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%

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.

Ah my secret sauce, my Sandy soil is poor in the elements in this boost, I always add a cup or two in my injector with the 20/20/20

Happy Florida grower

I've been using micro boost every 14 days on my to tomatoes peppers and cucumbers. And liquid 10-10-10 every 7 t0 8 th day. My shelby, red snapper and hossinator tomatoes and full of tomatoes that there pulling the 2×2 steaks over. Had to do a Florida weave just to keep them up straight. Probably getting 50+ pound of tomato every 3 days off of only 30 total plants for last few weeks. The salsa is delicious, canned over 150 pints to last the year, Love all the hoss products.

I've used Micro-Boost for a few years. This product really does work. I use it primarily in the Hoss Fertilizer Injector, another really good product!

It seems to make my plants healthier, it took a day or so before I saw results, but I can tell a difference in them.
