I initially filled them with Kellogg organic soil mix - in bags. The first year they produced beautifully. This spring/summer - hardly a thing. I added only a small amount of cow manure to them - but I did add fertilizer. Don't know where I went wrong.
For one of the 4 x 6 beds, Went to local nursery and she sold me a bag of "soil" intended for roses and said it's great for veggies (so I didn't worry about organic, I just want to produce something at this point LOL). I also put a bag of the manure in that bed, and the plants are doing great. But before I proceed to the additional beds really want to understand what I should do.
Now I'm planting fall garden. I tilled them up with a shovel and added a large bag of composted organic cow manure to each 4 x 6 bed (which is about 10-12" deep). Do I need to add anything else? Do I need to fertilize in addition to the manure. Do I really need a bag of that rose "soil" which also has fertilizer in it ? Clearly I am a novice when I comes to growing my own food - especially in raised beds. I've done some plants in the greenhouse and they did well, but out of 20 tomato plants this year I probably got 5 tomatoes.

Same thing with the green beans.
This fall I am planting lots of leafy greens (bok coy, chart, kale), radishes, carrots.
Any suggestions will be greatly appreciated.
