+Problems Encountered+ In visiting and corresponding with individuals who are growing Chinese chestnuts, I have made a few observations, as to problems that have arisen. +1. Site and Soil.+ The most successful trees from the standpoint of growth and production were those growing on fertile, well drained soil in which moisture was plentiful. The Chinese chestnut tree appears to be shallow rooted and to require good growing conditions. Dry ridges were unfavorable for growth, and in bottom land the trees frequently were subjected to late spring freezing of tender shoots. 2. Blight injury to the trees and weevil damage to the nuts seemed to be the most serious enemies of chestnuts. Seedlings varied considerably in their resistance to blight. Some of them showed no indications of blight; others were damaged but outgrew the injury; and a few trees were weakened and died. Weevils appeared to be quite prevalent. One grower reported almost 100% wormy nuts. It is my understanding that a spray program has been developed for control of the weevil. Mr. H. F. Stoke of Roanoke believes that the Illinois No. 31-4 chestnut (a hybrid) is resistant to weevil, probably because of its thick burs and closely set spines. +3. Cultural Care.+ Chinese chestnuts benefited from pruning; it being especially important to cut away the sprouts at the bases of the trunks. Mowing weeds and brush around the trees seemed helpful. Applications of nitrate of soda stimulated more rapid growth of young trees, and in limited amounts benefited the older trees. It appears, however, that there may be a danger of overstimulation which increases the hazard of limb breakage by snow and ice, especially in the case of younger trees. The largest crops of nuts, however, were frequently produced on trees of only moderate vigor. +4. Freezing damage to the bark of the trunks and large limbs.+ This occurred in the VPI Horticultural Department planting in 1945, when a temperature of about 17 deg.F. occurred after the trees had started growth in the spring. This injury appeared as a darkening of the outer bark and cambium. Trees that were severely damaged became weakened and tended to sprout vigorously from the bases of their trunks. Other trees overcame a slight injury with little apparent ill-effect. +5. Seedlings or Varieties.+ The question is whether to grow seedlings or grafted varieties. Seedlings are more easily propagated, the nursery plants less expensive, and the trees longer lived on the average; but seedling trees and nuts are quite variable. Named varieties are difficult to propagate, the nursery plants expensive, and stock-scion incompatability may occur; but the trees and nuts are uniform. Seedlings serve a useful purpose in developing new varieties; but with more planting of superior varieties and a fuller understanding of propagation methods, and of cultural care, chestnut growing on a commercial scale may be more likely to become a reality. +Future Prospects+
