Worked great.
Had some maple trees that are prone to iron deficiency. Got this so I could solubilize it and apply to the roots. Couldn't see exactly how much, wrote the company an e-mail and heard back the next day with specific amounts and instructions. Amazing! Pretty rare to get that kind of corporate response. Best of all, my trees snapped right back (about 3 weeks). Apply once a month and they just keep getting more and more green. Will definitely buy again to start applying next spring. Saved my trees lives, literally.

Your tomatoes and other KINDs of plants will love it!
2023 has been a brutal year for my garden. The rains of winter gave rise to swarms of insatiable insects, some of which I had never seen before. Then, we had record temps that turned many of my plants into crispy critters no matter how much I watered them.The few tomato plants that didn't wilt into oblivion then developed BLOSSOM END ROT! Knowing that BER is often caused by a lack of calcium, I ordered this product. Unlike traditional garden Epsom salt, this Humboldt formulation also includes magnesium, which helps the plant absorb more calcium, along with iron. I gave it to my tomatoes and within a week, blossom end rot stop being a thing. I also used it on my "other" types of plants that are legal in many places. They LOVED it! I am now trying on my trees and hoping Humboldt's Secret will help them endure what I hope are the last few days of scorching temps.
