(3) Cutting plants in midsummer, or later, caused new growth at the expense of reserve food stored in the roots, and gave the best results by either killing the plants or weakening them. CUTTING VS. SPRAYING DANDELIONS. At this station, French (1911) concluded from his experiments and observation that spraying did not remove the leaves so completely from treated plants as did cutting, since plants which survived six or more cuttings could withstand as many sprayings and probably more. In order to obtain further data on this point, three experiments were conducted as follows: Experiment 1. Ten pairs of dandelion plants of practically the same size, and growing within a foot of each other were selected. One plant of each pair was cut off below the crown, while the other plant was " sprayed off " with twenty per ct. iron sulfate solution. The3e plants were cut off and "sprayed off" on the same date five times during the season, the first treatment being given on May 3. Following each treatment, the "sprayed off" plants were the first to respond by making new growth. These plants usually made a growth of from three to five inches, and had four or five leaves before the cut-off plants were large enough to be again cut off. At the time of the third treatment, only one of the cut-off plants was alive, while four plants of the "sprayed-off" series were living, two of them having made a vigorous growth.
