Worm castings are a great addition to your seed starting mix for planting seeds of all kinds that will allow for strong healthy plants that will sprout and grow amazingly fast.

No more leggy yellow looking plants when this seed starting method is used correctly.

First off, we want to start out with good quality seeds to insure germination and continued growth throughout the plants life.

Don’t use cheap seeds because you may wind up with amazing looking plants that produce very little yield.

Germinate only the best seeds to get the best results from your efforts.

Mix about 25% worm castings into a quality seed starting mix in a separate container and mix using your hands until it has no clumps and becomes a fine medium.

It is not recommended to use potting soil because it does not work as well in my experience.

There is no need in using more than 25%, through my testing I found it will make no difference using more.

Place your seed starting  mix into your desired seed starting containers and soak with water several times until the water is running out the bottom of the cells.

Let drain until water stops and plant your seeds as directions on the package describe covering your seeds with a pinch of the dry starting mix until the seed is covered. Use a spray bottle to wet the dry starter mix you just added and you are set.

Place your seed starting trays under grow lights after about 2 days

for most plants starts and your will see them coming through about the third day. (Some plants have longer germination rates check the packet).

The main concept here is to get the plants under the lights as soon as they break the surface to prevent legginess.

I have had plant seedlings that grew an inch overnight because I wasn’t paying attention.

Keep the the seedlings as close to your grow lights as possible without touching the bulbs. ( within a half inch is good).

Maintain this practice until you see the first set of true leaves appear.

No watering will be needed for at least a week or until the cells dry out a bit. 

This will let the plant starts develop a strong root system by reaching out for the moisture.

The worm castings have a great water retaining capability and do not require as much watering.

Bottom water only when watering is needed this reduces any chance of fungus growing in the cells. It is always better to be a little damp than wet.

How To Use Worm Castings to make worm castings tea

Just get yourself a five gallon bucket and add a few hand fulls of castings and add water.

Let the batch steep overnight stirring it several times during the process to keep air in the mix which allows more microbes to develop.

  The next morning stir again and  water your garden plants with it. This process will add microbes to your garden soil to help keep the biology alive  that in turn helps feed your plants..

Give it a day or two and see the effects, you will be amazed!

There are many worm tea recipes online that you can use as you wish but it is not necessary to brew worm tea.

Another way to use worm tea is ti spray it directly on the plants leaves.We use a slightly different approach here which may require a bit more stirring.

Place the castings in a cache like (nylons or an old sock or some kind of bag ) so the they stay contained during the steeping process.

This method keeps the solution clean so you can use the tea in a spray bottle or pressurized sprayer to apply directly on your garden plants leaves to add some protection against the garden insect pests while feeding the plants at the same time.

The plants will love this and respond quickly to it.

This process is best if applied late in the evening as the sun goes down to prevent sun burn damage to the plants while letting the tea dry slowly allowing the plants feed through their leaves while  absorbing the tea.

You can also use this process of spraying the tea on your house plants as well they will also love it.


How To Use Worm Castings To Feed Your Plants

Feeding your plants once in a while is also a good use for the castings. Worm castings tea like we mentioned above is a great food source on a regular bases for all plants while making your supply of castings stretch much further.

Working the castings into your soil around your outdoor plants during the growing season is also a good practice.

This is not only to help feed the plants but also creates new biology around your plant roots for stability in growth.

Work slightly deep (about 3 or 4 inches) into the soil and water in well about once a month.

Add castings to the base soil and lightly work in to the surface of your house plants and water in well to feed them also.


How To Use Worm Castings On Your Lawn

Many are reporting improvement in lawn growth overall by spreading castings on their lawn and watering in.

A year ago I took some extra compost  added about 25% worm castings to it and applied to to bare spots in my lawn.

I have tried to repair these areas with many store bought products and even transplanted new grass into these areas and it just kept dying off for the last few years.

After the compost mix with worm castings were worked into the bare areas these areas have now fully grown over with grass.

I am here to say this method worked for me so there must be some truth to it.



Listed above are the top  ways how to use worm castings.

Now that you have discovered how to use worm castings, I am sure there are more uses that you will find just be creative and experiment.

One rule to remember less is more when using worm manure. About 25% by volume is about all you need in a single application, from my own experience there is no difference in using more in most cases. Using more than this amount is just wasted. Just guess because there is no ratio to follow.

Worm castings can be used to start and organically grow any kind of plant
