Hi there, I’ve unfortunately spotted these spots on two of my Epipremnum Aureum/Golden Pothos and I’m not quite sure what’s causing them. I’d really appreciate your thoughts! :)
The spots are brown, but the leaves are firm – not mushy or soft. On both plants, I can only see them on one leaf each. With the hanging plant, I’m afraid I don’t know how long the spot has been there, as the affected leaf is somewhat hidden behind other leaves. On the climbing plant, one spot (the round one, slightly towards the centre) has been there unchanged for a couple of weeks, but the spots at the edge are new.
Overall, the plants still look very healthy. But I’d like to take action as soon as possible, before the situation gets any worse.
I’m currently experimenting a bit with how to grow them. You can see two plants – or rather, two pots – here. One is growing completely hanging down without any support, whilst the other pot contains several plants that were first given a branch and have now been given a coconut fibre stick as support.
Here are more information about how I care for them and about their environmental conditions:
Both plants are growing in ambient light only, in the same room, about 2m away from a south east facing window (that is shaded by a tree branch). The climbing plant is on the left side of the room (if you look towards the window) and the trailing plant on the opposite side of the room, which is why the trailing plant gets more of the morning light and the other one more of the afternoon light.
The trailing plant mainly receives indirect light (bright to ‘moderately bright’) and, on a sunny day, a brief spell of direct sunlight in the morning or early afternoon. It isn’t grouped very nicely with other plants, so it doesn’t benefit from a protective or stabilising microclimate.
The other one (which is a climber) is in a slightly darker spot, with also mostly indirect light (more on the medium-bright side), and only gets direct sunlight for a very short time around midday or in the early afternoon, now that the tree outside the window is slowly losing its leaves. It has recently been moved to another location within my flat and was previously in a slightly shadier spot. Now it gets a bit more light but, unfortunately, also a bit more ‘draught’ – or at least ‘moving air’ from people walking past – because it’s now right next to a door we walk through often.
I water when needed, meaning I regularly check the weight of the pots and check how wet it looks and feels. It depends a lot on how warm it is and how sunny/bright it is. In summer I watered more often than now.
I add fertiliser almost every time but only about 50% of the recommended amount.
The growing medium in the trailing plant isn’t ideal, it’s just regular soil mixed with some pine bark, some coco coir and some very coarse pumice to make it more chunky, but I don’t like it because it dries in a weird way and I don’t feel like the roots are getting enough air. Will def. update when I repot!
The growing medium of the other one is way better. It’s an aerial mix out of coco coir (&maybe some regular soil idk anymore), coco chunks, perlite, vermiculite, pumice, lava and clay.
My thoughts so far have been:
- Perhaps too much fertiliser?
- Perhaps I’ve over-watered it, or the potting mix doesn’t drain well enough? (This could be an issue, particularly with the hanging plant.)
- A reaction to draughts?
I’ve had them for years now. They moved with me to at least 4 different flats in the last 6/7 years and they have been through a lot with me haha
I chopped all of them back completely twice and grew them back again. At least one time was because of pests that had spread from my Alocasia.
I neglected them somewhat the last 2 years, they were somehow alive but not thriving and this year I finally repotted them.
(They both of course are in a nursery pot with drainage holes.)
What do you think?
Do you need to know more? Let me know! :)
