Our #21 concentrate fertilizer is a great way to dilute the proper amount needed for fertilizing plants. Just squeeze 1/2 ounce of concentrate into 1 gallon of water and use.
Imagine no messy mixing and staining of your fingers, no need to find a tablespoon that usually gets lost and the correct rate needed for all your plants from a “squeeze and pour” reusable/refillable. A few years ago my wife told me that she was done messing everything with the normal crystals found today. This is the same fertilizer we use inside the greenhouse to grow our plants.
This blend is perfect for maintaining a strong plant while reducing the unwanted “leggy” growth associated with high phosphorus fertilizers (the middle number in fertilizer analysis) and promoting healthy blossoms. It is perfect for annuals and perennial in ground beds and all pots/hanging baskets. Use this fertilizer weekly when night temperatures are above 60 degrees.
This blend can be used on supertunia/calibrachoa plants in pots and hanging baskets but a better choice is our Extra Iron blend below.
