The height of poinsettias for pot plant marketing can be effectively reduced by using soil applications of the chemical, CCC, according to tests conducted with the cooperation of growers in San Mateo and Alameda counties. Difficulties in keeping potted plants from growing too tall were solved by using 2 ounces of a solution containing CCC at the rate of 1/2 to 1 ounce of the 50% material per 3 quarts of water. When applied just before, or immediately after transplanting from the 21/4-inch pots to the 5- or 6-inch pots, the CCC treatment resulted in well-proportioned plants of high commercial quality.
