Almost any type of soil would ideally include mosses. Mosses are things that add to the soils’ pH levels and, sometimes, acidity, too. An orchid soil is one of the soils that have mosses. Peat mosses and sphagnum mosses are two types of mosses that are common for orchid soil. 

Peat mosses are common for Phalaenopsis orchids, the types of orchids in which the alternate name is the moth orchid. Sphagnum mosses, on the other side, are frequently present in smaller-sized orchids in small pots. An orchid soil can only have one of the mosses.

Other than containing either one peat or sphagnum mosses, a commercial orchid soil mixture will also consist of perlites to stabilize the pH levels. Perlites belong to the inorganic elements in the orchid soil. Other inorganic elements that can be present are the Leca clay pebbles that are often on the bottom part of the plant.

Apart from the mosses and perlites, every orchid soils also include the tree bark to add to the textures. Fir trees are the types of trees that barks are often found in orchid soils. Fir tree barks have three grades: Fine, medium, and coarse. You can adjust the gradings according to the plants you want to grow.

Is orchid soil good for bonsai trees

Most of the time, we know that orchid soils are perfect for any orchid type. Yet, here, the question is, are we sure we’re on the right track if we choose orchid soils to grow bonsai trees?

Some components need regular repotting, while you should mix the other materials with other well-draining soils. Additionally, always make sure you’re using anodized aluminum wires if you plan to grow your bonsai trees using an orchid soil mixture.

Bonsai Soil Basics

No. Orchid and bonsai soils have different ideal mixtures even though both types of soils can contain peat mosses. 

For example, Akadama, the Japanese granular clay-like mineral, is the mixture component that you can only find in bonsai soils. Another example is the Sequoia bark for orchid soils that are in some of the world’s Orchid Societies.

The pH levels are also different for both types of soils. Bonsai soils’ ideal pH is between 6.5-7.5, which is higher than the average orchid soils’ pH of approximately 5.5-6.5. On the other side, orchid soils require more lightings than bonsai soils so you can grow the plants.

When mixed well with other ingredients or adequate water levels, the low pH levels of orchid soils can go higher, so they can balance the whole anatomies of the bonsai trees. The trees’ roots are the parts that can drain the water more than the other parts.

There are many ways you can use to water your bonsai trees if you use orchid soil.

Compared to other “exclusive” types of soils, such as bonsai soils, orchid soils are cheaper. Their overall economical prices are coupled with the beautiful-looking bonsai plants that usually go well with the orchid soils. No doubt any combinations between orchid soils and bonsai trees are the most popular.

Cons of using orchid soil for bonsai trees

Orchid soils are among the neediest soil types when it comes to lighting adjustments. They don’t only require more degrees of lightings compared to other types of soils. If you use orchid soils to plant your bonsai trees, be prepared to adjust the lighting mediums and the lighting exposures.

LED or fluorescent lamps are the most popular mediums for shining bonsai trees under orchid soil. However, paying extra attention to the types of lamps is highly important. Failing to do so can affect your bonsai’s appearance and, eventually, the bonsai’s health and overall well-being.

If your bonsai trees’ leaves are blackened, then, those are yet other red-flag signs that you should pay attention to. It can be because you overfertilize your bonsai trees. Bonsai trees growing on orchid soils don’t need that many fertilizers.

In some places, orchid soils don’t perform in their best states when coupled with bonsai trees. Some of those places are anywhere near radiators, floor heaters, or vents. In addition, you can’t freeze the bonsai trees that grow above the orchid soils as there are chances that they can look dull.

Starting from there on, we can modify the mixtures while not losing the central characteristics they have.

For example, we can use gravel or lava rocks as substitutes for fir tree barks. Or, we can use coconut husk chips for our soil mixtures to expose more of the root parts to the air, so they can “breathe” inside.
