How to Prepare Potting Soil for Planting?

So, you have finally chosen the right potting soil for your plants? Well, that is indeed the easier option. However, some gardeners may also want to prepare potting soil themselves. So, in this section, let us get into the details of preparation. 

Ideally, the right potting soil for indoor plants would deliver the right pH and consistent nutrients. Though, this will also depend highly on your plant’s requirements. 

Note that to make your potting soil, you will have to put some extra effort. In short, the simplest recipe for this includes 60% soil-building material and 40% aeration materials along with nutrients. 

For the soil building material, you can use coco-coir or peat moss. These are the best absorbent, and quite lightweight. However, note that both these soil materials will come in a compressed form. So, after opening the pack, you must let them soak some water. For that, just add them to a bowl containing water, and let them expand. 

When it comes to the aeration material and nutrients, perlite is perhaps the best option. This material keeps the soil open and airy and assists in the drainage. Typically, indoor potting soils contain around 30% perlite. This helps the plants in developing strong roots.

With that, you may as well want to add some worm castings. These materials are odor-free and very safe to use. Usually, you can find them inside all organic potting soil for indoor plants. But if you are preparing potting soil yourself, you can add 10% of worm castings by the total weight to give it an organic touch. 

Frequently Asked Questions 

Can I adjust the pH of the soil myself?

Can I use 100% organic material?

Can I change the potting soil?

If you are planning to switch to a different brand, then a good way is to first create a blend of the old and new brands. Do not just top off the new indoor potting soil. If there are different layers of soil in your pot, then your plant could get negatively affected.
