Mixing is very important that’s the only way you will get the granular fertilizer the dissolve quickly. Using the paint mixer is an excellent way to mix a large quantities of liquid fertilizer.

You will want to do it multiple time in the one day, maybe 3 to 5 times is great. Do it at different time of the day like morning,noon evening and night. If you can only do it once or twice it will work just keep in mind every granular fertilizer might not dissolve.

You want to use hot tap water for a better outcome. Warm water would be okay, cold water might not be that effective in the granular fertilizer dissolving.

Don’t throw away the particles that did not turn all the way to liquid add some more water to it separately and mix and pour it on your trees or bushes drip line they would love the feeding.

If you use a gallon of milk carton you can just shake it up and pour it over the strainer into a bucket and do the same thing it’s just as effectively than using a paint mixer.
