In response to an inquiry as to how weed competition near young trees is controlled, the replies are encouraging. Forty-seven practiced mulching; forty-five, mowing; thirty-four, occasional cultivation; twenty, regular cultivation, and a few others, slag or cinders around the trees. As is evident, some used several of the above methods. A few used none and suffered losses. Their honesty is admired, and their experience, disappointing as it is, is useful information. As to fertilizing, forty-three reported the use of manure in some form as the principal material; twenty-eight used nitrogenous fertilizer; twenty-one, a complete fertilizer. Other materials were, in order, lime, compost, bone meal, ammonium sulphate, wood ash, tankage. One used a mixture of muck and manure and got results in excellent growth where the use of muck alone produced unsatisfactory growth. Several reported injury from too much fertilizer or from too late an application. Tree growth was thus pushed on into late fall; the trees were too sappy to stand the winter freezes and suffered from winter killing. The same result was reported from "over-cultivation." In this connection, we refer back to the letter from Mr. H. P. Burgart, of Michigan, whose suggestions on cultivation and fertilizing are well worth careful study and practice by all who have had this trouble. It is possible that some planters, especially those whose trees are set on hillsides, where erosion is a robber of fertility, would modify Mr. Burgart's practice of turning under the green crop in the spring. They might prefer, as indeed might others who would like to see their green manure nearer the top of the soil, to disk in the green crop rather than bury it deeply with mouldboard plows. They would of course follow it up with repeated diskings until the time came for sowing another cover crop. This is, however, entirely in line with Mr. Burgart's recommendations. Pursuing this subject to its conclusion, we next asked: "_When young trees failed to grow with you, what percentage of these failures was due to_ ..." (various causes enumerated below)? The question was misunderstood. Many evidently gave percentages of all trees planted. Others, correctly, gave percentages merely of the trees which failed to grow. As nearly as could be arrived at, about 30 percent of losses were among trees that failed even to start; 40 percent failed from weak growth the first year or two; 10 percent from failure to maintain later growth; 16 percent were winter killed, and 3 or 4 percent died from rodent or similar (mole, gopher, deer, bear) injury. It is evident that by far the greatest losses were suffered within the first two years--not less than seventy percent. Probably more. It would seem that two years of intensive care should not be too burdensome a stint for a reward which lasts a lifetime.
