Mastering pH: Methods and Techniques
Mastering pH in bonsai cultivation is a crucial element to ensure their good health and optimal development. Here are methods and techniques to adjust and control pH, both for watering water and substrate.
A. Adjusting the pH of Watering Water
Use of pH Test Kits: First and foremost, it is important to regularly test the pH of the watering water. Simple and economical test kits are available for this purpose. Acidifying the Water: To lower the pH of the water, one can add acidic substances such as vinegar or citric acid in very measured quantities. Alkalinizing the Water: To increase the pH, the use of baking soda in small quantities can be effective.
B. Adapting the Substrate for pH Control
Choice of Substrate: Some substrates naturally have a more acidic pH (like peat) or more alkaline (like limestone). The initial choice of substrate should therefore be in accordance with the needs of the bonsai species. Substrate Amendments: To adjust the pH of the substrate, amendments can be incorporated. For example, adding lime to increase the pH, or sulfur to decrease it. Substrate Renewal: Periodic repotting with an appropriate pH substrate is crucial, as the pH of the substrate can change over time.
C. Ongoing Monitoring and Adjustments
Regular Monitoring: The pH of the water and substrate must be regularly monitored to ensure it remains within the optimal range for the health of the bonsai. Gradual Adjustments: Any pH change should be done gradually to avoid stressing the tree.
D. Practical Tips
Avoid Extremes: It is important not to make extreme changes in pH, as bonsais prefer stability. Knowledge of Species: Each bonsai species has its own pH requirements. This knowledge is essential for making the right adjustments.
In summary, mastering pH in bonsai cultivation involves a combination of wise substrate choices, adjustments to watering water, and regular monitoring. These practices help maintain a healthy growth environment conducive to the prosperity of bonsais.
