Masterblend 9-12-34 strawberry formula is well-suited for for both soil based and hydroponic strawberry growing. Ideal for growing strawberries! As with all of Masterblend water-soluble fertilizers, our 9-12-34 completely dissolves in water with no fallout and won’t clog sprayers or automated fertilizer delivery systems.

It is recommended to use this product with Calcium Nitrate and Magnesium Sulfate (Epsom Salt) in the following recipe. Please note using a scale is the most accurate way
to measure, and volume measurements are only approximations:

5 Gallon Recipe:
Add 8.5 grams MasterBlend Strawberry Formula (aprx 1.5 tsp) to 5 Gallons of water. Add 5.6 grams (aprx < 2 tsp) of Magnesium Sulfate (Epsom Salt) and mix completely. Next, add 8.5 grams Calcium Nitrate (aprx 1.5tsp) and disolve. Adjust pH after nutrients are dissolved in solution.

For Soil:
Apply 1 quart per square ft. as a normal watering on a 1-2 week basis. Hydroponics: use as a constant feed.

For Transplants:
Mix 5.5 grams with water, then add 3.5 grams Epsom Salt, then 5.5 grams Calcium Nitrate. Use every other watering.

For larger/smaller amounts, multiply or divide the 5 gallon recipe above to your needs.
