A Simple Fertilizer Question

[lapk78]

TLDR: Using Tomato Miracle-Gro or Texas Tomato Food at 1 tbsp per gallon of water, how much of this fertilizer water should I give to each plant?

I'll preface this question by saying this is my first year growing in raised beds. (I have only used EarthTainers up until now). I have two 4'x4'x15" raised beds, each with an indeterminate cherry planted in each corner (well, 1 is a beefsteak I'm letting have 4 leads...). So 4 plants per bed. I'm really only pruning the cherries enough to allow for air flow- not limiting the number of stems/leads.

I mixed in the recommended amount of Garden Tone at plant out in late February, but now want to start feeding with something water soluble. I have the Tomato-specific Miracle-Gro (the red stuff) and waiting on a delivery of Urban Farm's Texas Tomato Food, which I have heard really good things about.

Both of these recommend a concentration of 1 Tablespoon per gallon of water. And I am considering alternating between the two, feeding once every 7 days. So MG week 1, TTF week 2, MG week 3, TTF week 4, etc...

My Question: How much of this fertilizer water should I give to each plant? A full gallon? Half a gallon? Enough to saturate the entire bed? I never really had to think about this in the past with the self watering containers.

Thanks for any input!
