Monstera Require Good Aeration In Their Soil

Monstera needs to be grown in a well-aerated soil type. If the soil is too compact, it can prevent the plants’ roots from developing correctly. Monstera roots need oxygen to stay healthy; if they are too compacted, they will not get the oxygen they need to survive.

Compacted soils can also lead to water retention in the ground, and with decreased levels of oxygen in the soil, this can lead to root rot.

Decreased oxygen levels and excess moisture create room for fungi to move in and start to feed on your Monsteras roots. Often in these situations, if you do not catch the infection in time, it can lead to the death of your plant.

Monstera Require Nutrient-Rich Soils

Your plant will acquire the nutrients necessary for optimal growth from the soil through its root system.

Monsteras’ natural habitat is the forest floor in tropical Central America. In these environments, the soils have the added nutrients from animal droppings, biodegrading plants, and aeration done by earthworms.

As most soils will not have these added benefits that forest floors have, they need to be supplemented through their soil mix and, in most cases, with fertilizers too. Using compost and peat moss in your soil mix can give your soil added nutrients.

Monstera Require Slightly Acidic To Neutral Soils

Like many other household plants, Monstera prefers slightly acidic soils. Luckily, most of the ingredients used in potting mixes are somewhat acidic.

pH levels go from 0 – 14, with seven being neutral, anything below seven is considered acidic, and anything above is alkaline. Monstera prefers soil that measures between 5.0 and 6.8.

Not all potting mixes will have a pH indication on their packaging. One way to combat this is to keep in mind that coco coir has a pH level of 5.2 – 6.8, peat moss has a pH level of around 4.5, and pine needles have a pH level of about 5.0. So if your mix includes any or all of these, you should know that it is slightly acidic.
