It’s important to consider your climate when selecting plants for your garden so that you don’t waste time or money on plants that won’t survive in your area.
You can use the USDA Plant Hardiness Zone Map to determine which zone you live in if you’re not sure which hardiness zone applies to your location. The map divides Idaho into eight different zones based on average minimum winter temperatures, so you can easily find out which hardiness zone applies to your area and use it to select appropriate plants for your garden or landscape.
Which Planting Zone Does Idaho Fall Into?
Idaho is located in the western part of the United States and is known for its rugged beauty and diverse landscapes. The state falls into USDA Plant Hardiness Zones 3 through 7, with some parts of the state falling into Zone 8. The higher elevations and colder temperatures in northern Idaho make it a cooler climate than other areas of the state, with temperatures dropping low enough to support hardy vegetables such as kale, spinach, and Brussels sprouts. The lower elevations of southern Idaho are warmer and experience longer growing seasons, allowing home gardeners to enjoy tomatoes, peppers, squash, and other warm-weather vegetables.
The majority of Idaho falls into Plant Hardiness Zone 6 or 7. This allows home gardeners to choose from a wide range of plants that thrive in these zones. Cool-season vegetables such as broccoli, cabbage, lettuce, onions, parsnips, potatoes and turnips can all be successfully grown in this region. Warmer temperatures allow for warm-season vegetables such as corn, beans, cucumbers, eggplant and squash to thrive here as well.
When choosing what to plant in your home garden it is important to consider your location’s climate and soil conditions. Knowing which USDA planting zone you live in will help you determine which plants are best suited for your garden space. By understanding what plants grow best in your area you can ensure a successful harvest each season!
Identifying the Planting Zones in Idaho
Idaho’s gardening and landscaping enthusiasts often need to know the USDA Plant Hardiness Zone they live in. The Plant Hardiness Zone Map was developed by the United States Department of Agriculture (USDA) to provide gardeners with a guide for selecting plants that are likely to thrive in a particular location. Idaho is divided into 6 major planting zones, ranging from 3a to 7b.
The coldest zone in Idaho is 3a which covers the northern part of the state with an average annual extreme minimum temperature of -35°F. This includes areas near Bonners Ferry, Sandpoint, Coeur d’Alene, and Priest River. Zone 4a has an average annual extreme minimum temperature of -30°F and includes cities such as Lewiston, Moscow, and Boise.
Zone 5a has an average annual extreme minimum temperature of -25°F and includes towns such as Grangeville, Salmon, Cascade, and McCall. Zone 6a is slightly warmer with an average annual extreme minimum temperature of -20°F and covers cities like Twin Falls, Mountain Home, Hailey, and Burley.
The warmest zone in Idaho is 7b which covers a small area along the Utah border with an average annual extreme minimum temperature of 10°F or higher. This includes cities like St. Anthony and Rigby. It’s important to note that not every city in Idaho falls into one of these 6 major zones; some cities may be located in transition zones between two major zones or may even be located outside of any zone at all.
Knowing your USDA Plant Hardiness Zone can help you make well-informed decisions about what plants will thrive in your particular location. It can also help you determine when to plant and harvest certain vegetables so that you can maximize your harvest season each year. With this knowledge at your fingertips, you will be able to enjoy successful gardening experiences year after year!
Growing Season in Idaho’s Planting Zones
Idaho is home to a wide range of climates, from the high-desert region in the south to the mountainous forests in the north. As such, the state has been divided into five planting zones, each with its own distinct growing season. Zone 1, located in the northernmost part of the state, has a long growing season with an average last frost date of June 15th and an average first frost date of October 1st. Zone 2 is located further south and has a slightly shorter growing season with an average last frost date of June 30th and an average first frost date of September 15th. Zone 3 is located even further south and has a much shorter growing season with an average last frost date of July 15th and an average first frost date of August 30th. Zone 4 is located along the border with Oregon and has a very short growing season with an average last frost date of August 10th and an average first frost date of September 10th. Finally, Zone 5 is located in the high-desert region in the southernmost part of Idaho and has an extremely short growing season with an average last frost date of September 1st and an average first frost date of October 5th.
No matter which part of Idaho you live in, it’s important to be aware of your planting zone so you can plan your garden accordingly. Knowing your zone’s typical last and first frost dates will help you decide what vegetables to plant when, as well as how long they will need to mature before harvest. It’s also important to note that these dates can vary from year to year due to weather patterns; for example, if there are unusually cold temperatures or heavy rains during spring or early summer, your zone’s typical last or first frost dates could be delayed by several weeks. Even if you live in one zone but have access to another (such as having access to both Zone 2 and 3), it’s always a good idea to know what your options are for extending or shortening your growing season.
Idaho Planting Zone Temperatures

The average low temperatures vary across the state, depending on which zone you are in. In the northern part of Idaho, Zone 1 has average lows ranging from -20 to 0 degrees Fahrenheit. Moving south, Zone 2 has lows ranging from -10 to 10 degrees Fahrenheit. Zone 3 has average lows ranging from 0 to 20 degrees Fahrenheit, and Zone 4 has average lows ranging from 10 to 30 degrees Fahrenheit. The southernmost part of Idaho, Zone 5, has average lows ranging from 20 to 40 degrees Fahrenheit.
The warmest area of Idaho is located in the southwest corner, with an average low temperature in Zone 5 reaching 40 degrees Fahrenheit during the winter months. On the other end of the spectrum, Zone 1 in northern Idaho experiences temperatures as low as -20 degrees Fahrenheit in winter months. Knowing your local planting zone and its corresponding temperature range is important for successful gardening in Idaho!
Climate
The climate of Idaho is generally cooler than other states due to its northern location. It has four distinct seasons, with hot summers and cold winters. The average temperature ranges from the low 40s in the winter to the mid-80s in the summer. Idaho’s climate also plays a role in determining its planting zones. The amount of sunlight and precipitation as well as the temperatures all factor into which plants will thrive in Idaho’s growing conditions.
Elevation
The elevation of Idaho also affects its planting zone. As elevations increase, temperatures decrease, so areas at higher elevations may have cooler climates than those at lower elevations. This means that plants that thrive in cooler climates can be grown at higher elevations, while warmer climate plants can be grown at lower elevations.
Soil Types
The soil types found throughout Idaho vary depending on the region and elevation of the area. Soils range from sandy loam to clay loam and some areas even have volcanic soils which can affect what plants are able to grow there and what planting zones they fall into.
Rainfall
Rainfall plays an important role in determining which plants can be grown successfully in Idaho. Areas with higher rainfall tend to have a wider variety of plants that can be grown, while areas with lower rainfall may only support certain types of plants due to limited water availability.
All of these factors play a role in determining what planting zone an area falls into within Idaho. With its diverse climate, soil types and elevation, there is something for everyone when it comes to gardening and growing plants in Idaho.
Conclusion
Idaho consists of two planting zones, USDA Hardiness Zone 4 and 5. This means that the majority of the state experiences harsh winters and climates that are more suited to cold-tolerant plants. Idaho gardeners should choose plants that are adapted to their zone and also take into account local microclimates, such as those found in urban areas or mountainous regions. It is important for gardeners to research the right plant varieties for their area and understand how they will be affected by Idaho’s changing climate. By doing so, they can ensure that their gardens thrive for years to come.
Overall, planting zone is an important factor when planning a garden in Idaho. Gardeners must be aware of the specific needs of their climate zone and take into account any variations due to local microclimates. With proper knowledge and preparation, gardeners can create a thriving landscape that will bring beauty and joy for years to come.
