Worm castings are quite simply the most powerful and incredible all-purpose organic fertilizer that you will ever use. They are simple to use, 100 percent safe and natural, and best of all, they power plants beyond belief.
This is our fourth season of utilizing worm castings at the farm. We first began to use them in our seed starting mix in the spring of 2014.
That year, we mixed in a cup of castings along with the regular ingredients we use to make our homemade potting soil – compost, perlite and pulverized top soil.
The results were astounding. We only used the mix in half of our seed trays that year as a trial. 6 weeks later, there was simply no comparison.
