How to Raise pH in Potted Plants

Most plants require a specific soil pH level in order to thrive. If you find that your potted plants are struggling to grow, the soil pH could be the culprit. Here are some tips on how to raise pH in potted plants:

1. Test the Soil pH

Before making any adjustments to the soil pH, it's important to first determine what the current pH level is. You can do this using a soil pH testing kit or by sending a soil sample to a lab for analysis. Once you know what the current pH level is, you can then determine how much adjustment is necessary.

2. Add Lime

If the soil pH is too low (acidic), adding lime can raise the pH level. Lime is a natural mineral that is safe for most plants. However, it's important to apply it correctly. Mix the lime into the soil thoroughly and follow the manufacturer's instructions for how much to apply based on the size of your pot.

3. Use a pH-Adjusting Fertilizer

Another option for raising soil pH is to use a pH-adjusting fertilizer. These fertilizers contain specific ingredients that help to raise the pH level of the soil. Follow the manufacturer's instructions for how much and how often to apply the fertilizer.

4. Use Dolomite Lime

If you are looking for a more natural way to raise the pH level of your soil, using dolomite lime can be a great option. Dolomite lime is a type of lime that is rich in magnesium and calcium. These minerals help to balance the soil pH and improve soil health. Simply mix the dolomite lime into the soil before planting.

5. Avoid Overwatering

Overwatering your potted plants can cause the soil pH to become more acidic. This is because excess water can leach out nutrients, including calcium and magnesium, which are important for maintaining a balanced soil pH. Be sure to water your plants only when necessary and avoid letting water sit in the saucer underneath the pot.

6. Monitor Soil pH

After making any adjustments to the soil pH, it's important to continue monitoring it to ensure that it stays within the ideal range for your plants. You can do this by regularly testing the soil pH and making adjustments as necessary. Keeping a close eye on the soil pH will help ensure that your plants are healthy and thriving.

Raising the pH level of soil in potted plants can take some trial and error, but by following these tips, you can create the ideal growing environment for your plants.
