Cabled trees fail, too many in fact. The Arborist at Olson Tree Care is not talking about those with low tensile strength Mickey Mouse systems. Olson Tree Care is talking about the trees with the best hardware, installed by the best Tree Services in Des Moines, per industry standards.

       Cabling changes the load through pulling force. The load is transferred not shared. Every branch cabled is increasing load on another branch. Wind loading makes this dynamic.

When cabling 2/3 the distance of the overall stem from the axis, force is placed on an isolated location which causes localized displacement of the branch.

       Olson Tree Care has developed a new technique. Transitional supports provide force multiple loading points that allow for even displacement of the branch.

       Transitional Support Systems.

- Supplemental supports that closely mirror tree mechanics.

Tier 1. Use of fixed brace close to axis.

Tier 2. Install cable (just taut), 1/3rd the length of overall stem, from axis.

Tier 3. Install cable (less than taut), 2/3rd the length of overall stem, from axis.

       The Arborist at Olson Tree Care has experimented with varying degrees of Transitional Support Systems sometimes forgoing the brace and utilizing only the 1/3rd and 2/3rds of the way cables in different configurations. In other cases utilizing 3 levels of cables.

One constant is always implemented.

- In every system the transitional placement and tension is always done in a way that duplicates tree mechanics. (location/tension)

Just as trees stay flexible in growth so should we.
