Heya!!!
Hope this helps u!!!
Elevation in relation to the surrounding land – Cold air, frosts, and fogs settle in low areas, increasing the potential for frost and disease problems. For each 100-foot rise in elevation, expect a 5-10°F increase in spring night temperatures during a radiation frost/freeze event. The ideal site is an area of rolling land. Plant on slopes that are not too steep to be safely traversed with equipment. How far down a slope to set depends on the width of the valley at the base of the slope and on how well air can drain out of the valley to lower elevations. The tops of hills are not necessarily good sites as orchards located there are more vulnerable to advective freezes than the sides of hills. Also, soils on the tops of hills are frequently shallow due to erosion.
