Micro-Boost is a micronutrient blend specifically designed to improve the yield potential of your vegetable garden plants by maximizing nutrient uptake, promoting a robust root system and an overall healthier plant. Can be used on all crops.


Micro Boost is a garden supplement that provides the appropriate quantities of essential micronutrients to maximize your vegetable garden harvests. This is a liquid formulation that includes essential micronutrients like Magnesium, Sulfur, Boron, Iron and several others. Use it alone or add it to your favorite balanced fertilizer formulation. It works great in our EZ-FLO Fertilizer Injector, but can also be mixed in a watering can or pump sprayer. Just apply 1/4 cup of Micro Boost per 1,000 sq. ft. for best results.

Magnesium is an essential micronutrient that helps to give leaves their green color. It is the central molecule in the chlorophyll molecule and thus helps chlorophyll to capture the suns energy for photosynthesis to occur. Sulfur is a key component of plant proteins and helps the plant to use available nitrogen in the soil. Boron is an important micronutrient for sugar transport within the plant, and is a very helpful micronutrient when growing beets. Copper is necessary for plant respiration and improves flavor and color in vegetables. Iron is one of the most essential micronutrients because it is involved in pigment formation and energy production within the plant.

Micro-Boost Supplement Includes:

  • Magnesium (Mg) - 1%
  • Sulfur (S) - 3.5%
  • Boron (B) - 0.2%
  • Copper (Cu) - 0.5%
  • Iron (Fe) - 2%
  • Manganese (Mn) - 2%
  • Molybdenum (Mo) - 0.003%
  • Zinc (Zn) - 0.75%

Usage Instructions:

Beans: Apply 1/2 cup per 1,000 sq. ft. 7-10 days before bloom, and again at full bloom.

Sweet Corn: Apply 1/2 cup per 1,000 sq. ft. once corn plants have their third leaf. Apply weekly up until the silking process.

Other Vegetables: Apply 1/2 cup per 1,000 sq. ft. per week 7-10 days after transplanting. If direct seeding, being weekly applications once plants have their second set of true leaves.

This stuff works!

I ran across this stuff on Amazon. I have a degree in agronomy. I have always sprayed different micronutrient blends on a number of different cool season grasses and it most definitely works on that aspect. I was looking for something for my veggie garden. Most big box store fertilizer either organic or not does not have micronutrients or not that many in them as this product does. I could not believe the results. I live in minnesota. We had one of the hottest and driest years on record this summer (2023). I have never grown bigger tomato, cucumber, squash, etc vegetables in my life. Leaves were dark green, healthy, no disease. I trellis my tomatoes and cucumbers. At 7 feet tall, they fell over and continued to grow. The yield was insane, just crazy. Fertilizer is great but plants need micronutrients. I'm glad I found this product. I'll be buying it as long as they make it.


Works well noticed a big boost on my cabbage and broccoli in a week!


Great product, greater people.

I started using Micro-Boost a year ago and have been blown away with how well my veggies (especially tomatoes and corn) seem to like it! Big difference in productivity and size of tomatoes! It's a given that I will not be without Micro-Boost from here on out! I consider it a staple for my garden!
