Effects of root pruning and time of transplanting in nursery liner production
Root pruning and care during the first two nursery transplantings of four tree species significantly increased the percentage of plants with good root systems. The earlier the plants were moved from the seedflat into peat pots and then into gallon cans, the higher the percentage of plants with good root systems, and the larger they grew in caliper and height. Plants root-pruned during the early moves were larger than those not pruned. However, later root pruning resulted in smaller plants than those moved earlier, or than those moved at the same time but not root pruned.
