GreenCure has made a huge difference, My garden was getting gradually worse with blight and blossom end rot. I now have tomatoes better looking than ever and I have beaten the battle of blossom end rot on my zucchini and tomatoes by using Epsom salts. I am not completely rid of blight but it is definitely more manageable. I would definitely buy GreenCure again.

This stuff works great! A friend told me I needed a smudge pot to control the mold on my greenhouse veggies. I didn't like the idea of all that sulfur. I sprayed everything once, then ONLY when I saw any new mold growth. This product is great!

Each year I seem to battle a form of tomato blight where the plants turn yellow, brown and then die too early. I have tried many remedies, sprays and the advice of many garden "experts" with very mixed results. Until Green Cur e! I sprayed every week or two. The product is aptly named: Green CURE. This product delivers.

It is the only product that I have used that will control Powdery Mildew on my Re Maples.

I sprayed greencure in my garden and all the pm went away, two weeks later the pm was back and I sprayed again and it was gone. So overall greencure does what they say it does. Greencure is my new best friend. I am very happy with this product I will need more soon. Thanks
