Zoreah
From Halachipedia
- Planting of any amount is forbidden. The applications of this prohibition are planting, grafting, removal of obstacles to the plant, fertilizing, watering, spraying insecticide, putting seeds in water, and moving a plant in a bored pot. [1]
- Washing one’s hands over plants on Shabbat is forbidden because watering a plant helps it grow and is forbidden on Shabbat. [2]
- One may not put tree branches in a vase with water on Shabbat; however, one may return them to water unless there are flowers on the branches. On Shabbat one may not add water to a vase with flowers or branches; however, on Yom Tov one may add water. [3]
