Helpful Tips from Lawn Advisors:

What is vermicompost?

Vermicompost is nutrient-rich organic material produced by earthworms. Worms consume organic matter and turn it into "castings" (worm manure). This natural process deactivates harmful bacteria and creates an ideal soil amendment.

What can I use Soil Booster for?

Supports seedling development

Made for turf, fruits, vegetables, cannabis and CEA growing

Aids growth for newly seeded lawn areas

What makes Sunday soil amendment different?

Unlike amendments that only deliver nutrients, Soil Booster focuses on soil health by introducing active microbes that improve microbial balance. This feeds plants and creates a healthier soil ecosystem for long-term plant health.

How to use Soil Booster with other Sunday products?

Apply Soil Booster a few days before using fertilizers for better nutrient absorption. If applying after another product, allow all liquid products to dry completely before application.

Are there any US states where this product is not approved for use?
