Which practice should be performed after planting to ensure proper establishment?

Watering thoroughly after planting is essential for ensuring proper establishment of a plant. This practice helps to settle the soil around the roots, eliminate air pockets, and provide the moisture necessary for the roots to begin their growth and development. Watering deeply encourages the roots to grow deeper into the soil where they can access more nutrients and water, which is crucial for the plant's long-term health and stability.

Additionally, adequate watering is vital for activating the soil's beneficial microorganisms and promoting soil health, further aiding the establishment process. It supports the plant in overcoming transplant shock, which can occur when it is moved to a new location. This initial thorough watering step sets the foundation for the plant's future growth and development, making it a key practice in post-planting care.
