Plant growth and PH

Plant growth is heavily dependent on the environment in which it is grown, and one of the most important elements of that environment is the soil or growing medium. Whether you are growing plants in coco or soil, a critical factor to keep in mind is the pH level of your soil. In this quick rundown, we will examine the importance of pH in relation to growing plants in coco or soil, and how improper pH levels can impact plant growth.

 Ideal PH

pH plays a vital role in plant growth because it influences nutrient availability, microbial activity, and water uptake. In general, plants require a slightly acidic pH for optimal growth. The ideal pH range for coco coir is between 5.5 and 6.5, while for soil, it is between 6.0 and 7.0. If the pH is too low or too high, then different nutrients may become less available for the plants to use, and this will negatively affect the plant.

 Why is PH important?

One of the most critical aspects of pH in plant growth is its influence on nutrient availability. When the pH level is too high or too low, it can cause some nutrients to be unavailable to the plants, even if they are present in the soil. For example, at a pH level lower than 5.0, essential macronutrients such as phosphorus, calcium, magnesium, and potassium become less available, leading to nutrient deficiencies in the plant. At a pH level above 8.0, iron becomes less soluble and is no longer available for plants to take up, leading to iron chlorosis.

 Microbes And PH

Microbial activity is another crucial function that pH affects. Beneficial microbes help to decompose organic matter, release nutrients, and protect plants from pathogens. However, these microbes have a particular pH range at which they thrive. If the pH falls outside their range, their population will decline, leading to an imbalance that can affect plant health.

The effect of pH on water uptake  

The effect of pH on water uptake cannot be overlooked either. The ability of plants to take up water and nutrients from the soil is influenced by the concentration of ions around the roots, which is determined by pH. If the pH is too high or too low, it can affect the mobility of these ions and make them less available to the plants. This, in turn, leads to slower growth and poor plant performance.

 A pH imbalance can lead to a wide range of plant growth problems

A pH imbalance can lead to a wide range of plant growth problems. Symptoms can vary widely from stunted growth, nutrient deficiencies, leaf yellowing, and even death, depending on the crop and the severity of the pH issue. This illustrates how critical it is to maintain the appropriate pH levels in coco or soil for plant growth.

 pH Too High or Too Low?

The pH level of your growing medium can be monitored using a pH meter or test kit. An application of sulfur or lime can be added to adjust the pH level accordingly. We always use a Bluelab pH pen to test our feed before watering the plants. If you want, you can test the run off water as well. This will help you know what the pH of your medium is as well. A range of products are available in the market to adjust pH levels, particularly coco and soil. We use General Hydroponics pH UP and DOWN Regular testing of the pH level of the growing medium is also critical in ensuring optimal plant growth.

 Conclusion

In conclusion, the proper pH level of the growing medium is crucial for plant growth. It affects nutrient availability, microbial activity, and water uptake, all of which are essential for plant growth. It is essential to ensure that the pH level of the soil or coco medium falls within the correct range to avoid stunted growth, poor yields, or even crop failure. By monitoring and adjusting the pH levels of the growing medium, you can ensure optimal plant growth and overall health.
