The use of rock dust in the garden is not new. It is over 420 million years old to be exact!
Rock dust contains two thirds of all non-synthetic minerals known to man, and is a natural method of adding essential trace elements to your soil.
Benefits include high yields, tastier fruit and vegetables and increased resistance to pests and drought.
A Scottish couple discovered that if they added crushed rock dust to their garden, the resultant produce had ten times the nutrients of store bought ones.
Plants constantly suck minerals out of the soil, slowly depleting this ancient reserve.
Restoring those micronutrients. has many rewards: Plants with an abundance of minerals in the garden soil grow bigger, faster and healthier.
Rock Dust has a very high level of minerals and trace elements (57 different trace elements) in well balanced quantities.
Eight of the seventeen elements essential for plant growth are micronutrients. Ground to dust, trace minerals and micronutrients are small enough to pass through cell walls of plants.
Rock dust can be used successfully on all plants and vegetables, such as: potatoes, grains, beans, beets, spinach, lettuces, tomatoes, strawberries, oranges, and many other fruits and vegetables.
Add rock dust to your garden soil at least once per year, seasonally would be better if you are able to. Also apply rock dust as a spray once per month.
Different size rock dust has different levels of effectiveness to the plants that are nourished by it. Smaller particles dissolve quicker than larger ones.
The finer the rock dust is, the more easily soil bacteria decomposes the dust particles and releases the trace elements contained with them, putting the trace elements into a form which the plant roots can absorb.
While chemical fertilizers may produce more immediate visual results, when you add Rock dust you are adding a huge range of minerals and trace elements for long term soil health.
The application of rock dust during the spring once per year will encourage the root systems of trees , lawns, roses, vegetable gardens. Apply rock dust just before the rainy season to take advantage of mother natures rain.
How to Use Rock Dust in Your Garden:
Spread a light layer of rock dust around vegetable plants. Allow it to sit overnight, then spray it down with filtered water.
You can also try mixing rock dust into a liquid form, then adding seaweed. Spray the mixture onto plant leaves. This revitalizes the plants and helps them in repelling pests.
To further protect against pests, you can also spread a light layer of rock dust around your garden. Wait for 24 hours, then water it well.
Roses love rock dust! Apply rock dust several times per year, approx. 1 cup rock dust per plant, watered in well. For best results add 1 cup rock dust to 1 gallon filtered water then water base of rose.
You can also make a rock dust milk by adding 1 cup rock dust to a panty hose, tie into a ball and suspend in a gallon of water. Allow to sit over night. Pour into sprayer and spray leaves.
Not only can rock dust be used to enrich your soil, it can be very effective at controlling certain pests. For example, snails are repelled by its high silica content.
Rock dust is most effective when mixed 50-50 with organic compost and a handful of soil to add some microorganisms. The addition of compost just gives the rock dust a head start as food for the microorganisms.
Some gardeners add a little rock dust to their compost piles, either in the beginning or along the way. Some spread rock dust on their soil and then cover it with compost.
Others mix rock dust into their finished compost right before application. All ways seem to work; the important thing is to combine the dust with lots of organic matter.
Rock dust is environmentally friendly and will not leach into your ground water. It is also a slow release natural fertilizer.
