Organic Container Gardening

[CarolynPhillips]

How do you grow organic in containers?
I keep reading that you cannot amend potting soil with organic fertilizer because it leaches out quicker than ground surface organic gardening.
BUt so does chemical fertilizers. When using chemical fertilizers, you have to add the fertilizer on a weekly basis.
I am assuming you would have to do the same with homemade organic fertilizer mixture but my problems is .......I can't see that working right.

Here is a homemade organic fertilizer recipe.

Organic Fertilizer Mix= measurements with Quart size container
4 quarts Cotton Seed Meal (or any seed meal)
1 /3 quart Agricultural Lime
1/3 quart Dolomite Lime
1/3 quart Gypsum (or double Ag Lime)
1 quart Bone Meal or Rock Phosphate
1 quart Rock Dust or Kelp Meal
Mix in 5 gallon bucket.
Spread 1/4 inch of compost or manure over grow beds or row for light to medium feeders. Spread 1/2 inch of compost or manure over grow beds or row for heavy feeders.
Use 4 to 6 quarts of Organic Fertilizer Mix per 100 square feet of grow bed or row and mix into soil 4 to 6 inches deep
You only have to apply this once per year. (Spring)
In addition to the Organic Fertilizer Mix,
You can apply 4 to 6 quarts of Cotton Seed Meal ( or other seed meal) per 100 sq. ft of grow bed around medium to heavy feeders every 3 to 4 weeks or as needed after initial organic fertilizer has been applied.. Scratch into surface of soil.
By my calculations per square foot, you would need about 4.5 tablespoons per square foot. This calculation should also work with container gardening. Even a round 12 inch containers would only need 4.5 tablespoons. An Earthbox 1ft x 2ft, for example , would need 9 tablespoons.

Would I be wasting my money and time by adding this to a 5 gallon pot that is watered on a daily basis?
Would it work in SWC such as the earthbox?

I haven't finished searching the net for answers but it just doesn't seem right that we would have to buy pre-mixed organic fertilizers in small quantities at expenses prices.
there has to be a way to do it homemade.
