I recently decided to try a Vigoro water soluble general purpose plant food on my numerous hanging baskets and outdoor container plants. Since I'm a retired engineer, I'm not having too much difficulty understanding that the mix ratio is 1 tablespoon of feed to a gallon of water (and yes, that was just a bit of sarcasm...). But there's nothing on the package to indicate how much of the resulting mix to feed each plant. Can anyone provide me with some guidance? Is it a cup per average sized container? Two cups? The entire gallon?

Greetings Cartaphilus…Welcome to the Community!
What a great question! I get asked that very same question in the aisle of my Home Depot garden department. So, you are not the only one trying to decipher, and determine the correct watering proportion for each plant.
It seems to me that you are, a very mathematical person, and would like specific calculations for watering each plant…but sorry to say, the answer is not so cut and (excuse the pun) dry!
Make up your gallon of food and go to each plant, water a little, about 6 ounces, let it absorb, then pour in more till you see it run through the planter holes, then stop. The plant will take up as much food, nutrients, that it needs. If there is a saucer involved, at the bottom of your containers, and there is standing water at the end of this process ….empty it. Most roots don’t like to be in standing water and especially with fertilizer in it. Just remember that your plants don’t need to be feed every time you water; and depending where they are situated…sun, shade, indoors, outdoors the absorption rate will be different.
For annual flowering planters, feed every 7 to 10th day and foliage house plants; feed once a month…I hope that this helps you formulate a schedule and solution for watering. It’s not just math and proportions, it’s watching and nurturing. I am sure your plants will reward you with the care and concern you are showing them…..Let us know how things are growing! BostonRoots
