You don't add advanced nutrients to the pre-existing soil, you water with. I know i need dolmite lime and i plan on bringing in worm casting and a higher P guano but is there anything im missing? Also, for a 6*6*3 foot hole how much dolmite do i put down? Do i just generously cover the soil and then mix it in well. Some sort of answer would be helpful. I've quickly realized that this is one of the least active site out there.
