Don't worry if you add a little extra, unlike chemical fertilizers, worm castings won't harm your plants. Worm casting tea is made by steeping worm castings in water. The tea can be poured over the potting soil or sprayed directly on foliage.

In any way, what are worm castings high in?

Analysis of earthworm castings reveals that they are rich in iron, sulfur, calcium, nitrogen, phosphorus and potassium (NPK rating: 5.5. 3). They are much richer in nutrients than bulk compost, therefore application rates are much lower. Chemical fertilizers are a one-shot wonder.

In spite of that, how long do worm castings last in soil? You will find that most potting soils have a nutrient life for 2 to 5 days, where worm castings will last up to 6 times as long.

Yet, are worm castings high in nitrogen?

Worm castings contain five times more nitrogen, seven times more phosphorus and 11 times more potassium than ordinary soil. Worm castings or vermicast are both just another way to say worm manure. It turns out this stuff is awesome for your soil and plants.

Can worm castings go bad?

This means only that oxygen, moisture, and temperature remain fairly consistent from the start. With these things in place “fresh” worm compost remains viable for up to three years, or more!

Are worm castings poop?

Castings (or casts) are the excrement of earthworms. In layman's terms, it's worm poop. As worms digest food, they leave their castings behind in the bedding or soil where they live. And that's a good thing because these castings are nature's most perfect plant fertilizer.

What is earthworm poop?

There it is crushed and ground apart before moving into the intestine, where it is broken down further by digestive enzymes. Some of the food is passed into the bloodstream for use by the earthworm, and the rest passes out the anus as castings (worm poop).
