What is a potential risk when planting at the bottom of a hill?

Planting at the bottom of a hill can lead to higher susceptibility to frost damage due to the way cold air behaves in landscape positions. Cold air tends to flow downwards and collects in lower areas, such as the bottom of a hill or valley. This can create a microclimate that is significantly colder than areas situated higher up. The increased risk of frost can harm plants, particularly sensitive species that are not adapted to those cooler temperatures.

While other risks such as drainage issues can also be a concern at the bottom of a hill, the primary reason frost damage is more pronounced in this location is related to the accumulation of cold air. Understanding this aspect can help in making informed decisions about plant placement and selecting species that can withstand potential frost exposure at lower elevations.
