Q&A for How to Make Worm Castings Tea

Yes. I have had success that surpasses "fake nutrients" or chemical fertilizers. For a science project, my 6th grader son compared regular soil for planting 30 violas to 30 viola plants planted in the same top soil with liquid fertilizer bought at a 'garden' store to worm casting tea with the same top soil and 30 more violas. The 30 violas with the worm casting tea had 80% more flowers and were an inch to a 1/2 inch larger.

There is almost no macro nutrient content to worm casting tea. For hydro gardening you'll need to add nutrients from another source. Worm casting tea adds microbes to the soil or solution, which helps break down the soil, making the nutrients readily available to the plants.

None - use it pure. You don't want to dilute because the more microbes that reach each leaf, the better the result.

Yes. Aerated VermiCompost Tea (AVCT) is beneficial to all plant life.

Yes. The same principle applies to virtually all plants. Looks at it this way, if we didn't have bees and worms, the world would be a very different place. 90% of the plants in nature that are in a healthy environment have worms in some sort of numbers in their root zone. You're just adding what nature usually supplies on its own.

No, the microbes feed off the sugars in the molasses in order to multiply. Without it, they would run out of food, and die off.

I believe that the aeration time is the same (24-36 hours). The only difference would be concerning the amount of castings. If you use more castings, then you would probably need to use a container larger than the average 5 gal pail, and therefore a larger and more powerful air pump.

None. It should be used as a soil amendment. I'm not aware of any help from it by spraying it on the foliage.

Yes; just split all the ingredients by half (or quarter, etc.).

You could probably add it to dry soil, or cardboard, and dehydrate it. Or, pour it back into your compost heap, or on land, or into pots you intend to use. The microbes may dry out but usually they will rehydrate when it rains or you add water. Don't let it have a lack of oxygen, or become anaerobic.

Microbial life needs a place to live (the water) and food to ea t(the molasses). As long as you kept enough water and molasses in the bucket with the agitation, it wouldn't "sour" but why not make custom sized batches? What I don't use on my potted plants, I add to my raised beds or my composter. You can dump excess almost anywhere plants need food and it won't be wasted.

Yes. It's worm dung which will decompose like any other dung. If you don't want to put it on your plants, then put it in your compost.
