Oak Grove Nursery prides itself as being a Certified Rootmaker® Grower.
We start our seedlings and rooted cuttings in the Rootmaker® propagation trays. Rootmaker® propagation cells direct root growth to various air pruning points throughout the cell using a series of vertical ribs and horizontal ledges. Air pruning the roots helps to create a fibrous root system with an increased uptake of inorganic nutrients and water. The Rootmaker seedlings and cuttings adapt faster than bareroot material and suffer less transplant loss. Best of all FALL planting!
Knit fabric containers continue the root branching procedure either by root tip trapping or root constriction. The mesh bag slips snugly into concrete cinder block cavities. Reduced temperature provided by the cinder block, in combination with thousands of root pruning points in the bag produce a vigorous liner with an unmatched root system. Cinder bag grown plants are comparable in size to a 2 gallon container grown product. Plant material size is variable depending on species. A white 5" bag will be used for certain plant species as needed.
Dr. Carl Whitcomb's Rootmaker® container is simply the best air pruning plastic container on the market. A series of vertical ribs and horizontal ledges enable this container to actively direct growing roots to side openings which allow for air root pruning. A well branched root system will be created allowing for increased uptake of inorganic nutrients and water. This increased nutrient and water uptake will lead to greater top growth and enhance transplant success.
A white 8" bag's unique inner lining stops roots from circling and continues to stimulate root branching by trapping root tips with its black, spun-bonded fabric. The outside of the bag is laminated with a white coating to help greatly reduce container temperature so roots are not harmed on the sunny side as with black pots. These bags also reduce water usage because water only seeps out the hundreds of holes created by the base stitching. An 8" bag is comparable in size to a 3-5 gallon container grown plant. We use this size bag for our larger tree and shrub species such as Oaks and Dura-Heat Birch clumps.
