I have an automatic sprinkler system. I use Miracle Grow sprayer once in a
while to fertilize.

Has anyone hooked up one of these fertilizer mixers inline with their
sprinklers?

I think it would do fine for the flowers, giving them a weak flow of
fertilizer, and feeding them more steadily than my once in a while when I
remember it and get around to it.

For the grass, could I use Miracle Grow, or would I have to use regular lawn
fertilizer granules?

I am repairing the sprinklers at my house, so, this qualifies as home
repair, right?
