heaving
 n.— «The changing temperature of our winters causes garden soil to expand and contract. This process can literally lift a plant out of its planting hole in the garden. This process is known as heaving. Many newly planted perennials succumb because this heaving of the soil exposes their roots to the elements. If a plant is impacted by heave, press it down and into the hole and make sure the roots are in full contact with the soil. Add an additional shovelful of mulch around the base of the plant.» —“The Garden Life: Falling leaves provide as much color as spring flowers” by Robb Rosser Columbian (Vancouver, Washington) Dec. 17, 2008.
