Hi,

I would like to know if there are books on using worm castings
only, as a medium?

Probably not but you never can tell what somebody will publish a book about.

Worm castings are generally used as a feriliser and soil conditioner.
Assuming that you had enough to fill a tub or garden bed it wouldn't be such
a good idea to do it. A growing medium should be the right combination (for
the species) of the ability to hold water, air, nutrients and trace
elements, to support the root structure and to support beneficial microbes.
Straight worm castings is likely to fail several of these requirements for
most plants and even if it didn't it would be a profligate consumption of a
valuable resource. Good growing practice is about balance.

i agree with most of David's comments.

i'll add that not all worm castings are
the same. what is the source of worm castings
you might be using?

do you have a specific application in mind?
like a container or a specific plant?

Hi Dave and Songbird,

Commercially bought worm castings - plagron
( Dendrobena Veneta). I have use them as a soil
amendment for a long time, and used them in
soilless potting mixes.

I am thinking of using them the way ordinary compost
is used.

A long time ago I grew a plant in a mix of worm
castings and perlite, and it did spectacularly well,
when fed with high (8.0) pH tap water and worm tea.
My guess is that the pH can get low, or maybe
watering every day flushed the salts out or the
plants liked the high calcium and mg concentration.

It would be nice to know other people's experiences.

I was just wondering whether there is any literature
on using them this way. There are some websites,
but they are very short in description. Like:

http://www.thewormdude.com/worm-blog...worm-castings/

A reason I like worm castings is because I can
basically grow them myself, and keep
foodscraps out of landfills.
