Due to the composition of the product, sometimes there is some settlement in the bottom of the container. Shake well before using and if a clog develops, remove the sprayer and soak it in warm water for five minutes. You can also use a standard dial in sprayer with a setting of 1 oz.

It is best to use HastaGro Lawn when it will not be washed off the blades/leaves. For Soil Activator and Medina Plus, it is necessary to water the product in after application, so right before a rain is a great time to apply.
HastaGro Lawn needs to sit on the grass for 24 hours after application. It is best to put it on when you will not need to mow or water in that time frame.
