SECRET Fertilizer :) My 'fertilizing cocktail' consists of mixing 1/2 bottle of cheap beer, 1 tablespoon of Epson salts, and 2 tablespoons of fish emulsion in a watering can (1-2 gallons). I do this to ALL my vegetable, flowers, and indoor plants. You will definitely notice the difference in a few weeks! Don't waste too much money on the beer. Cheapest still works great -- plants aren't picky!
Crushed egg shells ... One pinner says: Each time you crack an egg open, instead of tossing the shell into the trash, drop it into an open container that you keep in the fridge. (I've always saved my shells, but my friend Susan suggested keeping them in the fridge - works beautifully.) When the container is full, crush the shells into small bits and sprinkle them around the base of your plants. The sharp egg shells will deter slugs, snails, and other bugs from nibbling on your garden.
