Volcanic Rock Dust long been our main source of natural fertilizer built into our soil mixes for long-term soil & plant health. There is an important relationship to plant health that starts with minerals (like this rock dust) that are consumed by microbes then re-incorporated back into the soil as plant available nutrients readily available to your plants. Growing fruits and vegetables in mineralized soils can produce nutrient dense foods supporting human health. Growing ornamentals like houseplants in a soil that contains rock dust helps create plants with stronger cellular structure and stronger immune systems helping with pest prevention. This volcanic rock dust contains an abundance of macro/micro nutrients and trace elements making it an excellent source of mineral fertilizer in new soil mixes as well as re-invigorating depleted soils.
Application:
1 pound = aprox. 1 cup
For all plant types. Houseplants, fruits, veggies, herbs, succulent/cactus, citrus, ornamentals.
5 pound bag will treat:
240 potted plants at 1tsp per pot
500sf garden bed space
Up to 20cuF new potting soil
Potted Plants:
Use 1-2 teaspoons per 1 gallon pot size. Dust around topsoil, scratch in with a fork or stick if topsoil is dry/caked over. Can also mix with water and apply when plant needs watering. Apply at beginning of growing season, can be reapplied as needed, in general 2x-3x a year.
In Potting Soil:
Use up to 1-2 cups of rock dust per cuF of new potting soil mix for herbs & vegetables. 1/4-1/2 cup per cuF for lighter feeding plants such as houseplants & ornamentals.
Garden/ Raised Bed Applications:
10 lbs per 1000 sq.ft. or 1 lb per 100 sq.ft.
Dust lightly without caking (apply like powdered sugar over the soil surface).
Apply Every 2-3 months or min. 1-2 times per year or apply with each new crop planting.
Water after top dressing. (If you dust over flowering plants - water down the dust).
Any plant will benefit from mineralization, including Natives.
Trees:
Broadcast around center canopy and beyond drip line as far out as possible.
Use about ¼ pound per inch of Trunk diameter.
1 lb can cover 100 sq.ft.
Dust lightly without caking (like powdered sugar over the soil surface).
Seeds:
Add directly to seedling soil mix at 1/2-1 cup per cuF or dust the top of the soil after planting seeds, before watering.
Compost:
Excellent added to compost piles at the same aprox. rates as potting soil, or a dusting at every layer. Dust surface of worm bins or mix with your worm feed to increase mineral content of final product. Worms love a meal with rock dust!
