What you'll need

What is the best soil for Monstera?

There are a few key properties to look for in the best soil for Monstera plants. In a nutshell, you'll need a nutrient-rich mix that retains moisture but doesn't hold onto enough water to drench your plants.

'The best potting soil for Monstera plants is well-draining, rich in organic matter, and has a good balance of moisture retention and aeration,' says Jo Lambell, founder of Beards & Daisies and author of The Unkillables.

The reason behind this? You'll want to match the potting soil with the plant's natural environment as closely as possible. 'Monstera plants thrive in a mix that mimics their natural habitat, which is the tropical forest floor where the soil is loose and full of decomposing plant material,' Jo explains.

This sparked the idea for a business that makes plant delivery more accessible.

There are also a few ways you can enrich the soil with organic matter. 'Adding compost and worm castings to the soil mix provides essential nutrients for healthy growth,' Elise adds.

FAQs

Do Monstera plants like deep pots?

The short answer is yes – your Monstera plant will appreciate as much room as you can spare.

'They do well in deep pots because they have a substantial root system that benefits from the extra space to grow,' says Jo from Beards & Daisies. 'Deep pots also help to accommodate the plant's aerial roots, which can extend into the soil. However, make sure the pot has good drainage to prevent water from accumulating at the bottom.'

What is the best potting mix for a Monstera cutting?

We've covered the best soil for mature Monstera plants, but what if you've just learned how to propagate Monstera and you're trying to grow new plants from cuttings?

Similar principles apply, but you'll want to aim for extra aeration. 'For Monstera cuttings, it is essential to have a lightweight mix that supports root development,' says Elise from Prestige Flowers. 'I’d suggest two parts perlite or pumice as the aeration qualities would help prevent root rot.

'Then, one part of peat moss or coco coir would provide necessary moisture retention. A little bit of charcoal can keep the mix fresh and prevent fungal growth.'

Remember to keep your potting mix moist to help the cuttings root, but to avoid root rot, make sure you aren't waterlogging them.

Can I use multi-purpose compost for Monstera?

What if you've got some spare multi-purpose compost to hand?

'While you can use multi-purpose compost, it’s not ideal on its own because it might retain too much moisture and become compacted, leading to poor aeration and potential root rot,' advises Jo from Beards & Daisies. 'If you choose to use multi-purpose compost, it’s best to mix it with perlite, orchid bark, or coarse sand to improve drainage and aeration.'

Checking that your potting mix has plenty of drainage, aeration and organic matter will ensure you have the best soil for Monstera, spelling healthy growth for your plants.
