I would appreciate any tip on how to keep my baby alive and kicking.

I can’t speak from personal experience but only similar experience as I do not own a TC. I have pothos njoy/pearls and jade that do the same thing. This is due to the variegation. The cream/white color you see on your leaf is not able to absorb light as well because it doesn’t have much chlorophyll in it like the darker green portions do. Since you checked roots (and is also recommended checking for pests) i believe this to be the reason behind the browning. I don’t know if much solutions but I feel like i’ve heard of watering with silica can be a good way to keep the white portions from doing that. If someone else could confirm that it’d be much appreciated. #### Zei님이 2024-08-06에 답변했습니다. Thanks for your input David. Your explanation makes sense and I will try your suggestion. I appreciate your help. #### c.cat님이 2024-08-06에 답변했습니다. yes, you are correct, variegated parts of plants cant photosynthesize and are very sensitive to their care and environment. silica water will help prevent browning, but it wont reverse the already brown parts. if you want you can trim it off to keep it looking healthier! good luck! ![1개 중 1번째 첨부 파일](https://images.getplanta.com/v1/resize/kD4THHB2xcLqDKRuHBa3MmDYxLorWKP7RRswqL0yZyo/zAdCyZnPRUSIVvjttcDpeQ.webp?size=large) #### Zei님이 2024-08-06에 답변했습니다. Thank so much! I will do what I can to keep this beauty alive. I will try silica water. Is Neem oil beneficial for variegated plants? I spray mine once in a while. I’m not sure if that’s what caused the issue. #### c.cat님이 2024-08-06에 답변했습니다. i dont think thats what caused it, as its typically used as a natural pesticide on most plants. it most likely turned brown because that part of the leaf is completely white, and cannot keep itself alive for very long. this is why people will cut all white leaves off of other variagted plants, as the all white leaf is draining nutrients and energy. :) #### Zei님이 2024-08-07에 답변했습니다.
