In the heat of summer the hair roots are much more likely to dry out. The new growth has hardened and is less likely to be injured and won't transpire as quickly. The plant still has time to put down some new roots to stabilize it. I recommend a high potassium fertilizer to stimulate new root growth. Harvesting Methods Bare Root Plants Advantages of planting bare-root plants are mostly economical.
Plants are less expensive to produce because of the ease of harvesting, storing and shipping.
Many species respond well to bare-root harvesting. A greater portion and longer roots are retained after harvesting and roots are easily inspected at planting time. Damaged roots can be trimmed and girdling roots can be removed before planting. Bare-root plants should be planted while they are completely dormant. The amount of roots harvested depends upon soil type, irrigation practices and root pruning during the production period.
