Frequently Asked Questions:
Q: WHAT IS HUMIC ACID?
A: A naturally occurring substance from decomposed organic matter that revitalizes soil and supercharges nutrient absorption.
Q: Why is it called "Humic Acid"? Is it dangerous?
A: Great question—the word “acid” in “humic acid” sounds stronger than it really is. But don’t worry—this is not a harsh chemical like battery acid or vinegar.
Humic acid is a completely natural substance that comes from ancient organic matter (like decomposed plants) found in the earth. It’s called an “acid” because of its chemical classification, not because it’s corrosive or harmful. In fact, it’s safe for all plants, pets, and people when used as directed.
Think of it like vitamin C for your soil—it helps unlock nutrients and feed the living biology in the ground that your plants need to thrive. Many organic gardeners and farmers use it regularly to improve soil health and boost plant growth—safely and effectively.
Q: What is is Humic good for?
A: Plants only absorb a fraction of the fertilizer you apply. The rest is often locked in the soil—or washes away. Humic Acid changes that. It binds nutrients in a form that roots can absorb, naturally enhancing fertilizer efficiency and soil vitality
Q: Is this product safe for pets and kids?
A: Yes! Our humic acid is 100% organic and derived from natural sources. It contains no harmful chemicals and is safe when used as directed around pets, children, and edible plants.
Q: How often should I apply it?
A: For most plants, apply once per month during the growing season. For problem soils or heavy feeders, apply every 2–3 weeks.
Q: Can I mix it with other fertilizers?
A: Absolutely. Humic acid actually improves the efficiency of other fertilizers, helping your plants absorb more nutrients with less waste.
Q: What does it do for my soil?
A: It improves soil structure, boosts microbial life, and enhances the availability of nutrients—creating a healthier, more productive growing environment.
Q: Is this just for outdoor use?
A: Nope! It's great for indoor potted plants, too. Just dilute and apply to the soil like you would outdoors.
Humic acid is a natural organic compound that is derived from the decomposition of organic matter. It is commonly used as a soil amendment to improve soil structure, nutrient availability, and overall plant health. Several types of plants can benefit from the application of humic acid, including:
Vegetables: Humic acid can be beneficial for a wide range of vegetables, such as tomatoes, peppers, cucumbers, carrots, lettuce, and many others. It helps with nutrient uptake, leading to better growth and higher yields.
Fruits: Fruit-bearing plants like strawberries, blueberries, grapes, citrus trees, and apple trees can benefit from humic acid. It promotes healthy root systems and can enhance the flavor and quality of the fruits.
Herbs: Culinary and medicinal herbs, such as basil, mint, rosemary, and chamomile, can thrive with the help of humic acid, as it supports their nutrient absorption and overall growth.
Ornamental Plants: Flowers and ornamental plants, including roses, lilies, petunias, and others, can have improved root development and increased resistance to stress when treated with humic acid.
Lawns: Applying humic acid to lawns can enhance soil fertility, improve grass health, and increase the lawn's ability to withstand drought and disease.
Shrubs and Trees: Landscape shrubs and trees, such as azaleas, rhododendrons, and various ornamental trees, can benefit from the use of humic acid to support their growth and development.
Crops: A wide variety of field crops, such as corn, wheat, soybeans, and cotton, can experience improved nutrient uptake and better soil structure with the application of humic acid.
What Our Customers Are Saying
Thank you so much for Orchid Love. I bought mine on Amazon.com. I have been using it for the last five months. My orchids haven't looked better. Then I discovered a secret using your Orchid food. I have been dripping it down the old spikes of my 14 orchids not in flower for the last month. Now I have 5 of my orchids sending up new spikes that should be blooming around Christmas and 3 shooting secondary spikes off the old spikes. Even my other house plants love it. Thank you so much.
— Mary Yarwood
I received this product in a very timely manner. After the first application this seems to be working on my fall garden in zone 7. The lettuce, cauliflower, and broccoli all responded to a foliar spray of 1 Tbsp mixed in a half gallon of water. I also applied it to my tomato plants that had slowed down due to the colder weather and was surprised to see all of the plants start setting new blooms and fruit. I was at the point of actually pulling the tomato plants out for the year but look to maybe get a few more tomato's off each plant now!
— Theman
Hi, just received your kelp and humic acid per Amazon.I scoped them at 40 and 100x shortly after opening and could not believe the diversity compared to a competitor's similar products.I provide the most thorough organic lawn/soil treatments in the Gainesville Fl area, and looking forward to continuing business."Thanks for your product
— Chad Freeman
So far, my plants and microgreens seem to respond well--new growth and deeper color--to the spray I mixed with water and store in the refrigerator.
— Greenpinky
My only complaint is that the bottle could be designed better so that the liquid doesn't drip everywhere and get a little messy even when using a funnel to catch extra liquid.
It smells strong & stains, so prepare your mixture outside or on a plastic covered table.

FAQs
Please read our FAQs page to find out more.
Why do organic fertilizers like yours have lower NPK values than synthetic fertilizers?
Synthetic fertilizers artificially spike NPK levels far beyond natural amounts, much like vitamin pills overload the body with nutrients it can’t fully absorb. Organic fertilizers, however, workwithnature—enhancing plants’ ability to uptake nutrients efficiently without excess runoff. This means lower NPK numbers deliverhigher effectivenesswhile protecting ecosystems from pollution caused by synthetic waste.
How should I store your products to maximize shelf life?
Store products in a cool, dry place away from direct sunlight and extreme temperatures. Ensure lids are tightly sealed after use. While most formulas have an indefinite shelf life, always mix only what you need for immediate use to maintain potency.
Do I need to water my lawn after applying your liquid fertilizers?
No watering is required! Our liquid formulas absorb quickly into the soil. For best results, apply early in the morning to allow 2-3 hours of soaking time before rain or irrigation. This ensures maximum nutrient retention without runoff.
Is it safe to harvest vegetables right after using your products?
Yes! Most of our products have a zero-harvest interval, meaning you can pick produce immediately. However, we recommend waiting 2-3 days after application for optimal nutrient absorption and flavor development.
How do organic fertilizers reduce environmental harm compared to synthetics?
Synthetic fertilizers overload plants with nutrients they can’t fully absorb, leading to harmful runoff that pollutes waterways. Organic formulas, like ours, mimic nature—delivering balanced, bioavailable nutrients that plants use efficiently. Think of it as feeding your garden a wholesome meal instead of forcing it to “overeat” synthetic additives.
