enzo❤️🪴さんが2024-06-29に返信しました Wow you have been so helpful! Thank you so so much! I will dig it up, check for root rot, and see if soaking it in some peroxide will help it. I am newer to the plant world so I really appreciate you educating me on this. Glad yours is doing better now! :D _アプリでさらに3件の返信を見る_ --- _Plantaコミュニティ (https://getplanta.com)。閲覧はどなたでも可能です。投稿、コメント、いいねをするには、Plantaアプリをダウンロードしてください: https://getplanta.com/download_
