Soil Testing & Plant Analysis Lab

Hand full of dirt

You may be interested in our services if you are a:

The vitality of your lawn and garden depend on your soil, but soil properties are often overlooked. Why should you have your soil tested? If you like azaleas but your soil has a high pH (i.e., the soil is basic rather than acidic), you will not have azaleas with stunning spring foliage. If your soil does not have sufficient nutrients, you will not be able to grow a robust garden. Many people have soil samples tested only when plants are in trouble, but the time to test and amend your soil is before problems occur. Soil testing will provide you with the information you need to treat your soil so your plants will flourish.

We test soil, the nutritional status of your plants, and irrigation and pond water.
