In my experience, the best potting soil for indoor plants is a balanced mix of organic and inorganic matter. The organic part is crucial as it supplies the necessary nutrients that my plants crave. Meanwhile, the inorganic portion ensures proper drainage and aeration, which is just as essential for their health.

The initial step I take in assessing if my soil is apt for plant growth is to check its pH level. pH essentially measures how acidic or alkaline the soil is. A pH of 7 is considered neutral. Below 7, the soil is acidic, and above 7, it’s alkaline. In my garden, I’ve found that most plants favor a slightly acidic environment, with a pH range of 6.0 to 7.0.

To determine the pH of my soil, I use a soil test kit, easily available at most garden centers. It’s quite straightforward to use; I just follow the kit’s instructions.

Now, plants primarily need three nutrients: nitrogen (N), phosphorus (P), and potassium (K), collectively known as NPK. Nitrogen is vital for leaf development, phosphorus for roots, and potassium for flowers and fruits.

For the most accurate insight into a soil’s nutrient levels, get it tested by a professional lab. However, I usually use home soil test kits, which are pretty user-friendly.

Once I have the pH and nutrient information, I make any necessary adjustments. If my soil is too acidic, I add lime to raise the pH. Conversely, if it’s too alkaline, I use sulfur to lower it. If it’s lacking in nutrients, I opt for fertilizer.

Regular soil testing is a must when I’m adding a soil amendment. It’s a key practice to ensure my plants are healthy and receiving all the nutrients they require. This approach has always helped me maintain a vibrant and thriving indoor garden.
