Frequently Asked Questions

What’s the ideal pH level for the typical backyard garden?

Since most plants do their best in a 6.0 to 7.0 pH range, a pH of 6.5 is a pretty safe bet for typical home gardens. There are some plants that thrive under more alkaline conditions, while others prefer a higher acidic range. Your best bet? Take a look at what you’re wanting to plant and find out their preferred soil range. Since most will be around 6.5, start there. For the plants that prefer either more alkalinity or more acidity, adjust in those specific spots accordingly.

How can you adjust the pH of your soil?

If you need soil that’s more alkaline, the most common practice is to apply a material that contains lime, such as ground agricultural limestone. Other quick solutions for altering pH soil levels include baking soda and other home DIY solutions. While these don’t permanently alter the soil balance, some folks swear by them.

To really work your soil, it’s best to use high-quality compost at the end of season and work it into your soil. With time, that rich organic matter will gradually decompose, creating an optimal pH balance in the soil that will be ready for planting once the growing season starts. Other easy solutions include coffee grounds, pine needles, peat moss, and mulch. Depending on the results you want, there’s a wide range of pretty easy steps to take for quality results.
