Burle Marx Philodendron going yellow
I inherited this Burle Marx Philodendron and it was very happy all summer. I stopped fertilizing one Sept and by Oct, it’s starting to look like maybe it has some sort of deficiency, because the leaves are turning yellow and fading very slowly from the inside out. (See photo.) Do philodendrons do this to make space for new leaves? Is it a nutrient deficiency? Is it unhappy with colder weather? Not sure. Any advice appreciated, thanks!

    Giovanna Fernandes Hi, have you figured out what made your plant turn yellow and has it improved by now? I’m having the same problem with the same plant. I bought it recently and it arrived well. I planted with lightly fertilized soil.

      Julia Barry I'm sad to say I haven't really figured it out, but yeah, our leaf issues look identical!

      The good news for you is, my plant is still very much live, even while some of the leaves have maintained that blanched looking color. So I guess that means that at least I halted whatever was happening from happening to the rest of the plant?

      The things I tried were fertilizing, repotting, changing the sunlight amount and direction... it at least does not seem to be a pest or fungus.

      If you figure anything out, please let me know! I was just looking at that plant the other day and thinking how I really wished I had figured out the issue. ;)

      Good luck!

        Giovanna Fernandes Thanks for your reply! I will try planting it again in Sphagnum Peat Moss, I'll report back if that solves the problem.

          Julia Barry Giovanna, did you have any luck with the peat moss? It's so interesting that we all are having the same issue, but no one has found what helps it quite yet! I've also been wondering if it's a nutrient deficiency that isn't fixed with the specific fertilizer I have. Does anyone know what particular nutrient it might be missing when it looks like this?

            Giovanna Fernandes I re-potted it less than a week ago and the one leave that was turning yellow is further down discoloring. I have new sprouts coming so I’ll see how they’ll do, maybe once the leaf starts yellowing it won’t go back to green...

    Paris Lalicata There's a chance it could be a nutrient deficiency if the nutrients in the soil have degraded already and the fertilizer was supplementing it considering it happened shortly after. Therefor, I would try either incorporating the same fertilizer schedule back for the plant or replenishing the plant with fresh, nutrient rich soil!

      Julia Barry Thanks, will do! I suspect you're right since this plant was neglected for so long before I inherited it, it may have some catching up to do. Just to check -- it's ok to be fertilizing during non-growing season in this case? Thanks!

        Paris Lalicata Yes it'll be safe since it has a deficiency but it'll also be best to increase it's exposure to light as much as you can!

          Julia Barry Got a grow light since my apt isn't the sunniest in winter, thanks!

    Julia Barry Last photo — this was the first one to start to yellow, so it’s paler and farther along with whatever the problem is

      Tonya Hi! I have the same problem. This was mine when I first purchased it. The ⏫above picture was today. Did anything help? How is your plant today? I haven't seen any pests. It is still moist from purchase. Maybe I will change out the soil, bit it seems fine. The stems are healthy as well.
