About Bloom City Professional Grade Ultra Pure Cal-Mag Growing Fertilizer
88% highlighted the application frequency
The fertilizer helped me increase the blooms and new tomatoes while eliminating the blossom end rot.
I was worried about the application of the fertilizer once the fruit had developed, but it worked and the blossom end rot stopped immediately.
A quart bottle of fertilizer can treat a good sized garden for several years if used for treating tomatoes like I do in my garden.
92% appreciated the user-friendliness
I found the fertilizer easy to use and effective. I used it once a week and it worked well. I still used organic miracle grow every other week but had the best production of veggies in a few years considering the weather.
I found it easy to apply the fertilizer by adding a capful to a watering pail of H2O and sprinkling it liberally over the leaves.
93% liked the solubility
The liquid fertilizer absorbs quickly and doesn't have unnecessary nitrogen for mid-season use.
After pouring the quarter-strength mixture through the potting mix, my leaves had greened up the next day.
