Worm Castings Extract

Aerated Castings Tea:

You may have heard of “Aerated Castings Tea”.

This is where a small amount of worm castings are placed in a 5 gallon bucket of water and aerated with an air pump (or even by hand).

The resulting liquid “tea” can be diluted with up to 5 parts water before applying as a ground drench.

This is a GREAT way to make a little worm castings go a long, long, LONG way.

But, another way you can make a little worm castings go further – and make it easy to apply – is by making a worm castings EXTRACT.

You can make an “extract” by:

Place some VC (about 2 to 4 cups) into a 5 gallon bucket of water (rain water, or water left to de-chlorinate overnight, is best)
Stir it around for a couple of minutes.
Apply it immediately as a soil drench, not using it on the leaves of edible plants (see the cautions on the “How To Use Worm Castings” page linked below.)

Apply it directly from the bucket. If you are using a watering can, use it without the rose on the spout.

Water it in well too.

Optionally, you can place the VC in a stocking or paint strainer, or use a sieve.
This may help remove seeds, cocoons or worms from the VC.

After use, the contents of the sieve can be placed back in the worm farm after making the extract – or into another plant etc.
