Worm castings are a very good fertiliser and a good source of nutrition for anything that grows. You could use it 'as is', or soak it for a couple of days and aerate it to introduce oxygen and make a tea with it. If you do, then use it fresh within in a day or two or it will turn anaerobic.

Thanks Myron, I found a 'recipe' for wormcast tea but it seemed like a lot of work involving molasses and running airlines from a pump. It was obviously intended for people who have proper wormeries and, therefore, lots of wormcast.

I take my tea without sugar so I think that the molasses is optional ;o)

You might be right about the aerating thing but as you suggested, doing it this way is probably making it on a semi-commercial scale. I just thought that rather than scattering it on the soil, it might be better to dissolve it in water, leave it a day or so and use is as a liquid feed. It would be a lot easier to apply and get right down to where the roots are quicker.
