ConShape™ is a new PGR product that controls the leader growth of Christmas trees as a substitution for mechanical pruning. With ConShape™, central leaders cease growth a few days after application and retain the full number of buds on the leader which will result in a denser and more attractive branching in the following year. ConShape™ contains a naturally occurring plant growth regulator S-abscisic acid (S-ABA) as the active ingredient.

The primary application use for ConShape™ is for the purpose of controlling the growth of the terminal leader in Christmas tree production, eliminating the need for manual pruning.

(Precision application to the leader is achieved through the use of an Easy Roller application tool.  Easy Rollers for ConShape™ application are now available from Mycorrhizal Applications and ConShape distributors.)

Currently registered in the following states: Oregon, Washington, Michigan, Wisconsin, North Carolina, New York, and Pennsylvania.

(We are actively seeking Christmas Tree growers in the above-listed states to participate in an ongoing ConShape trial through 2021 and 2022.  Growers who volunteer to participate will receive a $100 incentive towards their Christmas Tree Association membership.  Please contact us at for more information or to sign up for this program.)
