Before Adding Lime

Before embracing the alkaline benefits of lime, it’s crucial to understand your soil’s pH level. Most plants prefer a slightly acidic soil pH range of 5.8 to 6.3. If your soil’s pH level drops below 5.5, the addition of lime becomes a beneficial ally in unlocking your garden’s true potential.


What is lime and why do garden plants need it?

Lime is a substance that is used to raise the pH of soil. Soil pH is a measure of how acidic or alkaline the soil is. Most garden plants prefer a pH between 6.5 and 7.5. If the soil is too acidic, plants may have difficulty absorbing nutrients and may be more susceptible to pests and diseases. Adding lime to the soil can help to raise the pH and make it more suitable for growing plants.

Once you know the pH of your soil, you can use a lime calculator to determine how much lime you need to add to raise the pH to the desired level.

When should I apply lime to my garden?

Lime can be applied to your garden at any time of year, but it is best to apply it in the fall or winter so that it has time to work into the soil before planting season. If you are applying lime in the spring, be sure to apply it at least two weeks before planting.
