MB 336.2 – MB 336.3 – Using Trees, Roots, and Grass on Shabbos: Height Limits, Walking on Grass, and Watering Concerns

In this episode, we continue the laws of using trees and their roots on Shabbos. We explain when roots and low branches are considered ground and therefore permitted to use, based on whether they rise above three handbreadths. We also cover complex cases such as uneven ground, roots that bend downward, and when appearance from different sides affects the ruling.Next, we review the permissibility of walking on grass—why it is generally allowed even when the grass is long—along with precautions when grass becomes detached. We also discuss why washing hands over grass is prohibited due to watering, while pouring certain liquids or urinating on grass is permitted because they do not promote growth. Finally, we note added restrictions when eating in large gardens due to carrying concerns.
