I've had this plant for a while in other countries, and it was always very easy going. But after the last time I moved the sapling I took with me has started struggling.

The picture is not a perfect illustration, but you can see new leaves coming out turning black in the ends, and eventually drying out and dying. This already happened with a lot of leaves that I cut off, but now it's repeating itself with the new ones.

The plant has been in a relatively bright spot and I think it has received enough water that it shouldn't be the problem. The black parts are completely dead. Does anyone have any idea what can be done? :)

I'm sorry the picture is not more illustrative.

Using rainwater has always solved blackened tips for me. Forgot the class, but my professor was talking about how plants will move the chemicals in tap water to the leaf tips to get rid of them.

If collecting rainwater isn't practical, fill a wide-mouthed pitcher with tap water and let it sit for a day, preferably in the sun.

This could very well be - I think it wouldn't be the first time plants respond poorly to the water here. And it seems to always be starting at the tips very specifically. I'll see if I can find some way to collect rainwater - thank you! Will probably do all my plants good to be honest.

I have a huge plastic tub stashed in the woods behind my house, bring it out twice a year or so before a storm. For storage I have 10 or 12 1.5L vodka bottles a friend gave me.

It would be faster to collect the runoff from the roof, but no idea what chemicals or minerals leach into that. My little pond under the eaves gets refilled with that water and it's super healthy. Frogs everywhere!

Is it about chlorine? Cause my tap water doenst have any added chemicals, just a bunch of limescale

[–] evasive_chimpanzee@lemmy.world 5 points 19 hours ago

Hard water can build up in the soil. There's some plants I've had in the same pot for a long time where the top of the soil starts to look a little "crusty", even though i don't have particularly hard water. If you have a lot of lime scale, your water pH is likely high, which can make it hard for plants to pickup nutrients.

[–] massive_bereavement@fedia.io 3 points 19 hours ago (1 children)

AFAIK limescale shouldn't affect most plants, but some are sensible (not your pothos).

[–] Zwiebel@feddit.org 2 points 14 hours ago

Ironically I made my potos suffer quite a bit until recently

[–] shalafi@lemmy.world 2 points 19 hours ago (2 children)

You sure nothing is added to your tap water? I guess I assumed all municipal water supplies were treated, in any given country.

[–] Zwiebel@feddit.org 3 points 14 hours ago* (last edited 14 hours ago) (1 children)

I looked it up, their internal test report says Cl^- 58mg/l. Looking around online this seems super high, but maybe thats because of the difference between chlorine and chloride?

Anyway apparently they pump it from groundwater wells and just run it through carbon filters

[–] shalafi@lemmy.world 2 points 11 hours ago

That sounds great! For humans anyway, maybe not so much for plants. Thanks for looking and learning me something!

[–] teft@lemmy.world 3 points 19 hours ago

They might have well water.

[–] massive_bereavement@fedia.io 5 points 19 hours ago (1 children)

My checklist for pothos tends to be:

  • Direct sunlight would burn leaves.
  • Roots rotting due to over-watering (if you raise the internal pot that has the draining holes, does it leak water? if you stick a chopstick in it before watering, is it wet?)
  • Lacks proper drainage. (I tend to add an inch of volcanic porous stones at the bottom of most pots allowing them to keep some spare water but not soaking their root soil; adding a draining method at the end).
  • Under-watering can also have a similar effect (is the top soil very dry almost dusty?)

Unlikely cases are improper soil or over fertilized or under fertilized soil (Pothos tend to express it differently in my experience but your mileage might vary). Additional unlikely cases are temperature and overgrown its pot (based on your feedback to Zweibel, I understand that's not the case).

Watering is tricky because if I see the plant reacting negatively to a different problem, I tend to over-water it and now the plant has two problems, which I tend to keep over-watering it hoping that will solve it all. Run the checklist and also try switching its place.

[–] cabbage@piefed.social 3 points 19 hours ago (1 children)

Thanks - that's a super useful check list. I think I'll get some porous stones and re-pot. I'll also move it away from the window to a place with more indirect light, and try to collect some rainwater. :)

[–] massive_bereavement@fedia.io 4 points 18 hours ago (1 children)

I made a crude diagram, but probably you can try easier options before doing any of these things:

  • Soil cover is only useful (beyond aesthetics) if you're experiencing issues with the top soil or if it is drying too quickly due to direct sun exposition. (I don't think this is related).
  • Soil aeration can help you soil become healthier with good bacteria, but if your soil mix is good enough it shouldn't matter (and Pothos are not that picky IMO).
  • Volcanic rocks are layered enough that if you over-water, let's say an inch, the plant soil won't become soaked. It also has the bonus of having some emergency water for plants in some cases. The main con is that it reduces soil for your plants. Allegedly, it provides minerals for plants, but IMO that's wishful thinking.
  • Drainage is a good learning method, as if the tray has water (again IMO), it means we're over-watering.

Maybe someone can correct any of these points and I can improve my caring.

That's amazing - thank you!!

[–] Madison420@lemmy.world 6 points 20 hours ago (1 children)

What is it.

What's your watering schedule.

What's your humidity.

Generally speaking though it's underwatering, if you went from high humidity to low that could explain it.

[–] cabbage@piefed.social 2 points 19 hours ago

My watering schedule is a bit messy, I usually just feel the soil and water when it feels dry. I thought first it was underwatering, but then after cutting off leaves that all came out badly (and only growing worse) to let it re-grow we were being more careful to water it, and still they come out the same way.

The plant has been in this climate for over a year now, but this has been a problem only the last few months or so. So it seems to me to be something more going on than just the watering schedule - in the past under-watering would lead to old leaves dropping, but new leaves would mostly be fine.

[–] Zwiebel@feddit.org 4 points 20 hours ago (1 children)

When did you last repot it? It might've just gotten root rot, I'd check that

[–] cabbage@piefed.social 5 points 19 hours ago (1 children)

A few months ago - during winter, so it's possible that I over-watered it as it's a very different (colder and darker) climate from what I've kept the plant in before.

If it's root rot, I should just repot it and clip off any bad looking roots in the process?

The fact that they came back looking bad again makes me wonder if this might be the case. It didn't use to respond to under-watering like this in the past (older leaves would die), and I don't think I have been over-watering it lately either.

Jup :)

You can also try to get a better draining soil mix like an 'aroid mix'

And of course your pot needs to have holes in the bottom

[–] noretus@sopuli.xyz 4 points 20 hours ago (1 children)

Disclaimer: I'm not an expert.

Pothos is usually fairly hardy. It's probably acclimating to it's new environment. Be very careful of over watering. Stick your finger deep into the soil and don't water if it's clearly moist. If it's totally dry, take it to the shower, get it totally wet but let all the excess water drain. If you haven't repotted it in two years, you may want to do that and check for root rot while you're at it.

[–] cabbage@piefed.social 3 points 19 hours ago (1 children)

It's been repotted fairly recently, and the problems seem to have started shortly after really. Maybe it needs to get used to the new pot, but all the new leaves start looking bad after a little while at this point, and the part of the plant that's already grown seems to be gradually getting marks and looking worse.

Thanks for the advice on watering - I'll be more hesitant going forwards! Could very well be that I have been over-watering it, in the past I got the impression that I could do nothing wrong with it.

[–] assaultpotato@sh.itjust.works 4 points 19 hours ago

I'm actually having a similar problem. I've had my pothos for maybe 6 years now, and I reported them for the first time in a long while a month ago... they're not very happy now, but I'm hoping they're just adjusting.

I have no advice but I hope yours recover!
