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! #### plantluvr444 antwortete am 2025-05-03 unfortunately i no longer have the neem oil it's in storage. what's another alternative? #### Lynda antwortete am 2025-05-04 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! #### KJM antwortete am 2025-05-04 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. #### plantluvr444 antwortete am 2025-05-04 never heard of TIA but thank you for the offer. i'll just have to find some at my local store #### BigGrac antwortete am 2025-05-04 I think she meant TIA as in “thanks in advanced” - don’t want you to spend time searching for it in the store lol ### KJM kommentierte am 2025-05-04 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. #### plantluvr444 antwortete am 2025-05-04 i've read the pothos thing too and i've tried it definitely helps #### Wolfen 🐺 antwortete am 2025-05-04 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 #### Lynda antwortete am 2025-05-04 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! #### Lynda antwortete am 2025-05-04 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 🐺 antwortete am 2025-05-04 I honestly almost never change mine unless until the get gunky. And use prop drops as well. But I also sanitize my props. _2 weitere Antworten in der App_ ### cherrbear🐻 kommentierte am 2025-05-04 are those brow dots 3-dimensional? can you scrape them off or is it a discoloration in the leaf? #### plantluvr444 antwortete am 2025-05-04 i can scrape them off #### Lynda antwortete am 2025-05-05 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🐻 antwortete am 2025-05-11 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 🐺 kommentierte am 2025-05-04 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 #### Lynda antwortete am 2025-05-04 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 🐺 antwortete am 2025-05-04 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. #### Lynda antwortete am 2025-05-04 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 🐺 antwortete am 2025-05-04 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 #### Lynda antwortete am 2025-05-05 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. ![Anhang 1 von 3](https://images.getplanta.com/v1/resize/ogsS0GJIvWBzx7CvItnCsicGb0YTD2umkWf-CRAbvzU/pbUKs8UrRrGeVFUN9jfxjw.webp?size=large) ![Anhang 2 von 3](https://images.getplanta.com/v1/resize/ogsS0GJIvWBzx7CvItnCsicGb0YTD2umkWf-CRAbvzU/Jsxfhyd8QliRAExSoQfgkQ.webp?size=large) ![Anhang 3 von 3](https://images.getplanta.com/v1/resize/ogsS0GJIvWBzx7CvItnCsicGb0YTD2umkWf-CRAbvzU/gDjPu8i4ShqU7avN3FsdQg.webp?size=large) _3 weitere Antworten in der App_ ### Wolfen 🐺 kommentierte am 2025-05-05 If you scrap them off are they squishing, like it's a scale bug? Or powdery like a mold/ mildew/fungus? #### plantluvr444 antwortete am 2025-05-05 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 --- _Die Planta-Community (https://getplanta.com).
