If it’s a fungus, like black spot, you need to use NEEM oil as a spray for four times in a row; that’s every 7 to 10 days for four times. I’ve had to do that several times, and I just put it on my calendar to remind me. Also, if this plant does have something like black spot, and it’s near your other plants, it’s quite contagious, or so I found; that means all your plants need to be in your spray program. Best of luck! #### plantluvr444님이 2025-05-03에 답변했습니다. unfortunately i no longer have the neem oil it's in storage. what's another alternative? #### Lynda님이 2025-05-04에 답변했습니다. I would suggest buying a small bottle of NEEM spray at your local hardware or box store. It’s definitely not expensive, and might help you treat your plant. If we were close, I’d gladly give you some of mine. In fact, where are you? TIA! #### KJM님이 2025-05-04에 답변했습니다. There are other fungicides available as well as neem. Also the brown spots will not go away. You will stop the fungus from spreading but the damage done is there. #### plantluvr444님이 2025-05-04에 답변했습니다. never heard of TIA but thank you for the offer. i'll just have to find some at my local store #### BigGrac님이 2025-05-04에 답변했습니다. I think she meant TIA as in “thanks in advanced” - don’t want you to spend time searching for it in the store lol ### KJM님이 2025-05-04에 댓글을 남겼어요. I read an interesting bit of information recently. If you put piece of pothos cutting into a pot with another cutting it gives off a growth hormone that stimulates root development. The same thing for willow but you make some kind of a tea with the willow. I forgot exactly how you make the tea I know it involves boiling water. #### plantluvr444님이 2025-05-04에 답변했습니다. i've read the pothos thing too and i've tried it definitely helps #### Wolfen 🐺님이 2025-05-04에 답변했습니다. All cuttings will give off rooting hormones after a week or two. But then everyone says change the water weekly, kinda defeating the plants biology lol. Pothos generally excreted these hormones quicker and more abundantly that other plants. Hence the putting them in with hard to root plants vs using a rooting hormone #### Lynda님이 2025-05-04에 답변했습니다. The tea you are speaking of is made from boiling willow bark in water, which will then have salicylic acid in it; it is similar to aspirin, and has the same health properties. I think it’s good for what ails the body! #### Lynda님이 2025-05-04에 답변했습니다. Wolfen, do you recommend NOT changing the water in your prop pots? I do use a tiny bit of Prop Drops in with my props. TIA! #### Wolfen 🐺님이 2025-05-04에 답변했습니다. I honestly almost never change mine unless until the get gunky. And use prop drops as well. But I also sanitize my props. _앱에서 2개의 답글 더 보기_ ### cherrbear🐻님이 2025-05-04에 댓글을 남겼어요. are those brow dots 3-dimensional? can you scrape them off or is it a discoloration in the leaf? #### plantluvr444님이 2025-05-04에 답변했습니다. i can scrape them off #### Lynda님이 2025-05-05에 답변했습니다. Sounds easy, peezy! Does that mean if I do that the ends of the cuttings won’t get icky, you know that snotty gooey look? TIA! #### cherrbear🐻님이 2025-05-11에 답변했습니다. if you can scrape them off it might be scale. scale is a bug so the plant would need to be pest-treated \& kept away from other plants. that was my initial thought when i first saw the picture. it’s been a while since i last commented tho, have you figured out the issue? ### Wolfen 🐺님이 2025-05-04에 댓글을 남겼어요. If it is fungus neem isn't going to do anything for it. 1:3 peroxide: water dilution sprayed on or wiped on with a saturated cloth every 3 days. This could also be pest damage, especially if it's appearing quickly #### Lynda님이 2025-05-04에 답변했습니다. Then why is the recommendation always to use NEEM, or a copper fungicide? I’ve been fighting with black spot for months, and now I’m using copper fungicide. What do you know about using hydrogen peroxide for black spot? Please spill the beans! TIA… #### Wolfen 🐺님이 2025-05-04에 답변했습니다. Because people go gaga for neem. But it's not very efficient against much beyond spider mites amd soft bodied pests. Copper fungicide works fairly well on fungus, but it is limited on types it treats. I use peroxide dilution or physan-20 personally, if i suspect fungus or bacterial. As it's a more broad range fungicide. #### Lynda님이 2025-05-04에 답변했습니다. Thanks for the beans… I don’t know how you know so much, girl! Which treatment do you prefer, and why… the peroxide dilution or PHYSAN-20? PS. I’m pretty sure it’s black black, but how do I know if it’s fungus or bacterial? You’re probably gonna say if it’s black spot, it’s fungal, right? Why am I having so much trouble beating this stuff? TIA! #### Wolfen 🐺님이 2025-05-04에 답변했습니다. I prefer physan 20, mostly because it's more broad spectrum, and covers bacterial. The biggest difference is bacterial is very fast. Like if you see something one day. And the next day it's worse and the day after that even more so. Most likely bac over fungal #### Lynda님이 2025-05-05에 답변했습니다. Well, I searched Amazon and found the following. Can you tell me which of these you prefer, and why? One thing I couldn’t find out, and that is if it is dangerous to use. They wouldn’t even give me any information about whether it was safe to use around pets or not. Do you know what the safety parameters are? TIA! PS. Those two look alike bottles looked like they were different products when I checked on Amazon; now I don’t know if they are or not. ![3개 중 1번째 첨부 파일](https://images.getplanta.com/v1/resize/ogsS0GJIvWBzx7CvItnCsicGb0YTD2umkWf-CRAbvzU/pbUKs8UrRrGeVFUN9jfxjw.webp?size=large) ![3개 중 2번째 첨부 파일](https://images.getplanta.com/v1/resize/ogsS0GJIvWBzx7CvItnCsicGb0YTD2umkWf-CRAbvzU/Jsxfhyd8QliRAExSoQfgkQ.webp?size=large) ![3개 중 3번째 첨부 파일](https://images.getplanta.com/v1/resize/ogsS0GJIvWBzx7CvItnCsicGb0YTD2umkWf-CRAbvzU/gDjPu8i4ShqU7avN3FsdQg.webp?size=large) _앱에서 3개의 답글 더 보기_ ### Wolfen 🐺님이 2025-05-05에 댓글을 남겼어요. If you scrap them off are they squishing, like it's a scale bug? Or powdery like a mold/ mildew/fungus? #### plantluvr444님이 2025-05-05에 답변했습니다. it was kinda powdery but i just cleaned it again. i'm thinking it's some kind of mold. i had to cover the nodes with candle wax but there's roots growing so they should be okay for now --- _Planta 커뮤니티 (https://getplanta.com). 누구나 읽을 수 있습니다. 게시물을 올리고, 댓글을 달고, 좋아요를 누르려면 Planta 앱을 다운로드하세요: https://getplanta.com/download_
