Saved my jalapenos from blossom end rot
I started growing jalapenos for the first time in 2025 and many started out with blossom end rot and I thought I was going to lose a lot of the future harvest. I did some research and found this product that helped keep them healthy. I ended up harvesting well over 1000 jalapenos from about 20 plants. I liked this one because it's a liquid and can easily mix into my watering regime. Others I found were like granules/pellets and I felt would not be as effective. I still have a lot left over and will absolutely purchase more when I run out. Keep your harvest healthy!
