Top 10 Acid Loving Indoor Plants

Indoor plants not only enhance indoor beauty but also make the indoors healthier and happier by reducing stress, enhancing moods, and increasing productivity. Furthermore, it also has health benefits as it reduces the toxins and pollutants from the indoor space. Growing plants requires a lot of patience and effort as various plants pose a different challenge depending on their soil requirements, sunlight, and so on.

Most plants generally require an alkaline or neutral soil to thrive, whereas few others require acidic soil to grow and bloom. The plants that require soil of pH less than 6.5 or around 5.5, i.e., acidic soil, are termed as acid-loving plants. The acidity of the soil increases due to the breakdown of plant residues and organic matter producing organic acids, thus raising the soil's acidity. Acid-loving plants require acidic soil to thrive as the soil's lower pH allows the plants to take in the nutrients and develop.

Loving Indoor Plants

Conclusion on Indoor Plant

To cater to acid-loving household plants, neutral, alkaline, or less acidic soil can be enhanced into more acidic or highly acidic as needed by adding external products that reduce soil's pH, such as fertilizers. Fertilizers change the soil's pH, i.e., from alkaline to acidic and from slightly acidic to highly acidic depending on acid-loving plants' requirement. Acidifying fertilizers or nitrogen fertilizers can be added to soil to reduce its pH for acid-loving household plants to develop and bloom. Fertilizers enable acid-loving plants to even flourish in alkaline soils to soak up the nutrients that would only be present in acidic soil.

In the presence of acidic soil, acid-loving plants can be grown in place of typical plants that require neutral or alkaline soil to grow. Acidity or pH of the soil can be tested using a soil testing kit, and plants can be grown as per the soil's pH.
