The weather outside may be “frightful” but many of you are starting to thing about Spring Planting Season and our phones are ringing off the hook! Worm Castings “are big right now” with so many people realizing the value of adding worm castings to their soil to help build the soil food web and growing great plants!
We sell to family gardeners and commercial farms. We sell to turf grass growers. We sell to grape farmers, cannabis farms, tomato farms and so much more!
Already this morning we have had two calls from people who are interested in using worm castings to improve their crop quality and yield who were wondering “how much worm casting they needed to buy to treat their soil, so I thought that “worm casting application rates” would make a good topic for today’s post.
There tend to be three ways that people apply worm castings and three types of soil they are trying to amend. The general “rule of thumb for worm casting application rates” is that it should make up 15%-20% of the soil mass. This works out to be about 1/2 lb of worm castings per square foot of soil or 1/2 pound per plant if applying directly in with the root ball when transplanting.
This of course, is for decent quality soil. If the soil is nutrient deficient or if it is heavy clay or very sandy the application rate doubles to about 1lb per square foot or 1 pound per plant at transplanting.
Not interested in doing the worm castings application rate math?? Here is a basic chart to help you:
