Planting Season in Idaho: Your Essential Spring Gardening Guide


Embracing Idaho’s Spring Planting Season

As the frosty fingers of winter loosen their grip and the promise of spring fills the air, gardeners across Idaho eagerly anticipate the opportunity to dig into the soil and bring their gardens to life. With its diverse landscapes and fluctuating climates, Idaho presents a unique set of challenges and opportunities for planting enthusiasts. In this guide, we’ll explore a tailored approach to spring planting in Idaho, focusing on what to start planting and when to ensure a successful growing season.

Timing Matters

In the world of gardening, timing is everything, especially in a state like Idaho with its varying elevations and microclimates. Knowing when to start planting and transplanting different crops can mean the difference between a flourishing garden and disappointment. Let’s take a closer look at some popular plants and their optimal planting timelines:


Tomatoes are beloved but frost-sensitive. To begin, start seeds indoors in late March or early April. After the frost risk subsides, typically by mid-May in Idaho, transplant seedlings outdoors. Be sure to choose a sunny, well-drained spot for best results.


Peppers, like tomatoes, love warmth. Start indoors 8-10 weeks before the last frost, usually in early to mid-March. Transplant outdoors after the soil warms and frost danger is gone, around mid-May, similar to tomatoes.


Plant directly in warm soil. Then, sow seeds or transplant seedlings outdoors by mid-May. Support vining varieties and maintain consistent moisture for healthy growth.


Plant once soil hits 60°F (15°C), usually by mid to late May in Idaho. Choose sunny, spacious areas with well-amended soil. Sow seeds directly or transplant seedlings.

Leafy Greens:

Plant early in spring when soil is workable and temperatures are above freezing. Sow seeds directly in early to mid-April for an abundant harvest.

Amidst Idaho’s stunning landscapes and rich agricultural heritage lies the ideal backdrop for gardening triumphs. As you follow this guide, meticulously timing each crop, anticipate a season brimming with rewards. So, roll up your sleeves, dig in, and witness your home garden flourish.
