Help ! I have recently noticed these darkening spots on my monstera leafs ? They are on the backs of some leafs and it's super weird ? There's no yellowing or browning yet just this dark green spreading on the leafs ? It appears thinner on the areas where the dark green had spread ? What is this?? Thanks !

I just saw the exact same thing on my monstera tonight, along with patches of black on some leaves!! Did you find out what was causing the creeping up of darker color on the undersides?

Hi Will,

Would you please help me identify what's going on with my monstera? I noticed tonight this blackness on a leaf and then saw another leaf was half black and dried out. Then the undersides of several leaves have a darker green creeping up on them. I watered my monstera today but I've never seen any of this before. I'm very concerned it's fungal. I have the plant sitting near an east facing window getting bright indirect to direct light.

I am concerned about my monstera and it's health. Not sure what I can do from here. I have not repotted or done anything besides change the light that it gets. I've had it a few months and it has not gotten any new leaves or grown much at all. The leaves are browning before even opening.

Hi there, I might be late to the party here but have a real problem with my monstera. It has been thriving since I got it in february and now in the last month has suddenly started developing these brown patches. I think it might be sun damage as it is in an east facing window (and we live in Portugal so it is hot at the moment - but has been like this since may). I have not noticed any bugs or pests etc and now have put paper on the window to stop the hot sunshine. I water once a week and once every two weeks with fertilizer. The brown spots have come on leaves that are new since I got her. It may have been over watered in July because I was away and my flatmate took "care" of it... but she assures me that she only watered once a week. Anyway really worried about her. Please help!!!

Dear Mr. Creed -
I need some help with my 3rd gen (propagated) Monstera, fondly known as Planty Junior Jr. I've got him in a west facing window in my office and he did get some direct sun, but with the window closed. The first three leaves from the bottom on the stem are showing tiny yellow spots, with the lowest leaf (Leaf1 in the pix) the worst and showing some tiny brown spots as well, the 2nd leaf (Leaf2) not as bad but trending that way, and finally the 3rd leaf up from the bottom (Leaf3) just showing the same symptoms. So far nothing on the fourth leaf. I'm careful not to overwater or underwater, and have given him a bit of Miracle-Gro, plus a little pelletized Mg and Ca like what you'd sprinkle under hydrangeas. Overall he seems healthy enough, with the upper leaves splitting like they should and air-roots appearing quite a lot (I trim the off every couple months or so). he just put out a new leaf a month ago, and it has already split and is a beautiful glossy deep green.

Any ideas on what could be causing the tiny yellow spots on the lower leaves? They never appeared until I moved him here from home, where he also sat in a window, tho not as bright. He's been in the same pot for several years, and could probably use a bit more soil or even a repotting, but I am concerned about the spotting. Any ideas? A poster in another forum suggested either red spider mites or a fungus of some kind. There are zero indicators of mites - no cobwebs, no little critters on the plant anywhere. But a fungus? Seems odd that it would develop one here in my office where it is the only plant around.

I'm attaching a few photos to illustrate.

WillC said:Rootball refers to the roots and the soil that the roots have grown into. It normally consists of soil held together in a ball with roots throughout. You indicated that you removed most of the original soil, so I'm not sure you really have a rootball left at this point - just roots and loose soil that you added.

I hope it recovers, but I am concerned that damage to the roothairs was done when you removed most of the original soil. For future reference, removing and replacing soil is rarely a good idea.


Good point. Hands on those roots seem to never end well. I soak all my new plants in warm water before potting. But I have learned to just leave what soil that don't come off on the roots oppose to trying to remove it by hand. Older plants, out one pot and into another and fill in the sides.

I'm relatively new to gardening.
I seem to have a similar problem as WKcai.
I already have an existing monstera deliciosa fir the past 3 months which seems to be growing very well so far. I usually keep it in my room by the window. In the photo, I was cleaning my room and just put it out for a while.
I was given a new smaller monstera deliciosa about 3 weeks ago. I noticed that the smaller one has those kind of brown powdery spots that can be easily wiped off. But they leave a yellow spot on the leaves where they have been. And the plant overall doesn't look as healthy.
The bigger one has some on one of the leaves as well.
I would wipe them off with a soft cloth dipped in light soapy water. But they will come back.
Are those some kind of insects or moulds or something?
I don't use any pesticipes. I haven't used any fertilizers yet on those 2 plants.
I have not repotted those 2 plants yet neither.
I was told I should repot the bigger one. I'm still hesitating.

I have two green monstera's and neither like the window too much. They never burned in east window but the new leaves would fall over until moved away from sun. My three monstera's are about 8 ft from east window with good artificial light and do just fine.

Hi,

I'll let the experts weigh in on the spots since your able to wipe them off? Sounds like some type of mold. I wouldn't have the monstera's that close to the window, and do you have a fan blowing in the room?

As for putting your monstera outside I'll link you to a YouTube channel regarding pests. I remember when this guys monstera was thriving and now it has Thrips, sad video. You can view his channel to see what this monstera looked like before.

Hi folks

Hoping you can help with my monstera which looks unwell.

I got it in November, so about 3.5 months ago, and it arrived looking in great shape with healthy green fenestrated leaves. I should confess that I repotted it - I didn't really know that this was potentially harmful - but in so doing I didn't remove any soil, just added a bit of cactus/succulent type potting mix to help fill the bottom of the slightly larger, but thinner, new pot. However it became obvious that the plant didn't fit that new pot super-well and it was difficult to water it by soaking (no drainage holes) so I repotted it back into something resembling the original plastic pot a month or so ago. I think it's therefore now in a second new pot with most of the original soil intact.

In the time I've had it it's developed a variety of yellow and papery brown parts to the leaves with what look like new leaves sprouting from the base, some of which have remained green and healthy-ish, some of which have just turned entirely yellow. The weird thing is, some of the original leaves still look in pretty good shape but some of the others are really quite significantly brown and papery, and others yellow - it's not consistent.

Initially I was paranoid about overwatering so maybe let it dry out too much. Since then I've been fastidiously waiting for the top of the soil to dry out before watering it again - I checked on it today and the top of the soil is still moist about ten days after I last watered it.

I'm in Glasgow, Scotland, so fairly far north (it's pretty dark this time of year) and the plant sits near a north-facing window - all the advice online was to avoid direct sunlight but maybe a complete lack of it, in such extreme latitude, isn't helping? It sits in my office which has some mild air conditioning but it's at a healthy room temperature in the mid-to-high teens all the time. It's been on a pebble tray to try and moisten the air for a month or two.

I'm not an expert but I think this may be the main issue. That sounds a little too long, and is a sign that either the soil mix doesn't drain very well or the pot is too big, and can cause root rot. Pot size looks fine, so I suggest replacing most of the soil with something better. A good general mix is 25% perlite, 35% crushed bark or coco husk chips, and 45% compost or peat or potting soil. You can find a lot of different recipes with different ratios online. If you don't want to disturb the roots too much, you could also repot to a terracotta pot using the soil it's in now and it will dry out quicker also.

While it should do ok in low light, this looks like it may be a little too low. The advice to avoid direct sunlight is in my opinion not the best advice. My Monstera thrives with several hours of direct morning sun on the leaves. Evening sun would be great, too. If you introduce it to a brighter spot gradually, even some direct midday sun may be ok up in Glasgow. More sunlight will also mean more evapotranspiration and the soil should dry out quicker.

Hi I also have a question about my monstera... Someone sent it via mail about 6 months ago. It came with one new leaf forming (the one in the picture) but once that leaf opened up it never became firm like the older leaves... its just floppy- but not really in the way like it needs more water. It has never not been like that. Is it just an age thing or does it in fact need more water? I just didn't think it was water because none of the other leaves have ever drooped. Let me know what you think- thanks in advance!

Still developing leaves can do weird stuff during stress or a change of environment. Raising air humidity might help flatten them out a bit but I wouldn't worry about it unless newer leaves also look like that.

Monstera leaves usually harden off after a week. I have no idea what is going on with yours.

Hi!

Did you remove the plant from the pot to check root ball after purchase? I purchased a 3 year plus monstera from Lowe's about a month ago, poor guy was in bad condition. Completely root bound, no life in leaves, no soil left in nursery pot.

Are you feeding this plant? Big guy need food. Gave mine a little food after repotting. Second watering fed again but more. The plant is on a regular water / feed schedule now and doing well with two new healthy leaves.

Watering. Are you letting the soil slightly dry out between waterings? If in doubt, get a moisture meter if you don't have one. Some of use need one.

Wow, how can WillC keep up with all these 'chiming' in? Poor Will, he is very good w/advice, tho! Hope everyone finds the 'fixes' they need.. I'm having some issues, but I think I can figure mine out, as I have had a real Jungle in my entire house for years and also deal with Orchids and Carnivores...

Thank you @LSDevarg. I know that Monsteras are very popular right now with just about everyone but me. They are sold widely online and they are often just recently rooted cuttings that are not fully ready to be sold, but they are anyway. Also, there are many delivery issues such as proper handling and temperature control. So many things can go wrong before they even arrive. Hence, there are many problems with and questions about Monsteras.

I simply cannot answer all of the individual questions any longer. A search on this site will find lots of previous questions and answers.

In general, keep your Monstera tightly potted with a pot just large just enough to accommodate the new roots that form at the nodes and enough soil to barely cover them. Use a porous potting mix with added perlite and a pot with drain holes. That pot can be inserted into a more decorative planter.

Indoor Monsteras do best close to a window but just far enough away that the sun does not fall directly on it for more than a couple of hours each day.

When properly potted, allow the top quarter of the soil to get dry before watering thoroughly enough that some water trickles through the drain holes. Never let the pot sit in water for more than a few hours.

Misting and increased humidity are not necessary. Fertilize very sparingly and only when it is healthy and growing vigorously. Normal home temps are fine regardless of the outside weather.

Monsteras are naturally vining or trailing plants that don't grow upright on their own. They can be supported by stakes or poles to keep them upright but eventually they outgrow even the tallest poles.

To manage the size of a Monstera, pruning is necessary. Any stem or vine can be shortened to any length without harm to the plant. New growth will emerge subsequently from that vine starting at the node where you make the pruning cut and grow out from there. Monsteras do not send out branches.

Pruned off tip cuttings with 3 or 4 leaves can be propagated in plant water or in the soil at the base of the existing pot or in its own small pot filled with a porous potting mix.

Discolored leaves can be caused by damage to roots during potting, by to much or too little water or by too much or too little light. They are very rarely caused by a fungus or any other disease. It is most commonly a problem with the roots from either improper potting or watering. Discolored leaves never recover so they can be trimmed or removed entirely just to make the plant look better.

Monsteras are relatively pest-free.

I hope this information answers many of the questions previously posted.
