adding worm castings to potting soil...

hey all. just got my LR seeds, so im gonna plant them ASAP. i have a 30 LB bag of worm castings. I want to know what portions i should add the worm castings to my soil. I am using basic scotts potting soil, which looks good just as is, but i want to add the castings to make it more of a thorough soil. im using 1 gallon pots. how much castings should i add to the soil in a 1 gallon pot to make it adequate? i dont want to overdo it, even tho its organic, but i dont want to underdo it either lol. so should i add a handful in each pot? half and half? or what? thanks alot for the help guys.

 

Hey Cheif, this is from an old faq:

Earthworm castings are easy to use. This makes an excellent potting mix or mix to plant in the ground:

25% earthworm castings mixed with 75% soil is a common mix.

On established plants, simply sprinkle about 1/4 inch earthworm castings around the plant that is to be fed and fertilized. Work it into the soil lightly. That\'s it! Be sure the earthworm castings you use are a pure, high-quality earthworm castings.
