Which condition is NOT ideal for tree transplanting?

Transplanting trees requires careful consideration of various environmental conditions to ensure their survival and successful establishment. Frozen ground is not an ideal condition for tree transplanting because the ground being frozen makes it difficult to dig holes for the new trees and to establish a proper root system in the new location.

When the soil is frozen, roots cannot easily prepare to grow into new soil, and the stress from being uprooted without proper conditions can hinder their recovery. In contrast, well-watered soil provides necessary moisture for the new tree, favorable weather allows for favorable temperatures and conditions for root establishment, and spring is often the best time for transplanting as the trees are just beginning to actively grow, promoting quicker establishment. These other options represent conditions that facilitate a successful transplant process, making frozen ground a notably unfavorable condition.
