One of the main parts of every plant’s care guide is the type of growing medium you need to plant it in; and the same goes for philodendrons.
These climbing and trailing (and sometimes upright) varieties have specific soil needs that you need to meet in order for them to develop properly.
The best soil for philodendron needs to be well-draining and aerated, but retain moisture at the same time. The pH level shouldn’t be too high or low, and it must contain a certain amount of nutrients necessary for plant growth.
To help you out, we decided to discuss these factors in more detail in the following sections, and we’ll also include a couple of recipes for homemade philodendron soil.
And if you don’t have time to mix your own blend, you can find some amazing soil mixes down below!
Finally, if you choose the wrong potting soil for any philodendron variety, the plant will start deteriorating, and we’ll describe the symptoms that may occur in the last section.
Requirements For The Best Philodendron Soil Mix
Philodendron plant care requires using a suitable potting mix for philodendrons, which has to be well-draining, aerated, and loose, but retain some moisture as well.
The pH level should be slightly acidic, and the medium itself has to contain a good amount of nutrients for the plant to thrive.
We’ll discuss these things in more detail and include some ingredients that have draining or moisture-retentive properties.
Drainage & Aeration
Good drainage is crucial for philodendrons, and without it they might become overwatered and get infected with root rot.
The good news is that you can easily avoid this by using loose soils that contain perlite, pumice, or similar materials that don’t retain too much moisture.
These ingredients will allow the excess water to drain quickly and keep your plant’s roots safe.
These materials also encourage aeration, which is essential for healthy philodendron growth. The plant roots need oxygen to thrive, and coarse materials such as perlite, horticultural sand, bark, and grit allow this by making the soil looser.
And if you want to increase drainage even more, use containers with holes in the bottom and terracotta pots (this material allows moisture to evaporate faster).
Philodendrons require ample drainage and aeration, but that doesn’t mean you should use a medium that moisture simply drains through.
Instead, opt for mixes that contain a bit of coco coir, peat moss, humus, or compost since these materials retain moisture and release it whenever your plant needs it.
Furthermore, these ingredients don’t compact the potting medium or mess with needed drainage and aeration (if you use them sparingly).
In general, philodendrons require a slightly acidic growing medium with a pH level between 5.0-6.0.
The pH value of the potting mix is essential for proper growth because your philodendrons won’t be able to absorb moisture and minerals effectively if it’s not suitable.
When buying a store-bought soil mix, you don’t have to pay too much attention to this because the blend already has the suggested pH value.
However, when making your own, you should test it out with a pH meter and adjust it accordingly. Using fertilizers can increase the soil pH level, so you should check it regularly.
For instance, if the pH level is alkaline, you can lower it by using acidifying agents such as lemon juice or vinegar dissolved in water.
Some suggest using peat moss or coffee grounds, but we haven’t had much success with this method as they don’t lower the pH enough.
And if the soil pH level is too acidic (even for your philos), you can add a bit of dolomite lime to increase it a bit.
Philodendrons are fast-growing plants native to tropical rainforests all over the world, and such environments usually have a growing medium incredibly rich in organic matter.
Therefore, always look for ingredients such as compost, humus, earthworm castings, etc., since they can enrich the potting soil mix with necessary nutrients and encourage the fast growth rate of your philodendrons.
Many store-bought blends contain fertilizers, and these are also a great option since your plant will have enough minerals to grow and you won’t have to feed it any time soon.
Homemade Philodendron Potting Mix
Making an aroid potting mix is quite easy, and it works amazingly for all your philodendrons, monsteras, pothos, etc.
We’ve tried many different blends, and although they work fine we wanted something that will really make our philodendrons thrive.
Here’s the philodendron soil mix recipe we found online and can’t get enough of:
We also like to add some worm castings to this mixture just to make it more fertile, as well as a bit of horticultural charcoal.
Instead of coco coir, you can also use sphagnum peat moss as it retains moisture equally well, although we try to use coco products as they’re more environmentally friendly.

Signs Of An Incorrect Soil For Philodendrons
Now you know about the best soil for philodendron, but is it really necessary to get such blends?
Well, these species can tolerate various growing mediums as long as you adjust watering and feeding, but they’ll only thrive in well-draining and loose potting mixes.
And if you keep them in heavy or much too porous soils, you might notice symptoms such as leaf discolorations and wilting.
Yellow leaves are, in most cases, a sign that your plant is overwatered, which is why you should reduce the watering frequency.
However, heavy soils can only aggravate this symptom because they retain too much moisture and don’t allow air circulation around your plant’s roots.
Therefore, opt for a loose substrate which will allow the water to seep through, but still retain some so that you don’t have to irrigate your philodendrons twice a day.
If you notice that your Philodendron ‘Cream Splash’ (or any other philo) is wilting, you should check its growing medium.
Plants usually droop because they are either over or underwatered. Overwatered plants usually result in root rot, and such plants cannot absorb enough moisture and nutrients, leading to wilting.
Underwatered plants simply don’t get enough moisture and they cannot stand upright (the loss of turgor – pressure caused by fluid – causes plants to droop).
Inadequate soil can contribute to these conditions. For instance, porous mediums don’t retain moisture and plants cannot get hydrated enough, while heavy substrates retain too much water, leading to overwatering.
Browning And Dehydration
Brown, wrinkled, and dehydrated foliage is a sure sign that your plant doesn’t get enough moisture, which sometimes has nothing to do with watering frequency.
Porous and sandy soils are terrible at retaining moisture, which is why you shouldn’t use that sort of substrate with philodendrons. If you do, you should water them much more frequently.
The good news is that you don’t have to throw that potting mix away; simply add some coir and vermiculite, and you’ll turn into a perfect aroid blend.
The best soil for philodendron is well-draining, aerated, retains a bit of moisture, has a slightly acidic pH level, and is rich in organic matter.
You can find store-bought products that meet these requirements, or you can make your own blend.
Technically, philodendrons will tolerate heavier or more porous substrates, but you’ll have to adjust watering frequency accordingly.
If you don’t do that, you’ll find yourself dealing with dehydrated plants, discolored foliage, and droopy philodendrons.
Hopefully, it won’t come to that!
Until next time!
