Yes, you can 100% grow a Monstera Deliciosa successfully in water IF:

  • You change the water frequently
  • You clean the soil off the roots well
  • You fertilise it using a fertiliser that’s suitable for hydroponics
  • You grow it in an aquarium (top marks if your boyfrind maintains said aquarium):

Can you grow a Monstera in water?

In a word, yes.

I see this question asked on Facebook groups all the time, and there seems to be equal number of people arguing for yes or no.

So I decided to try it myself.

I bought myself a baby Monstera for the princely sum of £4.99, washed off the roots, and popped him in a very professional hydroponics set-up consisting of a San Miguel pint glass and some tap water.

He’s doing fine. A leaf was unfurling when I bought him and it’s come out fine. Water roots are growing well and are already threatening to break out of the glass.

I have a video all about growing Monstera in water here.

Why would you want to grow a Monstera in water?

Ok, aside from the pros I listed below, I think that it looks really cool. It’s also a great way to utilise clear vases in a unique way.

You may see clear vessels being used for Leca on Instagram, but semi-hydroponics systems need to be flushed every few weeks to remove mineral build-up, so most people using Leca in vases drill a hole in the side.

You don’t need to do that if you’re only using water.

Pros of growing a Monstera in water

  • It’s less messy than soil

I have a small house and a lot of plants.

There’s soil EVERYWHERE.

(I also have two house rabbits, so there’s hay everywhere too. My poor vacuum.)

You’ll know if you follow my Instagram that I’m currently trying out passive/semi-hydroponics. I have a full guide to getting started with leca here.

Sure, it’s important for me to try new things so I can help you guys, BUT the lack of soil and mess is real appealing.

  • It’s cheaper over time

Soil is expensive enough, without going to the hassle of making up your own bespoke potting mix. Water is far, far cheaper – even if you go for an expensive RO unit.

  • Growing plants in water reduces pests

Another reason I’m interested in hydroponics.

Growing plants in water can reduce some pests (like gnats, that lay their eggs in the soil and eat decaying matter in the soil) to almost zero.

Whilst it’s less effective on pests such as thrips and spider mites (that I’m currently battling – some plants have both. It’s fine), it’s easier to treat plants for pests when they’re in water.

You can really blast them with the showerhead of the hose without worrying that you’re making a mess or wasting soil.

  • You can check the roots really easily

I mean, they’re right there. Just look at ’em.

Even if you’re not growing your plants in clear receptacles, you can just take the plant out and have a look.

When you initially transfer your plant from soil to water, you’ll need to keep an eye out for root rot and trim off any as soon as you see it.

If you’re a bit confused about why plants grown completely in water don’t necessarily get root rot, I explain that here (it’s all to do with bacteria and oxygen).

Cons of growing a Monstera in water

  • It can be massive ballache

Ok, it isn’t for me, because I have an aquarium. Every week or so I replace the water with fresh aquarium water, and do little else.

But if you don’t have an aquarium, you’ll need to change the water frequently and add fertiliser. Whilst you could just use regular fertiliser, plants grown in water need micronutrients as well as the macronutrients usually found in plant fertilisers. I recommend using the General Hydroponics Flora series, which you can get on Amazon.

  • You end up with algae

Algae is unlikely to have a negative effect on your plant, but it looks pretty gross, and is nigh on impossible to prevent.

DO NOT be swayed by people that tell you that a fish will help. Not only is it cruel to keep a fish in an unfiltered, unheated tank, IT WON’T HELP.

Take it from someone that’s had fish for over a decade – very few fish/snails will eat algae effectively. They’ll eat their delicious fish food instead.

Combat algae by growing your plant in an opaque pot and washing out the vessel often.

Tips for growing a Monstera in water

  • Clean the roots properly

I’m not the most patient at this, but I’m getting (a bit) better.

When you transplant a plant from soil to water (or leca) it will grow water roots, and eventually shed its soil roots.

If you leave too much soil on the plant’s roots, it’ll stop oxygen from getting to the roots and cause root rot.

  • Increase light, temperature, and humidity

This is good advice for any time you change something in your plant’s life.

By increasing the light, temperature, and humidity, you can give your plant the extra energy it needs to help stave off shock.

That being said, be careful not to burn your plant or let it overheat. Don’t put it in direct sun or expose it to temperatures of over 28C/82F.

I’m going to build myself a little propagation box with a grow light so I can more easily control this. I’ll do a post on what I used when it’s finished and tested.

  • Use the right fertiliser

One specifically for hydroponics, since your plant won’t be getting any nutrients from the soil. As I mentioned before, I use General Hydroponics.

You may need a pH test kit for this if you’re planning on keeping a lot of plants in water. If the pH isn’t correct then your plant’s ability to take in nutrients can be compromised.

In my experience, Monstera are pretty easy going on this front, so it’s probably not necessary if you’re only planning on keeping your Monstera in water. I haven’t added any fertiliser bar fish poop.

How to clean off your Monstera’s roots properly

Like I’ve mentioned before, Monstera are tough cookies.

I did a crap job of cleaning my Monstera roots before popping him in his glass. I rinse the roots under the tap every time I change the water and there’s STILL soil coming off. I suppose the hardened stuff will take a while to soften.

Step 1:

Remove as much soil as you can with your fingers. Be as gentle as you can BUT some roots will snap. I snapped LOADS and my guy is fine.

Step 2: Using either a hose or tap, blast the roots. Start of gentle and increase the pressure.

Do this into a bucket/washing up bowl. Getting a lot of soil down the drain will not help your plumbing at all.

Step 3:

Once the bucket or whatever is full, turn off the water and soak the roots in the accumulated water for a bit, and try to get off any remaining soil.

A toothbrush seems to be the weapon of choice here, though I admit I didn’t do this. I will in future though.

Which fertiliser is best for a Monstera grown in water?

As I mentioned, regular plant fertiliser may not be enough for plants grown in water, because they can’t get any micronutrients in the soil.

If you’re only looking at keeping one plant in water, I’d stick to the usual seaweed emulsion. I don’t think it’s worth forking out for fancy fertilisers for one plant. If your Monstera looks like it’s suffering then you might want to consider investing in hydroponic supplies, or you could just put it back in soil.

Here are the supplies I use/recommend:


I put a couple of drops in the water when the plant is first put in water. It helps with transplant shock. It’s good to have if you have a lot of repotting to do.

Hydrogen Peroxide

I haven’t got any yet, but it’s only my list. If your plant develops root rot, cut off the affected part and then wash the remaining roots with hydrogen peroxide to prevent further rot.

To be honest I could do an entire post on the uses of hydrogen peroxid in plants, but I want to test it out for myself first.

General Hydroponics Nutrients

This is a set of three nutrients that I use for the plants I have in Leca. I haven’t used them for my Monstera because of the fish poop, but I’m interested to switch over at some point and see if it makes the plant grow faster.

Ph up and down

Like I said, this isn’t necessary if you only have a couple of plants, but if you’re interested in the Leca life, then go may want to invest in this.

At this time I have no idea how important pH is, or if it’s just best practice. I’ll let you know when I have more of an idea.

monstera leaf

Will Monstera grow faster in soil?

Yes. No.

There’s no way of knowing. A plant that’s well looked after in water will grow faster than a poorly cared for one in soil.

Light and humidity are really the keys to fast Monstera growth.

I might pick up a similar-sized Monstera and put them in the same conditions and have a very slow, very boring, race.

Would I recommend growing a plant in water?

I think it’s fun and it looks cool, but it’s really up to you.

If you’re the kind of person that will ignore your Monstera for weeks on end, I’d probably suggest that you leave it in soil.

But if you constantly struggle with overwatering and love to spend a lot of time caring for your plants, hydroponics may be a great thing for you.

Growing house plants in aquariums

My Monstera Thai Constellation is currently growing in my aquarium and she’s doing so so well. The great thing about growing a plant in an aquarium is that a lot of the issues like watering, fertilisation and humidity are solved by the tank.

Plants in aquariums obviously don’t need to be watered, they get plenty of nutrition from the fish poop, and the humidity immediately above a fish tank is quite high.

One of the issues is that you need to have an open-top tank to fit the plants in, and to do that you need to ensure that none of your fish are jumpers/escape artists. Do a roll call every morning if you’re unsure!

The other issue is keeping the plants upright and stable. We have a little plastic ring clipped onto the side of the tank, but a lot of people swear by slicing up pool noodles to serve as little plant holders.

I also, I’m ashamed to admit, pegged her up in the beginning:

Final thoughts

Monstera are pretty resilient. They’re also cheap if you want a tiny one. If you want to try growing a Monstera in water, don’t try with the 50-year-old one your grandmother gave you.

Go and buy a cheap one. If you can’t find a cheap one, go for a golden pothos or something, give that a go.

Don’t rush out and buy a tonne of nutrients, unless you’re like me and have decided on a whim that switching to semi-hydroponics is your new thing. At least wait until I’ve made all the mistakes first.

  1. Great article! Not many out there on this topic at all. In the process of transferring my plants from soil to Leca or just propagating cuttings, I always put them in water for a few weeks but they end up doing so well in water that I leave some of them in there! With my Monstera Deliciosa I have gone back and forth. I left her in water for months and then decided to put her in Leca. She is doing fine but I want to put her in a larger pot so for now I stuck her back in water. I feel like I will always use water as a safety net since they all do so well in it. I do use the GH Nutrient set but being winter time I haven’t really gotten into a good schedule as of yet, so I’m just going with less is more right now. Thanks again for sharing these tips With others!

  2. I’m really bad at not adding nutrients in winter – I find plant maintenance in general waaay more than a chore. I’m planning on moving my big monstera into Leca because I want to find out the easiest way to secure a moss pole – the one annoying things about Leca is how much it moves about!

  3. This is the best info I’ve found!

    I bought a monstera (that was incorrectly labelled) and two other unknown plants from a garden centre and they’re all growing in water but had clearly previously been in soil. They’ve been doing great on just tap water alone for about 8 months now.

    I have a few questions:
    I had no idea about the aquarium thing! Do I just put some of the aquarium water in with my plants? There are plants growing in the fish tank and at some point nutrients were put in but not recently.

    What happens if you take the plants out of water and put into soil? Do the water roots drop off and soil roots grow? Does the plant wither during that period of transition?


  4. Thank you! I’ve actually just cut out the middle man and put my monstera into the aquarium- my boyfriend has glued plants to the back of the tank so I just wedged the roots into them and the leaves stick out the top. Fortunately the lid is just a piece of glass and there’s space at the back.

    But yeah, the aquarium water is great to use for your aquarium – not only does it have nutrients (from the fish poop – you don’t have to add any), but it’ll (hopefully) have dechlorinator added.

    When you transition the plant will grow soil roots, but I think (not 100% sure) that water roots can work to some degree in soil. It’s still important to keep the soil more moist than you normally would for a few weeks when first transitioning, to give the roots time to adjust. I’d also use an airy soil mix (add in perlite and orchid bark) to ensure the roots don’t suffocate.

  5. Thanks for the reply Caroline.

    I can’t believe they’ve survived this long on hard tap water haha! I will clean and use some aquarium water today.

    Also, I took a cutting from my monstera and left it in the water to grow roots but nothing has happened for a few months. I popped it in damp soil and it shriveled up so I put it back in the water and it’s looking more lively but still no roots. I’ll keep in the water until roots have appeared then dry soil again but keep it quite wet like you suggested.

    Thanks a lot! Super helpful

  6. If you’re cleaning the filter, the gross water from that will be awesome for your plants! Monstera are pretty resilient, so hard water won’t faze them! Wait until you have a couple of inches of roots before trying soil, and use a nice airy mix. The reason a lot of cuttings die when transferred to soil is lack of oxygen.

  7. Thanks so much!

    My boyfriend has kept fish for many years and there’s still so many stores selling unsuitable fish. It’s heartbreaking.

    Bettas are such great pets – they need to be kept singly (or females in small groups) and are small so don’t need THAT big a tank (compared to other commonly available fish like clown loaches and angel fish), they have amazing personalities, and they’re beautiful.

    Seeing them kept in cramped, unfiltered, unheated tanks is so sad. My boyfriend recommends that a betta is kept in a 40l+ tank. Although he wouldn’t recommend them as a great fish for beginners – something like a baddis baddis (we have one that call baddis the bad ass because he’s tiny but rules the big aquarium) or even cherry shrimp would be a better option.

    Interestingly, we have a type of killifish that lives very happily in a 27l (he’s about 1cm in length) tank with no heater or filter (they live in small puddles in the wild) perfectly happily. They’re blue with silver spots (v v pretty) and is so so easy to care for but aren’t very widely available. Like bettas, they’re v aggressive so just be kept singly.

    Most killifish (most fish tbh) require a heated, filtered tank so I don’t understand why the species we have (paraaphanius mento) is only kept by a very niche group of aquarists. He’s so easy and he’s the cutest little character!
