Help wanted for Monstera!!

9 years ago


Hi I have a monstera deliciosa and I've noticed a lot of yellowing around the edges of the leaves. I'm not sure why this is happening and I would really love some help. My guess is lack of humidity. I'm in NYC and it's just starting to warm up but before it was very cold here, 30-50s outdoors, low 60s inn doors, my living room gets drafty and my room is usually heated, however I don't place the plant near the heater. I recently checked the roots and there's no sign of rotting whatsoever. A new leaf even sprouted today but it hasn't unfurled just yet. Some of my aerial roots have also taken root in the soil and has since branched off new roots so I want to make sure I figure out the issue as spring approaches. Please help!!

    Hmmm, how do you water? I mean, how often and do you let it drain afterwards?

    It looks like mine does when it needs water, but it would help to know your watering practices befor suggesting that it needs water....

    Thanks! I water every 10-14days between 1-2cups of water. I'm in New York so the temp in my place does fluctuate and the air is dry. I try to give the soil time to dry out all the way through and I've been better with misting the leaves to help raise the humidity around the plant. I would forget to mist the leaves but I recently started back doing it daily so I'm hoping that helps. I also moved it to my living room which is around 65 degrees daily. I never have the heat on in there so I figured that would be a more desirable atmosphere than in my room where I'm pumping out dry heat from my heating unit.

    Wow okay will do, thank you!! And am I watering it like this every 10 days? The soil was a tad wet from the 1-2cups but maybe not enough as it should be. The roots are in great shape surprisingly.

    Well, you water it based on when it needs it, not by a schedule. I water mine when it dry, but that's not ideal. I just keep an eye on the leaves and when they look a bit droopy, I water.

    If your soil is well draining and not mushy and compacted, you should aim to keep it lightly moist to the touch. But all waterings should be thorough like this. You don't want it sitting in water either, so it is a good idea to take it the sink and let it drain after watering. That's what keeps the plant happy, watered, and not waterlogged.

    im not surprised the roots are in good shape! You've definitely not overwatered them:)!

    When you start watering it regularly (and letting it drain), the growth will take off like crazy. One way to know when to water is to use a wooden skewer or chopstick. Stick it in the soil, and if it comes up dry, water. Or if only the bottom of the skewer shows indication of water, water.

    The key is well draining soil.

    Perfect okay I will do that I have skewers! Thanks so much!! I added more salt-free sand to the soil mixture a few days ago so I think it's good to go! I'll water it tonight.

    Sand ???? What kind of sand? Sand is not good for potted soil. It makes it too compact. What kind of sand are talking about?

  • 9 years ago

    Horticultural sand. I've consulted with a few plantsman and they told me it helps with drainage. There's also perlite mixed into the soil. I only used a tiny bit of sand, maybe a handful.

  • 9 years ago

    Hmmm. Unless the particles are really big, like the size of perlite, sand is not good for potted plants.

    Also, here's the thing: if you are going to add horticultural sand to a potted plant, providing the particle sizes are really big, it should be done at the time of mixing. When you add it to already mixed soil, it won't have the effect of helping drainage. It will just fall in and fill up valuable airspace in the mix that your roots need for survival. Also, I wouldn't add it to a tropical plant in any case. Perhaps a succulent or cactus, but not a monstera.

    You want to everything you can to ensure that the mix stay light and porous. Which is why perlite is a good thing. So, no sand. I know plant folks recommend it, but they really should not.

    So, I'd strongly recommend holding back the sand:).

    I mixed it into some soil I purchased to repot my monstera. I didn't mix in a lot only maybe a handful, if that. There are pieces of bark wood and perlite in there but I will monitor it and if not I will replace the soil. Peat moss is the soil I used. Is that what you'd recommend?

  • 9 years ago

    Bri, the bark and perlite are good additions. I personally would not recommend peat, but it's totally fine to use for monstera if that is what you have. When I do use peat, rarely these days, I do what you did, which is heavily amend it with bark and perlite.

    My only advice is this: if you find that the mix is not draining well or starts to feel mucky, you can repot using the same ingredients sans the sand. Only this time, start with bark and perlite, then add the peat to that mix, so that you end up with a 1:1:1 ratio. It will feel very loose and porous to you, but that is okay. You will end up with a very free draining mix that will allow you to water more frequently, which will, in turn, allow the plant to grow lush and big. More important, the roots will have lots and lots of airspace. This makes them happy. The more water you can get to the plant without making it waterlogged, the happier it will be.

    I hope that makes sense. I didn't mean to overreact about the sand. It's just that it can become very problematic, especially as the mix begins to deteriorate. It can turn a mix into a slurry mucky compacted mess.

    Oh I see well I'll need to add more bark then. Thanks for telling me!!

    Lol, don't worry too much about it now. I think it just needs a good thorough watering to get back online right now. Then later you can think about amending the mix. Don't worry....it looks like a healthy plant that just needs water.

  • 9 years ago

    How goes it? Did it perk up after the watering?

  • 9 years ago

    The yellowing leaves are still there not sure if that'll clear up overnight. However, the new leaf has inched its way out a little more.

  • 9 years ago

    The yellowing will not go away, but the leaf may be okay. Or, it may continue to yellow and drop off. That's fine. As long as the plant is perking up and new leaves are emerging....

  • 9 years ago

    Yes i excited about the new leaf!!
