Product Details

Worm Castings allow plants to quickly and easily absorb essential nutrients and trace minerals. This is possible because Earthworms grind and uniformly mix the nutrients into simple forms, which are easily absorbed by the surrounding plant life. Despite the fact that many chemical fertilizers list many nutrients and have higher laboratory analysis percentages, the nutrients are not broken down in such a way that the plants can readily use them.

Agrowinn Worm Castings:

  • is environmentally friendly and non-polluting

  • is not quickly soluble and has good residual

  • loosens compacted soil and enhances plant feeder root fertility
  • does not burn plants or seedlings

In addition to the abundance of available nutrients, worm castings also provide a perfect mix of nutrients that are available to the plants and vegetables for long term nutritional needs. This allows plants to feed as needed for weeks and months at a time, as the worm castings release their precious nutrients into the surrounding soil.

Chemical fertilizers usually provide only synthetic nutrients, much of which are quickly lost into the soil during watering. Since the plant's root system can absorb only so much material over a given period of time, much of the value of this nutrient flow is wasted. Chemical fertilizers are also detrimental to soil microbiology, frequently bypassing and sometimes destroying much of the beneficial microbial and bacterial components of the soil. At the same time, many of these synthetic nutrients are absorbed indirectly into your plants and food.

The particular structure of Earthworm castings is such that it promotes soil aeration because it doesn't pack together when mixed in soil. As a result, you get a much more "open" soil, which in turn promotes rapid plant growth. In addition, Earthworm castings improve soil drainage, cutting down on water-logged soil which promotes root rot, And, since Earthworm castings contain absorbent organic matter (bio-humus), the soil's water retention capacity improves.

Annuals & Perennials:

Place a handful of castings into each hole as you plant. use 1/2 cup for smaller plants, more for larger plants. Cover and blend with soil or planting mix. Also, apply castings four times per year, at the rate of 10 lbs. per 100 sq. ft., or once a year at the rate of 20-30lbs. per 1000 sq. ft. For planting beds, mix six inches of compost into the soil. Add castings at the rate of 20lbs. per 1000sq. ft.

Roses, Trees, Shrubs, Berries, and Other New or Transplanted Ornamentals:

Mix one part Worm-Cast to 3-4 parts potting soil, planting mix, or organic compost. Keep in mind that Worm-castings are very potent and there is no need to over do it.

Castings mixed at a 1 to 3 ratio: 33% castings

Castings mixed at a 1 to 4 ratio: 25% castings

Established Plants, Potted Plants (indoors or out) and Other Specimens:

Side dress during the growing season at the rate of 1/2 cup per 6" pot, or one cup per linear foot of row once every two months.

Lawns - New

Apply Worm-Cast at the rate of 20-30lbs. per 1000 sq.ft. of lawn area. Work lightly into the topsoil. Mix in grass seed, cover with shredded straw, and moisten.

Lawns - Established

Use a lawn spreader (yes, Worm-Cast is dry enough to spread even with a hand-held whirly bird type spreader) applied at the rate of 4-6lbs. per 1000 sq.ft. Repeat every 45 days during the growing season. Another very acceptable methodology is to "top dress" once per year at the rate of 20-30lbs. per 1000 sq.ft. This is only a very thin layer of castings. We have had good success with "top dressing" by pre-mixing Worm-Cast with a good quality organic compost or soil amendment at the rate of one part Worm-Cast to four parts organic compost.

Remember that Worm-Cast is safe to use and will not burn plants in any concentration. Best results are obtained by using Worm-Cast sparingly.
