Using Wormcastings as a fertilizer.


Grandpa’s Natural Fertilizer is 100% sifted worm castings.

Worm Castings contain a highly active biological mixture of microbes, bacteria, enzymes, Nitrogen, Phosphorus, Potassium and other trace minerals.  The castings are rich in water-soluble plant nutrients, and contain more than 50% more humus than what is normally found in topsoil. Helping your soil retain more moisture, for longer periods.

Worm castings stimulate plant growth more than any other natural product on the market. Unlike animal manure, fish fertilizers, or artificial fertilizers it is absorbed easily and immediately by plants, and will never burn them.

Also, while many products on the market boast “casting mix”; most are only 1-3%,  worm castings.  And very few of these will actually qualify how much worm castings are contained in them.  But Ohio State research has shown that the optimum ratio for worm castings to native soil is 10-20%.  Our castings are double sifted down to 1/8″ screen for 100% worm castings, so you can mix your own soil.   A single 50lb bag then can make upto 500 lbs of rich 10% casting soil, instead of weak 1-3%.

How to use Worm Castings:

For Germination:

Use 30% Worm Castings with sand as a germination mixture. It will ensure lush growth for about three months, without you having to add any other plant food.

As a Soil Conditioner

On tilled barren soil, add a layer of Worm Castings and give it some water, you will be surprised at the growth of your first season’s plants.

As a Fertilizer

Sprinkle Worm Castings around the base of plants or lightly dig it in, and then add water. They can also be sprinkled on a large scale with a spreader. Remember: you do not ever need to be concerned with burning your plants with worm castings.  They are pH neutral and will not harm even the finest root systems.

Here is a Youtube example of fertilizing your lawn with worm castings:

As a Liquid Fertilizer

Mix with water. Use 1 cup Worm Castings for every gallon of water, stir in 1 Tbs of unsulfured molasses.   Aerate overnight with a small fish tank aeration pump; it will be ready for use in 24 to 48 hours.  Or, without aeration, simply let it stand and wait 1 week. The water soluble microbes and bacteria will multiply rapidly throughout the sugar enriched water.  This liquid mixture can be used as an excellent fertilizer or leaf foliate spray.

There are allot of Youtube videos out there showing you how to make Worm Tea.   For best results, essentially all you need are 4 items:

1) Worm Castings

2) Non-sulfured Molasses (syrup or dry)

3) An Aerator (small fish tank type)

4) And a Bucket

Here is a link to one with a couple more ingredients, but the process and idea are the same.
