Soil pH Testing
Grow healthier plants that are more resistant to disease and insects with a balanced soil.
Before planting trees, shrubs and grass, it’s best to first identify the pH of your soil. pH is a measure of your soil acidity or alkalinity. A proper pH helps plants to absorb, food, water and other trace elements more easily. Your plants will also grow healthier and resist diseases and insects better with the correct soil pH.

What is pH?
pH is a measure of acidity or alkalinity of soil on a scale ranging from 0 to 14; neutral soil has a pH of 7.0.
- Acidic soils have a pH reading below 7.0.
- Most plants prefer slightly acidic soil with a pH of 6.0 to 6.5.
- Most lawns prefer a pH of 6.2 to 6.8 (6.5 is optimum).
- Alkaline soils have a pH reading which measures above 7.0.
- Vines such as honeysuckle, clematis and morning glory prefer alkaline soils.
What is Lime?
Lime, an alkaline substance derived from limestone, is used to raise the pH of soil if it is below a desired range. A proper pH will help trees, shrubs and lawns to better absorb fertilizer, water and nutrients.
