What can I do to prevent this? I have googled it before and it told me to add cinnamon to the top soil. I’ve done that but mold still comes back. Any advice helps. Sincerely, So tired of scraping off mold. ## 10개의 댓글 ### EllaBea’s Forest님이 2025-07-18에 댓글을 남겼어요. I haven’t tried this, but heard about it. If you use very dense soil or compost, it’s good outside, but gets moldy inside. Ways to combat this is to monitor if you’re over watering, mix in perlite, and put pebbles under your pot for drainage. ### fuey님이 2025-07-18에 댓글을 남겼어요. There’s a lot of people with this problem and this is my response from another thread: “I use Mollys Aroid Mix and Sol Soils Chunky mix primarily. I will typically add more perlite to it also. Bottom-watering and not getting the topsoil wet will also help the soil dry out faster. I have one plant that got mold on it that was large enough to me to scrape out the moldy soil and replace it with about 2 inches of rock (i used pon since that’s what i had on hand). you can also use LECA or other rocky “soils”.” ![1개 중 1번째 첨부 파일](https://images.getplanta.com/v1/resize/7SKbucSsa3x7Hc0JE52ZouSTCYSUkYi4knafwIFj7BY/RKNIlyGBRrClPicJbwfvnw.webp?size=large) ### Kailee님이 2025-07-18에 댓글을 남겼어요. Thank you both! I’ll be buying perlite tomorrow! #### fuey님이 2025-07-18에 답변했습니다. To prevent mold, Arbor sells a fungicide in a little purple bottle you can mix with your normal watering water. It helps in preventing it, but it is not a cure for when it is already out of hand. ### BlondeinBrooklyn님이 2025-07-18에 댓글을 남겼어요. Are you using a Neem pest spray or Mosquito Bits? That's how I got mold. I'm using different pest control methods now \& pretty much put some top cover (LECA, pebbles, lava rocks, vermiculite, dry spaghnum -depending on plant) on every plant which addresses both pest eggs \& reduces surface moisture that mold needs. #### Kailee님이 2025-07-18에 답변했습니다. I am! I have a neem spray. I’ll stop this immediately. I’ll look up those other things you mentioned. I’m willing to try anything! #### BlondeinBrooklyn님이 2025-07-18에 답변했습니다. i started using MicrobeLift BMC2 which is a liquid you add to the water you use on plants. Kills any larvae growing in plant. I also am adding systemic granules to new plants which repels most insects as it gets into new growth in the plant \& makes it inhospitable. #### Sunny님이 2025-07-18에 답변했습니다. Neem oil is a good natural pesticide. I would continue using it. I’ve never gotten mold from neem oil or mosquito bits. I have over 200 plants in a high humidity zone 9 area. Mold (Fungus) grows easily on continuously moist soil especially soil with rich organic matter like peat moss. Low air circulation and low light can contribute to the growth. Higher temperatures can increase the chance of growth. A commercial fungicide can kill the mold. Changing the soil to one with better drainage (include coco coir, orchid bark, perlite), letting the soil dry down or dry out between watering and increasing air circulation around the plants can decrease the likelihood of growing mold. 🪴🍀 ### Kailee님이 2025-07-18에 댓글을 남겼어요. Thank you so much! ### Mermaid님이 2025-07-19에 댓글을 남겼어요. You can also do a 3% hydrogen peroxide diluted mix, and spray the top of the soil. The mold goes away, and it helps with pest control. --- _Planta 커뮤니티 (https://getplanta.com). 누구나 읽을 수 있습니다. 게시물을 올리고, 댓글을 달고, 좋아요를 누르려면 Planta 앱을 다운로드하세요: https://getplanta.com/download_
