High Altitude Gardening

Gardening in Valley County has its challenges. McCall has around 63 frost-free days, Cascade a few more.

Maintaining healthy soil is your No. 1 strategy for dealing with all gardening issues you may face. Composting can be a great way to maintain healthy soils to protect your garden from disease, weeds and low yields.

Growing plants and vegetables at high altitudes requires an understanding of what is possible and what is practical. If you are new to high altitude gardening, we invite you first to read Introduction to short-season gardening in Idaho (BUL 857).

View the following documents to learn more about short-season growing in Idaho.
