2024 USDA Hardiness Zone Changes

In November of 2023, the USDA updated its plant hardiness zone map for the first time since 2012 – not surprisingly, lots of places are warmer than they used to be.
A full 63% of Mirimichi Green customers saw a half-zone change or more. Mirimichi Green produced a guide to help our users in updated USDA Hardiness Zones.

How do I know if my USDA Hardiness Zone changed?

You can search the 2023 USDA Plant Hardiness Zone Map by zip code to see if your area has changed since 2012.

Example of searching the USDA Hardiness Zone map by zip code.

What can I do if my USDA Hardiness Zone changed?

If your zone changed but is still the same number, there’s probably not a lot you need to do, except start to prepare for things to continue getting hotter. As in the example above, Clinton, NC, changed from zone 8a to zone 8b, a halfzone. But the it’s still in zone 8.

If you moved up a number level, like from zone 7b to 8a, you may want to consider making some changes.

For new plantings:

Consider updating your list of go-to flowers, shrubs, and trees to varieties better suited to your current zone. For a list of examples, you can download our PDF below which describes some considerations if you moved up a number level. Please print and use the relevant page. We hope it’s helpful for your staff and customers.

For existing plants:

Improving soil conditions can go a long way in helping established plants continue to survive and even thrive in higher zones. Consider CarbonizPN Soil Enhancer to improve soil fertility and reduce water needs in an increasingly challenging climate.

What is the USDA Hardiness Zone Map?

The USDA Plant Hardiness Zone Map is a valuable resource for gardeners and landscapers in the United States.

The geographical map divides the country into zones based on the average annual minimum winter temperature. Each zone represents a range of temperatures and is useful for determining which plants are likely to thrive in a particular location.

1. Temperature Zones: The map is divided into zones defined by 10-degree Fahrenheit increments. These zones are further subdivided into “a” and “b” sections, each representing a 5-degree Fahrenheit difference.

2. Guidance for Planting: The map guides gardeners and landscapers in selecting plants that are most likely to survive the winter in their region. Plants are often labeled with their hardiness zone information.

3. Limitations: The zone guide certainly doesn’t account for everything. Limitations of the zone map include the impact of microclimates, soil conditions, summer heat tolerance, wind exposure, precipitation and water availability, local typography, season length, and extreme weather events.

Topdressing Cool Season Grasses versus Warm Season Grasses with CarbonizPN

Cool-season grasses, such as Kentucky bluegrass, tall fescue, and perennial ryegrass, are commonly found in the Northern United States. They thrive in cooler temperatures and have a growth spurt in spring and fall. These grasses are known for their dense, lush growth.

On the other hand, warm-season grasses, such as Bermuda grass, St. Augustine grass, and Zoysia grass, are commonly found in the Southern United States. They thrive in hot temperatures and have a growth spurt in summer. These grasses are known for their durability and ability to withstand heat and drought.

One major difference between cool-season and warm-season grasses is how they propagate. Most cool-season grasses are bunching grasses, meaning they grow in clumps and do not spread through rhizomes or stolons (Kentucky Bluegrass is a notable exception). This means that overseeding is often necessary to fill in bare spots and keep a dense lawn. Warm-season grasses, on the other hand, are spreading grasses and grow through rhizomes or stolons. This means that they can fill in bare spots on their own and do not require as much overseeding.
When it comes to maintenance, the needs of cool-season and warm-season grasses differ as well.

  • For cool-season grasses, overseeding, topdressing, and aeration are important in the fall to encourage healthy root growth and prepare for the winter.
  • For warm-season grasses, these tasks are typically done in the spring or early summer to prepare for the hot summer months.

Topdressing with products like CarbonizPN can provide benefits for both types of grasses, including improved soil health and nutrient uptake. Topdressing is often thought to be labor-intensive, but belt-driven equipment, like the Ecolawn Applicator, can make this process a breeze.

Overall, understanding the differences between cool-season and warm-season grasses is important for proper lawn maintenance and care. By knowing the unique needs of each type of grass, you can ensure a healthy and vibrant lawn year-round.

The Magic of Biochar: A Sustainable Solution for Modern Landscape Management


As the CEO of Mirimichi Green, I am proud to be at the forefront of sustainable and innovative solutions for modern agriculture. One of our core ingredients is biochar, an incredible material that has been used for centuries to improve soil health and fertility. In this blog post, we will dive into the fascinating history of biochar, its characteristics, current trends, and an overview of the product landscape for companies producing biochar products.

A Brief History of Biochar

Biochar has a rich history that dates back over 2,000 years. Its origins can be traced to ancient Amazonian civilizations, where indigenous people created a highly fertile soil called “terra preta” (meaning “black earth” in Portuguese). By incorporating biochar into the soil, they were able to transform nutrient-poor, highly weathered soils into highly productive agricultural lands. This ancient wisdom has been rediscovered in recent years, sparking a renewed interest in biochar and its potential to address modern agricultural challenges.

What Makes Good Biochar and Less Good Biochar?

Biochar is created through a process called pyrolysis, which involves heating organic matter (such as wood, crop residues, or manure) in a low-oxygen environment. The quality of biochar can vary greatly depending on the feedstock and production process. Here are some key factors that determine the quality of biochar:

  1. Feedstock: The type of organic material used to produce biochar plays a significant role in its final properties. High-quality biochar is typically derived from clean, uncontaminated sources such as wood, agricultural residues, or dedicated energy crops. Low-quality biochar, on the other hand, may be produced from materials containing contaminants or high levels of ash, which can negatively impact its effectiveness in soil.
  2. Pyrolysis temperature: The temperature at which the organic material is heated during pyrolysis can affect the structure and properties of the resulting biochar. Higher temperatures generally yield biochar with higher carbon content, increased porosity, and greater stability in the soil. Lower temperatures may result in less stable biochar with lower carbon content.
  3. Processing and activation: High-quality biochar may be further processed to enhance its properties, such as activation with steam or chemical treatments. These processes can increase biochar’s surface area, making it more effective at retaining nutrients and water in the soil.

Current Trends in Biochar

There has been a surge in interest and research on biochar in recent years, driven by its potential to address various agricultural and environmental challenges. Some of the current trends in biochar include:

  1. The Magic of Biochar: A Sustainable Solution for Modern Landscape Management: Biochar’s ability to sequester carbon in the soil has garnered significant attention as a potential strategy for mitigating climate change. By locking away atmospheric carbon dioxide in a stable form, biochar can help reduce greenhouse gas emissions.
  2. Soil health and productivity: Biochar has been shown to improve soil fertility, increase water retention, and promote beneficial microbial activity. As a result, farmers and gardeners around the world are increasingly adopting biochar as a soil amendment to boost crop yields and enhance soil health.
  3. Waste management: The production of biochar can help address waste management challenges by converting agricultural, forestry, and other organic waste materials into a valuable soil amendment. This not only reduces waste volumes but also helps prevent the release of greenhouse gases from decomposing organic matter.
  4. Water and air pollution control: Biochar has been demonstrated to effectively remove pollutants from water and air, making it an attractive option for environmental remediation efforts. Its porous structure and large surface area enable biochar to adsorb contaminants, improving water and air quality.

Analysis of the Current Product Landscape for Biochar

As the demand for biochar grows, an increasing number of companies are entering the market to offer various biochar products. The current product landscape can be broadly categorized into the following segments:

  1. Raw biochar: This category includes biochar products that are sold in their most basic form, without any additional processing or additives. Raw biochar is typically marketed for use in agriculture, horticulture, and landscaping applications.
  2. Enhanced biochar: Some companies are offering biochar products that have been enhanced with additional nutrients, minerals, or microbial inoculants to improve their performance as soil amendments. These products are designed to provide added benefits, such as increased plant growth, improved nutrient availability, and enhanced soil biological activity.
  3. Customized biochar blends: To cater to the specific needs of various industries and applications, some companies offer customized biochar blends that combine biochar with other soil amendments, such as compost, peat, or vermiculite. These blends can be tailored to address specific soil conditions.

When to use a soil amendment versus fertilizer?

In the battle of soil amendments v. fertilizers, it’s important to note that these products serve different purposes in gardening and agriculture. The decision to use a soil amendment or a fertilizer depends on the specific needs and conditions of your soil and plants. Here’s a general guideline:

Soil Amendments

Soil Amendments: Soil amendments are substances added to improve the physical properties of the soil, such as its structure, drainage, water-holding capacity, and nutrient availability. They are usually used to enhance soil fertility in the long term and provide a favorable environment for plant growth. Common soil amendments include:

– Compost: Adds organic matter, improves soil structure, and enhances nutrient retention.
– Peat moss: Improves water-holding capacity and aeration in sandy soils.
– Vermiculite or perlite: Enhances soil drainage and aeration.
– Gypsum: Helps improve soil structure in heavy clay soils.

Soil amendments are particularly beneficial when dealing with poor-quality or degraded soils, as they gradually improve soil health and fertility over time.


Fertilizers: Fertilizers are substances containing essential plant nutrients that are added to the soil to provide immediate nutrition to plants. They are used to address specific nutrient deficiencies and promote healthy plant growth. Fertilizers come in different formulations, such as granular, liquid, or slow-release, and provide concentrated doses of specific nutrients, such as nitrogen (N), phosphorus (P), and potassium (K), as well as micronutrients.

Fertilizers are typically used when plants exhibit signs of nutrient deficiencies, such as yellowing leaves or stunted growth. They are also useful during periods of rapid growth or high nutrient demand, such as flowering or fruiting stages. Fertilizers provide quick results, but excessive or improper use can lead to nutrient imbalances, environmental pollution, or damage to plants.

In summary, use soil amendments when you want to improve overall soil quality and long-term fertility, while fertilizers are suitable for addressing immediate nutrient deficiencies or promoting vigorous growth during specific plant stages. It’s essential to assess your soil’s condition, perform soil tests to identify deficiencies, and consider the specific needs of your plants before deciding whether to use a soil amendment or a fertilizer.
