| Bodies of Water | Moderate temperature extremes and increase humidity |
| Vegetation Cover | Provide shade, wind protection, and moisture retention |
Mountain and Valley Growing Considerations
Gardeners in Pennsylvania’s mountains and valleys face special challenges. The state’s varied landscape affects the climate and growing conditions. Gardeners must adjust their plans to succeed.
In the Appalachian Mountains, it’s colder and the growing season is shorter. The high altitude means more wind, less sunlight, and a higher risk of frost. It’s important to choose plants that can handle the cold and use methods like row covers to grow longer.
Valleys in Pennsylvania can have frost pockets, where cold air settles. This can harm plants that don’t like the cold. Gardeners need to carefully choose where to plant and use strategies to avoid frost pockets.
