Wyoming Hemp Company | The Future of Hemp
Growing healthy, flavorful herbs starts with the soil and everything you put on top of it. Whether you tend basil, rosemary, parsley, cilantro, or specialty medicinal herbs, three things drive success: steady moisture, low weed pressure, and living, healthy soil. Hemp Guard Mulch helps you deliver all three, without synthetic materials or harsh chemicals.
Below, we answer the questions herb growers ask us most.
What Is Hemp Guard Mulch?
Hemp Guard Mulch is a natural mulch made from 100 percent industrial hemp and milled right here in Hawk Springs, Wyoming. It is designed to protect plants and build soil while supporting sustainable gardening. There are no synthetic additives, no dyes, and no harsh chemicals. Because it is plant-based, Hemp Guard breaks down naturally and works with your soil rather than against it.
Is Hemp Guard Mulch Safe for Herbs?
Yes. Hemp Guard Mulch is a safe choice for herb gardens because it is made from a single natural ingredient with no synthetic additives or dyes. Many conventional landscape products rely on dyes or chemical treatments that gardeners would rather avoid on edible and medicinal plants. Hemp Guard contains none of those, which makes it well suited for herbs you plan to harvest for the kitchen, the tea cabinet, or the apothecary shelf.
Research on mulching in medicinal and aromatic crops supports the broader point: a clean organic mulch layer can improve growing conditions and even enhance harvest quality. Reviews of these cropping systems report that mulch improves soil moisture retention, regulates soil temperature, and can support the quantity and quality of essential oils and herbal raw material (Horticulturae, 2025).
How Does Hemp Guard Help Herbs Retain Moisture?
Hemp Guard works as a protective blanket over the soil surface, slowing the rate at which water evaporates. That keeps moisture in the root zone longer between waterings.
Decades of mulching research back this up. University extension specialists note that mulch reduces evaporation from the soil surface and helps soil hold water, which keeps moisture levels more consistent for root growth and nutrient uptake (University of Minnesota Extension, 2026). Peer-reviewed reviews of organic mulching report the same effect, finding that mulch enhances soil moisture retention by reducing evaporation and improving water infiltration, with the strongest benefits in hot, dry, and water-limited conditions (Singh & Chamroy, 2025).
For herb growers in Wyoming and across the High Plains, that matters most during summer heat and in raised beds and containers, where soil dries out fast.
Does Hemp Mulch Suppress Weeds?
Yes. By covering the soil surface, Hemp Guard blocks the sunlight weed seeds need to sprout, which naturally reduces weed pressure and cuts down on hand weeding.
This is one of the most consistent findings in mulch science. Extension research explains that mulch limits weed emergence primarily by blocking light at the soil surface, making it harder for weeds to germinate and establish (University of Minnesota Extension, n.d.). Review studies add that organic mulches are most effective against annual broadleaf weeds and small-seeded species, the very weeds that crowd herb beds (Singh & Chamroy, 2025). Fewer weeds means less competition for water, nutrients, and light, so your herbs can put their energy into healthy, flavorful growth.
Why Is Hemp a More Sustainable Mulch Choice?
Choosing Hemp Guard does more than help your herb garden. It helps reduce reliance on tree-based mulch products and supports American farmers committed to regenerative, sustainable agriculture.
Industrial hemp is a fast-growing, renewable crop, and a comprehensive literature review on its economic, environmental, and social sustainability identifies biodegradable mulch as an established use of hemp fiber (Kaur & Kander, 2023). As an organic mulch, Hemp Guard continues to deliver benefits after it is applied. Extension specialists note that organic mulches break down over time, slowly releasing nutrients and improving soil structure as they decompose (South Dakota State University Extension, 2025). In other words, it feeds your soil on the way out.
A note on honesty, because it matters to us: the science on mulching in general is deep and well established, while peer-reviewed research specific to hemp mulch is still emerging. We will always tell you what is well documented, what is promising, and what comes from the real-world experience of growers using our product. No greenwashing, ever.
How Do You Use Hemp Guard Mulch in an Herb Garden?
Hemp Guard works in backyard herb gardens, raised beds, patio containers, and larger herb production alike. Apply an even layer over the soil surface around your plants, keeping it slightly away from stems to allow airflow. Refresh as it breaks down through the season. By helping retain moisture, suppress weeds, and build soil over time, Hemp Guard creates an environment where herbs thrive.
Frequently Asked Questions
Can I use hemp mulch around edible herbs? Yes. Hemp Guard Mulch is 100 percent industrial hemp, with no dyes or synthetic additives, making it a clean choice for edible and medicinal herbs.
Will hemp mulch attract pests or grow weeds? Hemp Guard is milled from clean industrial hemp and works by blocking light to suppress weed germination (University of Minnesota Extension, n.d.). It is not a seed source, so it does not introduce new weeds the way some low-quality mulches can.
Does hemp mulch contain THC or anything intoxicating? No. Hemp Guard is made from industrial hemp grown for fiber, which contains only negligible THC and is cultivated under federal and state regulatory programs.
How is hemp mulch different from wood mulch? Hemp is a renewable annual crop rather than a tree-based product, and hemp fiber is recognized as a biodegradable mulch material (Kaur & Kander, 2023). Choosing it helps reduce reliance on tree-based mulch.
Is hemp mulch good for raised beds and containers? Yes, and these are where it shines. Raised beds and containers dry out quickly, and mulch reduces surface evaporation to keep moisture more consistent (Singh & Chamroy, 2025).
