RootZone Planting Mix
There are hundreds of soil enhancement products on the market today. Some are very good quality while others are just cheap-grade, low quality products that provide little if any beneficial nutrients to the soil.
Formulated by Brent and brooks Wilson and the folks at Farmers Organic, RootZone Planting Mix is a superior blend of organic matter great for use when planting any types of plants outdoors in all soil types. It is guaranteed to break up hard clay soils and compacted soil; improving drainage and providing ample space for roots to grow, and highly facilitates the rooting in process after having planted new plants.
RootZone is made up of 3 parts 10 year old composted hardwood grindings to 1 part Farmers Organic High Cotton. What is "High Cotton"? High Cotton Compost consists of 100% cotton residuals. Every part of the cotton plant, the lent, stalks, bowls, leaves, and seed meal has been composted a minimum of 3 years to ensure it is chemical free and consistent. The average N-P-K of High Cotton is approximately 1-1-1. It is full of beneficial micro-organisms that plants love, and will not burn the roots of plants.
How To Use RootZone
RootZone is available in 20 quart bags and can be used as a beneficial soil amendment when planting ornamental shrubs and trees, annual and perennial flowers, vegetables, and almost any other type of plant in the garden. It is not suitable for use alone in container gardens except to add a few handfuls to enhance the potting mix.
NOTE: Before using, you'll need to determine how much RootZone to use to improve the porosity of the native soil. To test the porosity simply dig up a handful of the native soil. The soil should be damp but not wet. Squeeze the soil in the palm of your hand. If the soil crumbles this means it has good porosity. If it molds like modeling clay porosity is bad.
As a general rule of thumb we recommend adding the following amounts of RootZone to the native soil removed from the planting hole...
When planting individual plants in undisturbed soil
Soil of average to good porosity: 1 Part RootZone to 2 to 3 Parts Native Soil
Dense, compacted soils: 1 Part RootZone to 1 Part Native Soil
Note: Dig planting hole 2 to 3 times as wide as the root ball of the plant and thoroughly blend the RootZone with the native soil removed from the planting hole.
When tilling or turning into a planting area
Soil of average to good porosity: Till or turn in 1/2 to 1 inch layer of RootZone to a depth of 6 to 12 inches.
Dense, compacted soils: till or turn in 1.5 to 2 inch layer of RootZone to a depth of 6 to 12 inches
