The product that you are using as an example isn't really formulated for adding as a drip as the ingredients aren't tremendously water soluable like the Miracle Gro, Peter's, etc., products. This is why they are considered "slow release". What you might want to try with the "Tone" products is to add some to water and let it sit a few days to a week or so (stir it every once in awhile) to make a "tea" and then pour that (along with any undissovled material) onto the plants.

Thanks, Jenny. I will act accordingly.

PS. What great photos on your home page.
