Plant Catalyst


# Like all living beings, plants get their nutrients through cells, and their ability to grow and flourish is directly tied to cellular absorption, retention, and utilization of nutrients. Gardeners and professional growers have been using Dr. Willard’s Water® products to enhance cellular absorption of nutrients for nearly 40 years. These growers have found that using Dr. Willard’s on plants will help stimulate plant health, growth, and yield with spectacular results. We developed Dr. Willard’s Plant Catalyst ® specifically for use on plants and PlantCatalyst® is the only Dr. Willard’s product specifically designed and government approved for use on plants.
The potential impact of Dr. Willard’s PlantCatalyst® on plants, even in very dilute solutions, was first identified in one of Dr. Willard’s first published experiments conducted in a commercial greenhouse. He and Dean Sime, owner of the Jolly Lane Greenhouse in Rapid City, South Dakota, added one ounce (30 ml) of Plant Catalyst® to 4.000 litre (1,000 US gallons) reservoir and reduced Sime’s standard nutrient application by 50% (see Roy Jacobsen, Aqua Vitae, 1992, pages 69-71). Sime’s testimony in a video also entitled, Aqua Vitae, mentions improvements in seed germination, sturdier stocks, more blooms and more buds (see also Jacobsen, pages 69-71).
The results of that experiment have been supported in subsequent years by test data on over 100,000 plants in commercial greenhouses in Florida, Ontario and British Columbia and studies at institutions such as the University of Wisconsin and South Dakota State University, among others. Many of the studies can be viewed by visiting the research tab on our Plant Catalyst® website.
Like all Dr. Willard’s Water® products, the precise mechanism behind how Plant Catalyst® actually operates within the plants’ cells remains a mystery, but the reported impact on plants is well documented and fairly extensive.

Benefits of using Dr. Willard’s PlantCatalyst® include:

  • Larger and/or greener plants.
  • More blooms and/or plants blooming earlier.
  • Sturdier stocks and/or more extensive root systems.
  • Greater resilience in stressful growing environments.
  • More yield per plant, larger fruit/flowers and enhanced flavour and aroma.

PlantCatalyst® and other Dr. Willard® products have been tested and analyzed by many reputable laboratories, universities and commercial greenhouse owners/operators around the world. This testing with plants, animals, and humans demonstrates the enhanced cellular absorption and nutrient retention features of these unique products.


# Prior to planting, soak or spray seeds, using a mixture of 30ml (one ounce) of PlantCatalyst® to one 4 liters (one US gallon) of water. If using rock wool cubes, use this mixture to soak your cubes prior to seeding. You can also use this mixture to soak cuttings prior to planting. Spray seeds/cuttings with this mixture daily throughout the germination stage.
In the reservoir, add 60ml (two fluid ounces) of Plant Catalyst ® per every 200 liters (50 US gallons) of water. Plant Catalyst® can be combined with any nutrient formula, but watch your plants closely for any signs if they’re getting too many nutrients and reduce nutrient levels accordingly.
Plant Catalyst ® should also be added to your regular foliar spray routine. For manual operations or smaller crops, mix 15 ml of Plant Catalyst ® per liter of water and spray a light mist on your plants. For automated systems or later crops, use the rate recommended for reservoir application above. Dr.Willard’s PlantCatalyst® should be added to any foliar feed application to increase absorption and effectiveness. readmore


If feasible, prior to planting, soak seeds overnight in a Plant Catalyst ® solution comprised of one ounce of PlantCatalyst® added to one gallon of water.
If using a pre-planting treatment to hasten seed germination, add 60ml (two fl. ounces) of PlantCatalyst® per 200 liters ( 50 US gallons) of water/treatment solution and apply as directed. For use with a liquid fertilizer as a side dressing, mix 90 ml (three fl. ounces) approx. of PlantCatalyst® per 200 liters ( 50 US gallons) of water/fertilizer solution.

The fertilizer solution should contain ½ the amount of fertilizer ordinarily used.
When spraying grain and forage crops as a foliar treatment use 60ml (two fl. ounces) of PlantCatalyst® per 400 liters (100 US gallons) of water and spray at a rate of ten gallons per acre.
