The Root Control Bag

For In-Ground Growing

The patented, original bag system that started it all… millions of bags sold since the first bag-grown tree was planted in 1980. The Root Control Bag is a soft-sided fabric container that helps you do a better job of growing and transplanting trees.

The Patented, Original Bag System of Growing

  • Fabric bag prevents damaging root circling
  • Root pruning produces healthier root structure
  • Keep 80% of the roots intact during harvesting
  • Extended harvesting season
  • Fastest plant rejuvenation after transplanting

How It Works

Healthy root system
Healthier Root Structure – No Circling

As the roots of the plant grow, they hit the fuzzy inside fabric of the bag. Roots do not circle on the fabric as they do against plastic. Instead the root is caught by the fuzzy inner surface of the material. The root penetrates the fabric. The tough fabric, however, prevents the root from expanding. The root is choked or girdled by the fabric. The choking causes the root to lose its apical dominance and lateral branching or pruning occurs inside the bag.

Intact root structure from Root Control Bag
Keep 80% of Root Structure Intact

With the Root Control Bag, approximately 80% of the root structure is harvested with the plant. By contrast, a study at Michigan State University showed that up to 98% of a tree’s root structure can be cut away with normal digging procedures. That means more plants survive the harvest and more gains for your business.

Transporting trees grown in Root Control Bags
Fast Rejuvenation After Transplant

Keeping a bigger and better root structure also means a faster growing, healthier plant once it is re-planted. A transplanted tree, grown in a Root Control Bag would only take 1-3 months to recover and start growing again. Compare that to a tree grown in a ball-and-burlap (b&b) that could take 2-3 years to rejuvenate.

Basically the bags allow an explosion of new plant growth in a shorter amount of time.

Harvest longer with Treebag
Extended Harvesting Season

With B&B, harvesting can only be done when the plant is dormant and when the ground is not frozen, severely limiting harvest times. With the Root Control Bag, the harvest window becomes much much wider. ProTip: don’t dig when the temperature is 100 degrees and don’t dig when the plant is coming into bud (for those who want to push the bag past logical limits).

Harvesting made easy with small ball size
Smaller Ball Size For Easier Harvesting

A typical 3-inch caliper tree in a standard ball-and-burlap weighs about 500 pounds and requires heavy equipment to move. With the Root Control Bag, the same tree would be several hundred pounds lighter meaning you need less equipment and your trees are accessible to more customers. The smaller ball size also makes it easy to shift a bag grown plant into a larger wooden box or plastic container. The bag grown plant will root quickly into the larger pot, ready for a quick sale.

Easy bag removal
Round Bottom Easy Bag Removal

The bottom of the Bag is applied by a hot melt glue process. The glue process leaves a flat bottom and no sewn seam through which a root can escape. The bottom of the bag is not creased or folded so roots do not grow into creases or folds making bag removal easy.

No Blow Over
Some roots will get through the fabric and this is normal. Most roots that penetrate will be fibrous feeder roots no larger than a pencil tip. At harvest these roots are easily severed. The roots that penetrate the bag stabilize the plant and prevent the trees from getting blown over.

Owner of Kuenzi Turf & Nursery: It's in the Bag

"...during this time we started using High Caliper’s 10” root control bag to produce these difficult tree types. We had resounding success with a 99 out of 100 survival rate...they’re even going to market about 2 years faster than bare root grown plants." Read More

"We’ve been running a 150-acre production operation farm with just 4 people 100% on In-ground ‘fabric containers.’ These Root Control bags are not only the healthiest way to grow trees, but they are by far the most efficient way to produce trees." Read More
