Highest Organic NPK rating ?

[PaulZone8b]

I have tried to stay with all organic and no synthetic fertilizers for a couple years now and just bought some onions from Dixondale. They say to put a 10-20-10 fertilizer and no organic fertilizer has that high a numbers. I am making my own compost and adding that and castings, but I dont think that is enough. Previous attempts at onions have been very small and not the big bulbs that others get....probably with "Miracle Grow" which I refuse to use that junk.

I agree with you that Miracle Grow is junk. I use fish emulsion at 5-1-1 on my onions. They like the early Nitrogen and the water helps growth as well...



and get a lot of 6-inch diameter bulbs most years. But that isn't all that goes into growing big bulbs. They need a long growing season...I start from seed in Oct 15 and harvest the following late May early June. During the growing season, especially after they start bulbing in earnest in March, I like to loosen the dirt around the bulb and pull it back some to just where the roots are only covered, nut buried. Tedious, but helps grow out big bulbs. Any/all that bolt to seed become green onions for the table.

Thanks Meadowlark. Then I guess I wont worry too much about the higher NPK numbers (20s) Yikes thats a number from MGrow and the like. Steroids. I have fish emulsion and Agrothrive General Liquid Fert (3-3-2) and use finished compost and castings too. Bone Meal is a high root aid and Blood Meal for the Nitrogen, so I will add that into the mix as well. OK, I will get these onion starts in the ground today with the fertilizer furrow in the middle of the 2 rows of onions as they suggested.
