Hey Troy!
Building on what Lo is saying here, your annual Thrive kit is a specially portioned version of our microalgae that breaks up lawn applications for the entire year (spring, summer and fall) into correctly sized bottles for your lawn size (unless we send the wrong shipment of course 
). Microalgae is good for many types of plants as it’s retoring the soil, and healthy soil is the foundation for healthy plants. So, you can definitely use it on other plants, and we can assist with instructions to do so, but keep in mind you’ll have less for your lawn.
