fertilizer how and when
 

I am interested in how folks fertilize their herbs and vegetables. I have potted herbs - basil, rosemary, mint, chives, dill, cat-mint, as well as lettuce, tomatoes, bell pepper, chilli, spinach...

I would like to know how to fertilize and how often.

I'm thinking of using household ingredients: egg shells for calcium, aquarium water for nitrogen, urine, milk and coffee grounds are all other ingredients that I have readily on hand.

However, I'm not sure how often I should fertilize and in what combination. Obviously some plants like the tomatoes will need more, than say the rosemary. Difficult!

I cannot make a compost heap or have a wormery where I live, so I've gotta do the best I can with what's at hand, and I want to keep it organic.

Any advice would be much appreciated.

In general, herbs you grow in containers will need more fertilization because they have no other way to get additional nutrients once they've used up what's in the pot. But first things first, make sure you grow potted herbs in a light, well-drained, premium potting "mix "(not cheap dollar-a-bag potting "soils"). Too, make sure the pot has drainage holes and, if there are none, drill one or two.

For efficiency, your potted herbs can be fed every two weeks with a liquid fertilize such as fish emulsion, mixed at full strength as suggested on the product label. Organic nutrients are recommended over synthetic, because synthetic fertilizers usually contain a lot of salts, and this can build up over time in potting soil.
