Post the pictures in the comments. We could really use them to help you.

So I'm not entirely sure what's going on, but for some reason every time I've tried to upload the photos, the photos do not go through. I can't even upload using the Houzz photo option so my last resort is to upload through Dropbox. If you click on the links, it'll take you to the photos directly.

I had reached out to the owner and asked what could possibly be happening, and he originally thought I was overwatering, but I've only watered twice. When I do water it, I get the soil just wet enough, not soggy.

What kind of spray would you recommend? I am wondering if I do need to trim it too. It will be my last resort if I can’t save it within the next few days.

I got two starts from ebay, they rooted(took for ever) but mine are nice and green. I don't think yours are too healthy. Have you watered them at all? They like sun,since they are tropical. Are they rooted yet? Don't need to water much if no roots. Good luck.

Thanks Sharon. I bought this one through Etsy and the person seemed reputable. I even asked the person I purchased from and he even said he had not seen this before. I reached out to another person that I purchased dragonfruit cuttings from and he said the yellow version is different to maintain than the physical graffiti kind and recommended me to cut the brown area off and cover with cinnamon, and put it in slight shade since it’s a baby (The second guy seemed like he knew a lot more so I took his word for it). When the yellow dragonfruit arrived, I had it in the shade for a few days and afterwards, i put light fertilizer and brought it out in the sun. I’ve watered a few days ago and tonight I plan to water again when it cools down since the soil is dry again. I also put sprayed fungicide as a precaution.

If this one doesn’t work out, I‘ll definitely try again since I know not all plants can succeed the first time. I’m crossing my fingers that i was able to save it by trimming off the bad section. Maybe I could try EBay as well.

Good luck!
