It should be applied to soils prior to planting and can mixed with compost or manures for additional soil building benefits. The premium powder grade is an excellent nutrient resource for all types of flowering plants including bulbs, fruits, shrubs, trees and vegetables.

I used this and the fish bone meal before planting my garlic and shallots this fall. Excellent product!
I wouldn't attempt to garden without it! So glad I got it before it was out of stock.
This product arrived very well packaged with no damage. Thanks grow organic for this product, I am using it on my fruit trees and potted citrus!
I am making a soil blocker recipe and this was the perfect addition! Arrived timely and was VERY well packaged! Love Grow Organic!!
