Description

Our specialized formula uses activated humics to enhance your soil, increasing microbial activity and nutrient availability to keep plants healthy. Many gardens have nutrient-depleted soil making it difficult to support healthy plants. Our revitalizer invigorates soil to help plants thrive. Feed the soil, not the plants! The best way to avoid pests and diseases is to ensure your soil is nutrient-rich, leading to strong, healthy plants. Dilute with water and use a watering can for root application or a sprayer applicator for foliar feed. What plants do I use this on? Improving soil health is universally important, so this product benefits anything that grows and works on any soil. Use across your garden and lawn. Also great for trees, turf, houseplants—and even as a liquid aerator. What is this made out of? The primary active ingredient in the product is activated humics derived from brown coal (decomposed matter). Humics are naturally occurring substance that can do wonders for soil and plant health. Is it organic? Yes! This product is OMRI certified, derived from only organic substances. Is it safe to apply where kids and pets will be around? Yes, as long as you dilute the product with water as directed, areas you apply the product to will not pose any harm to kids or pets! What makes this better than competitors' products? The secret is activated humic technology. Activated humics outperform regular humics by being more soluble and bioavailable, enhancing nutrient uptake, improving soil structure, and boosting microbial activity—leading to healthier soil and plants. I’m a beginner, is this hard to use? No! This is a great place to start if you’re on the beginning of your gardening journey. There's no risk it will harm your plants if you dilute it properly and it’s very easy to use. What is the mixing ratio? Mix 1 oz of Soil Revitalizer per 1 gallon of water When and how often should it be applied? Every 2-4 weeks throughout the growing season. Most critical times are in the early spring and late fall as these will lay a great foundation for a super successful growing season. Where is it made? All of our products are made in the USA and the majority of our blending and bottling is done in Kentucky! Does it expire? What about once it’s opened? Practically speaking, no. It has a shelf life of 10 years, so if you’re so inclined, feel free to order a decade’s worth today. Opening it will not impact that. How does it help with disease resistance? What can humans do to help prevent getting sick? Eat nutritious foods, minimize stress, etc. It’s the same with plants! A healthy soil medium is the best thing to increase your plants' health. If I use it on fruits and vegetables, will they be safe to eat? Yes absolutely. Everything in our product is from naturally occurring substances that are already present in the soil and being used by your plant. There is nothing in the product that plants (and humans) don’t consume on an everyday basis. How do I apply? This product can be used with a watering can, hose end sprayer, irrigation system, etc. It can also be mixed and applied together with fertilizers, insecticides, herbicides, etc Can I use this on indoor plants? Absolutely. For houseplants, around a tablespoon per plant is all you’ll need (diluted into at least a cup of water). How quickly will I see results? This is not a traditional synthetic "NPK" fertilizer, because of that, the immediate results will be more subtle. This product has an impact similar to composting, improving soil health and nutrient availability over the long term. Our formulas are used by farmers to increase crop yield all over the country (and the world!). PhD agronomists develop our formulas for their intended use case We perfect our formulas and ensure efficacy by using controlled tests both in our lab and outdoors in real growing conditions We test different concentrations and feeding schedules to make sure you get the best results for your plants Just check out some of the amazing results our customers have gotten over the years (including some award winning plants!)

  • Does help potted plants in older soil, but can be expensive to use. Does help potted plants in older soil, but can be expensive to use.
Size: 8oz
I have been growing almost all of our veggies and herbs indoors in our basement, year around, for over 10 years. Some of these plants, generally grown as annuals outdoors, can continue to grow and produce for over 5 years or more indoors. Even though I provide the appropriate fertilizers for my plants, the health of the soils is essential for these nutrients to be utilized. Since the older plants are in the same pot with the same soil for quite a few years, I decided to try this soil revitalizer on some of my older plants. Humic acid works in a similar way to compost, but compost takes time to break down to provide its benefits and can rob your plants nutrients during decomposition. . In addition, compost can change the PH of your soil. Whereas, humic acid is PH neutral. Humic acid can be thought of as a decomposed compost that will help plants to uptake minerals in the soil. Even if your soil has over-accumulated certain minerals, humic acid will help them grow well regardless. Another advantage of using humic acid rather than compost is that it can be added to water to provide immediate benefits. This can be helpful for established plants, such as mine, when trying to add compost would be almost impossible and benefits would be negligible. Although this soil revitalizer has been beneficial to my older plants, I did notice the ingredients of the product which state 2% humic acid and 98% water. It seems that this product would be much less expensive to use if the ratio of humic acid was increased with less water. If someone wanted to improve the soil on 5 acres of land, according to the label, 43 gallons of this product would be required for one application. This would be a cost, at current pricing, of $1719.57. Granted, most of us don't want to condition 5 acres of soil, but increasing the percentage of humic acid to the percentage of water would greatly decrease the cost of using this product. As it is, the recommend dose for watering is 2 ounces per gallon of water. So, the 8 ounce bottle would be good for 4 gallons of water. Since some of my larger pots require 4 gallons of water for every watering, this product is very expensive for me to use. Even for my application for use on older plants grown indoors, use of this product can be costly when considering the costs of fertilizers that are still required. I hope this review was helpful for you. ... show more

I was officially done battling rock-hard, lifeless soil after pulling 20-year-old shrubs. Enter this soil revitalizer. Two treatments later, my dirt went from clumpy misery to soft, workable heaven. My plants look greener. Easy to use, no weird surprises. I’m cautiously optimistic—and no longer personally offended by my garden. Honestly, it saved my gardening sanity. ... show more

  • Best thing for your plants!
Size: 32oz
This stuff really works! We had landscaping fabric over our beds for 20 years. When we moved to our house, nothing would live because the landscaping fabric killed the soil and we have clay soil so it worsened matters. We ripped everything up, planted everything new and I applied this and the plants are doing amazing! I re-applied recently and you can already see new growth and happy plants. I didn’t notice any smell. I applied with a watering can per the directions. The bottle is small but it goes such a long way. ... show more

  • This one is not better than small bottle. Buying revive one.
Size: 32oz
The small volume was working better. This one seems more like knock off or lower quality product than that small bottle. Also why on this earth you design seal cap such a bad ways. Why can’t be a smart narrow easy to pour a few drop by drop type or more controllable no spill container. It’s terrible to remove the seal and then when pouring it mostly spill or drop too much or spill specially if I am using a bottle water to add this. Or give cap with a dropper so one can measure and drop without spill. Since this big container is not that good quality so in future going to buy revive brand one only. ... show more

Def a day and night type of situation, I have a few plants that just couldnt get them to properly absorb nitrogen, I tried ph n the water, nutrients, etc, the did get better but not the green I wanted. So I got this to balance all the nutrients, and like I said day and night results. I woke up to the results I wanted, Just bit bigger plants but the green is starting to come through ... love it... dont feel that you need to do it more than one time in a good while, but for now to get the soil activated, and corrected, this def did the job. ... show more
