Philodendron Mamei Light Needs
They do best in bright but indirect sunlight, but no direct sun which can burn the leaves. They’ll be ok in medium indirect sunlight too, a bit further back from the window.
How Often to Water
Check your plants once a week but only water them if the top half of the soil is dry. They can get root rot easily so make sure you don’t let them sit in soggy soil.
The key to caring for this plant is to avoid letting it sit in wet soil, so make sure you have a well draining medium, and you only water it when it is mostly dry, as well as tip out any excess water after watering so it doesn’t get a soggy bottom.
Use a high in nitrogen feed once a month in the spring and summer months to encourage leaf growth.
Add some perlite to regular potting compost to aid drainage. about 20% of the mix should be perlite. This will stop the soil holding on to moisture as much and dramatically reduce the risk of root rot which is one of the biggest issues with a philodendron like this. For more on Philodendron soil see our guide on what to buy or how to make your own: Philodendron Soil.
When To Repot
Repot them once a year in spring to refresh the soil and give the roots more space. If the roots are crowded, give them a bigger pot size, or keep them in the same pot with new soil.
Tip: It is a crawling philodendron, but it likes to climb, so train it up a moss pole to give it structure and stop it sprawling. You can buy them on Amazon here (affiliate link).
60% humidity is ideal. A bit less is ok, but these will flourish if given the high end of household humidity or even a bit more. They can crisp up if the air is too dry and really thrive if given high humidity.
During the day they should be 18°C-27ºC (64-80°F) and try to keep them above 13ºC (55°F) at night. Don’t let them get too drafty or too cold at night in the winter.
How To Propagate Philodendron Mamei
Take a cutting with one leaf and one node, and root it in moist sphagnum moss. You can use other mediums like water, soil or leca, but I find moss is best for rooting. It keep the the node moist to encourage rooting, but also allows air to circulate, and there is much less chance of rot (which you can get with soil). Keep it warm, humid and in medium indirect sunlight. It should root in the next two months. You can then plant it up into leca or soil and treat it as a juvenile plant.
We covered each method in detail in our separate guide here covering mamei water propagation as well as leca, soil and sphagnum moss: Philodendron Mamei Propagation.
Is It Toxic To Cats?
They are moderately toxic to cat and dogs if eaten and can cause a variety of symptoms including vomiting. If you think your pet may have eaten any, contact your vet immediately and seek their advice.

Philodendron Mamei Care FAQs and Common Problems
You can get wilting or dropping of leaves as well as leaf yellowing, and even root rot, which are all due to over watering. If you get yellowing on a mamei then dry out the soil and water it less regularly. Do not over water a philodendron!
The best way to encourage big leaves is to give the plant 60% humidity or so, and give it a moss pole to climb up.
The philodendron mamei and silver cloud, although very similar, can be told apart as the mamei has more green that silver and the silver cloud has more silver on it’s leaves, also the silver cloud has rounder leaves.
There is a lot of confusion here as there are p. mameis sold as silver clouds or ‘mamei silver clouds’, which are philodendron mameis. However there is a similar but a slightly different plant sold as a philodendron silver cloud. I think that it is a hybrid a of the mamei to be honest, but cannot confirm that, if you are a breeder of these, please get in touch. Either way they are both very similar and beautiful silver philodendrons that are easy to grow.
You can tell the difference easily between a philodendron mamei and a sodiroi by looking at the petiole (the stalk that attaches the leaf to the main plant). It is green on the mamei and a reddy green on the sodiroi. The sodiroi has much more silver on it too, the leaf is majority silver covered, the mamei’s leaves are more green than silver.
The Pastazanum Silver are generally bigger leaved and slightly less silvery.
The mamei and plowmanii are really similar. The best way to tell the difference is by looking at the petiole. The mamei has ruffled petioles. The leaves on both are heart shaped but the mamei is slightly rounder.
The mamei aff is a close hybrid of the mamei. Aff means ‘affinity to’. Some hybrids are different to others but in general it is very similar to the mamei but most are bread for more silver on the leaves.
Technically the mamei is crawler like the gloriosum, they are crawling philodendrons, but it does so it a way that it can be staked to a pole, so it often appears as a climbing philodendron. I would describe it as ‘climbing crawler’ (I don’t know if that’s an official term, you heard it here first!).
