How to Care For Aglaonema

In my opinion, Aglaonemas are woefully underrepresented in the house plant community. They’re easy to care for and come in some pretty spectacular forms – I mean, check out the one above! It’s freaking PINK.

Basic care:

  • Light: bright, indirect – medium
  • Humidity: 50%+
  • Temperature: 18C/65F – 24C/75F
  • Watering: Water thoroughly when moisture metre reads 2/3
  • Fertilise: general purpose fertiliser, monthly
  • Potting medium: house plant soil with perlite
  • Propagation: seed, division, cuttings
  • Pests: mealybugs, aphids, scales and spider mites
  • Bloom? yes, quite readily. Spathe and spadix
  • Toxic? yes

I’m not entirely sure about the plural of aglaonema being aglaonemas, but Google and Grammarly appear to be in agreement, so aglaonemas it is.

Quick note: my first aglaonema was bought by my boyfriend from the discount section of the garden centre. It was droopy and sad, but apparently pest free. I suspect overwatering and lack of humidity was the culprit, so don’t disregard a bargain. Just check it for pests and keep it in isolation for a couple of weeks.

Where do Aglaonemas come from?

Aglaonemas grow wild in the rainforests of south-east Asia – Thailand, Indonesia and Malaysia. The name Aglaonema means ‘shiny thread’ in Ancient Greece, apparently due to their shiny stamens. Alrighty then.

I do not know why they’re commonly referred to as Chinese Evergreens, and neither does Google.

Where should I put my Aglaonema?

ANYWHERE.

Jokes, they like partial shade, but a bit of indirect bright light will be appreciated.

Aglaonemas don’t need to be on a windowsill, so experiment with any bare corners you have to see if it’ll thrive there.

Light conditions for Aglaonema

I’ve read that Aglaonema both can and can’t live under artificial light alone, so I’m thinking that medium light (or a grow light) is best for them.

Remember though, plants convert light into energy, of a bit of bright, indirect light will increase the growth rate of your Aglaonema.

Since they would naturally live beneath the rainforest canopy, the leaves are likely to burn if left in the sun, so put up a sheer curtain if you want your plant near a south or west-facing window.

It’s the general consensus that the more variegation your Aglaonema has. the more light it needs. Mine is, I would say, about 50% variegated, and is about 5 feet from the window (and growing nicely).

Aglaonema temperature preferences

Aglaonema like a temperature range of between 18 and 24 degrees Celcius, which basically translates are room temperature.

Do you see a theme here? They’re not bothered. They just want you to be happy.

Seriously though, Aglaonemas come from the rainforest, so I am aware that here in the UK I can’t exactly leave it near an open window in winter, but it’s also not a plant I worry about succumbing to the cold.

If you look online there’s a lot of talk out there about how intolerant of cold temperatures Aglaonema are, but I don’t think they’re any less tolerant than any other tropical plant. Keep it above 15 degrees C and you’re good.

I mean, I don’t like the cold at all, but it won’t kill me.

Aglaonema humidity preferences

Aglaonemas do like a bit of humidity. Mine grow in my least humid room, though there’s sometimes a spike because it’s the room I dry my washing in (top plant hack!), but it’s also the warmest room.

It’s doing pretty well bar a few crispy tips. However, since I got this from the discount bin I’m not sure if the crispy tips are something I could ave prevented or not.

Ok, I moved my hygrometer into my office (where the Aglaonema is) and the humidity is reading 61%. So it’s fine. Anything above 50% will be sufficient, and 40% will probably be tolerated.

Some of the fancier types of Aglaonema, like the Pictum Tricolor, may require higher humidity, but since they’re so expensive and often poached from the wild, we’ll just stick with the cheap ones.

How to water your Aglaonema

Aglaonemas are pretty forgiving when it comes to being underwatered, which is great for a natural underwaterer such as I. Follow the same watering rules you would for any other aroid – water them thoroughly, but only when they’re pretty much dry.

We’re talking about a 2 or 3 on the moisture metre.

Aglaonema don’t like sitting in water, but they also won’t die dramatically if you’re a couple of days late.

How to fertilise your Aglaonema

I can’t see that they have any special requirements fertiliser-wise, so once a month with a general-purpose fertiliser will do. I usually use seaweed emulsion, but this spring I shall be experimenting with making my own from rabbit poo. I have two rabbits. They poo. Win-win.

Pests common to Aglaonema

Mealybugs, aphids, scales and spider mites. Wheeey. Keep the leaves clean and dust-free using a solution of neem oil and warm water and that can do a lot to prevent all of those critters settling in your Aglaonema.

Potting mix for Aglaonema

Nothing too fancy – a general house plant potting mix cut with some orchid bark and perlite will suit it well, or any premade aroid mix. Aglaonema don’t like sitting in soggy soil, so you want something really well-draining.

What type of pot do Aglaonema need?

They’re not fussy AND they’re pretty slow-growing, so keep it in its nursery pot until you see roots starting to emerge from the bottom or top.

When you do need to re pot, they don’t seem to be fussy regarding pot material. I like the look of terracotta, plus aroids do like a bit of aeriation around the roots. Obviously a drainage hole is necessary to prevent root rot and keep your Aglaonema happy and healthy.

Are Aglaonema toxic?

Yup. Don’t let your cat eat it. Also, don’t eat it yourself.

How to propagate Aglaonema

Apparently it is possible to propagate from leaf cuttings, but the information out there is sketchy at best.

Quite a few people grow Agalonema from seed too, but I’m way too impatient to deal with that.

The most common way to propagate Aglaonema is by root division – just remove the pups from their mother when they’re big enough and pot them up separately.

Mine is actually three plants in one pot, so I could easily split it once it’s a bit older.

Notes

  • Aglaonemas do bloom, but most hobbyists lop the flowers off because they’re not worth the energy expended by the plant. Harsh.
  • They’ve been grown as ornamental plants in Asia for centuries and are thought known to bring luck. This is why I need one of every cultivar. They’re lucky.
  • Apparently Aglaonemas feature a lot in the film Leon. I have never see it.

I bloody love Aglaonema – I’ll take lush, green (easy care) foliage over blooms any day. Go and get one. They’re like a Dieffenbachia I can actually keep alive.

  1. They’re not fussy, as long as they’re not in direct bright light or somewhere super dark. Mine grow well in medium light.

  2. Why are my leaves bumpy and have tears on them? However they are keeping there color in med. light and are not fussy. Love my ag’s. Have lots of their family, silva-bay chines every-green and etc. Forgive my spelling, I never was a speller but I’m a happy plant enthusiast.

  3. First check for pests! Probably not, but just in case. Most likely is that the leaves aren’t liking the amount of water they’re getting when they’re emerging – either room much or too little. Keep an eye out for new leaves and be extra careful about watering.

  4. Am in Jamaica and my aglaonema are doing fine am living in the hills were i have lot of rain especially now and i realize they are very happy,have some i want to repot but waiting until the rain cool down, thanks for your info.

  5. Thank you for this blog. I have an agalonema that is red and was beautiful when I first brought it home. I repotted into a larger pot as I thought it was needing to be. That was about a year ago. It really looks very unhealthy and has never thrived like my other plants. It grows very little and looks droopy alot. I have really watched the water to make sure it has enough and not too much after reading about a gazillion blogs and I fertilize it, but it still looks poopy. I was hoping that it would be big and bushy by now. I am wondering if I repotted it into a smaller pot, maybe I went one size too big? I am really disappointed that it has not done any bettter and it is one of my favs. Any suggestions?

  6. My Aglaonema is currently looking a bit sad, but it’s just because it’s winter. Whilst that won’t be the sole problem yours is looking sad if it’s been a year, it’s likely that it should perk up a bit once the warm weather hits.

    I wouldn’t be too worried about the pot if it’s still alive after a year – especially if you’re being so vigilant about the watering. It’s possible that the plant is putting all her energy into growing new roots to fill up the space before putting out new leaves.

    If it were my plant, I’d check the roots first, to make sure they’re not rotted. Then I’d pop the plant in a warm, bright spot that has plenty of humidity. If you don’t have such a space, perhaps try a grow box on a windowsill. Heat mats, grow mats, and humidifiers help, but a clear plastic box on a windowsill near a radiator/heat source will certainly do!

    If she isn’t growing very much, I’d cut back on the fertiliser, or switch to something really gentle like worm castings. I know it sounds counter-intuitive, but you can resume your normal fertilising schedule once it starts putting out more growth.

  7. Have you tried putting it in a bright spot but putting a sheer curtain in front of it? That’ll let the light through but dissipate it
