Review: A+ - Works as described. Could not go wrong with masterblend.
Review: Really made a difference - I used Masterblend for the first time this 2025 growing season on my tomato and pepper plants. I did not use the other recommended products along with it and was diligent in keeping with a fertilizer schedule. Although the weather was either brutally hot with temps of 90 to 98 day and night for several weeks or drizzly and cold early on, after an initial blossom drop, the plants produced bumper crops. Easy to use and economical due to the small amount that is needed.
