The Whitcomb System®   

                                                                                                                       

RootMaker®
   root pruning containers
 

 

Designed to create a more fibrous root system by air root pruning, the often imitated RootMaker® container series now has 18-, 32-, and 60-cell plastic propagation "plug" trays, as well as the original 4-pack, 1-gallon round pot, 1-gallon square, 3-gallon, the unique 5-gallon Grounder, and a new 5-gallon based on the highly successful 3-gallon design.
 

 

Knit fabric in-ground containers


 

The in-ground "grow bag" or "tree bag" has evolved past the early dark fabric models of the early 80's as we have continued to learn about roots and their reactions with certain fabrics.   The RootMaker® knit fabric bag creates a compact, fibrous root system and a means for a simple, quick harvest with it's precise openings. 

 
RootBuilder® containers

 

While holding a tree after harvest, the RootBuilder® expandable container continues to improve the root system by directing root growth toward air-pruning openings and stimulating root branching.  This highly successful container was recently redesigned to be more efficient with air-root-pruning. 

RootSkirts®

Temperature protective sleeve for production containers.

RootTrapper ®

 

Laminated fabric above-ground container which not only conserves water but also stimulates root branching by root-tip trapping and remains as much as 20-25 degrees cooler than traditional black plastic containers.  This tough but soft-sided container can be shipped as is.  Cut and remove when the tree needs to be shifted to a larger container or is being prepared at the landscape site.  The Root Trapper® will not scar the stems of other trees when stacked for shipping and this "pot" won't fall off during handling. The RootTrapper® is also custom made to fit pot-in-pot production and comes in 3 models, depending on your drainage/aeration requirements.
Visit www.rootmaker.com for more information.

 

When exposed to sunlight, all black containers get hot.  If a black fabric container has a porous sidewall, some evaporative cooling occurs but only at the expense of losing large quantities of water.  Instead, RootTrappers®, because they are white, reflect heat while conserving water by slowing water exit and increasing absorption by creating a fibrous root system.

 
Chaps®

 

Protects stems of young trees from herbicide injury and temperature extremes.
