Potting Soil for Indoor Plants

Potting Soil for Indoor Plants

A few things to consider when choosing soil for your indoor plants...

The vast majority of plants need soil in order to live. It’s where their roots grow, and it’s how they access water. For indoor plants specifically, it’s also where they get their food – plants living outside have access to decomposing matter, bacteria, worms and other nutrient sources, whereas indoor plants only have access to what’s in the pot or what you spray them with.

When choosing the soil for indoor plants, it’s pretty normal to feel a tad overwhelmed with all the options, so let’s break it down a little, and chat about what soil we recommend.

 

Did you know…

That the majority of “soil” you see in indoor pots is not actually soil at all. It’s quite different from the stuff that plants growing out in the wild live in. It’s usually a man-made, soil-less mix comprised of things like peat moss, perlite, compost, manure, fertiliser, and a bunch of other stuff. Sounds weird, but it’s actually a superior environment for indoor plants to grow in and is formulated to keep them healthy and happy.

 

Pro tip to choosing the best mix

When choosing soil for your plants, premium is better. After all, this is the environment they’re going to live in for the next 12 to 18 months (before you repot them). In Australia, finding a premium mix is easy – simply look out for a bag of soil or potting mix with red ticks on the bag. These ticks mean that the mix meets certain quality standards, are better at holding on to water, and contain fertiliser, amongst other factors.

Potting mix recipes

Whilst premium general purpose mix is good on its own, it can be useful to add soil amendments such as perlite or coir to improve drainage. Well-aerated soil that drains easily will help avoid waterlogged soil and even root rot. Here’s a few different mixes/recipes that we recommend:

 

  1. A great basic mix is simply adding perlite to premium potting mix with 40% perlite and 60% premium soil. This is suitable for many standard indoor plants such as Calatheas, Monsteras, Dieffenbachia, Aglaonemas, Alocasias, Spider Plants, Devils Ivy, and more.
  2. Our go to recipe to prime plant health is 30% orchid bark, 30% perlite, 20% premium potting mix and 10% charcoal. This is suitable for the same standard indoor plants as above, but is a richer mix
  3. 30% orchid bark, 30% perlite and 40% premium potting mix is another good option for many common houseplants such as Peperomias, Syngoniums, and Alocasias
  4. For plants that like to stay dry, we recommend 60% premium potting mix and 40% perlite. This works nicely for plants with delicate/short roots or roots that don’t like to be wet such as Snake Plants, String of Pearls, Chain of Hearts, Cacti and Succulents
