Bonide Rot-Stop Tomato Blossom End Rot, 32 oz Ready-to-Use Spray Garden Fertilizer for Calcium Deficiency in Plants

THE BEST PRODUCT FOR TOMATO PLANTS!!

I am so pleased with this product! It allowed me to enjoy tomatoes by nourishing the plants producing rotten ones to stop doing that! I will warn that it is so important to not overkill applying---it mentions applying until it runs off. I think that is a little too much. It makes the plants burn from the sun easy and scaled them back a bit before they grew back. I would just apply enough to spray in each section and then stop--do not keep spraying until run off--they will burn! I have only had to apply once or twice to each plant affected this season, not every week.

Does work well, takes several coatings.

Suggest buy the concentrate only use 2 once to gallon. As Cheaper just Get spray bottle from dollar store. Spray liberally soak the plant and fruit. Note if rot has started will not reverse (u can cut away bad area to salvage good) but new tomatoes will be good. I spray every 5 days. Next year crop mix calcium or nutrients at planting time I use Dr. Earth tomato & vegetable fertilizer but many others brands I also add egg shells crumpled from my cooking during growing season as calcium.

Either the formula changed or the way it was stored was impromper. I saw negative comments about it killing peoples plants. Nieve me assumed they had done something wrong with the application. I have used this exact product for many years purchased from a different supplier and never had an issue. As a matter of fact it has SAVED my garden with each use. However, this product ordered via Amazon killed everything it touched. Even the overspray that got on plants behind the treated plant burned up where ever the mist hit. It was literally like I poured pure acid on my plants. It scorched the leaves and stems over night and by the end of the next day the fruit was shriveled up and scorched on the sides that were exposed to the spray. I leveled my ENTIRE garden over night by using this horrible product. I wish they would replace the huuuuuundreds of dollars and even more in hours spent getting the garden to the point it was at before this $10 product murdered everything it touched. To say we are disappointed is an understatement!!! To further prove it was the product, I cut off all the parts that were decayed from the product, heavily rinsed every plant with the hose and let them just sit where they were and miraculously just now in freaking August they have new green growth. Its in vain though as we live in Michigan and wont have enough season left to get viable fruit. I used to rave about this product and since I don't know if its the manufacturer or the warehouse that lead to this I will no longer sing it's praises. If you make the mistake of buying this and from here on amazon, do a test plant before you murder everything you love...

Still had some issues with blossom rot after using

This works well, but make sure you read and follow the instructions.

Last year tomatoes I had a lot of bottom rot. I sprayed them several times this summer, I am picking tomatoes now no rot.
