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

I was disappointed with seeing End Rot on my plants since I felt that I had done everything right with planting my tomato plants but there it was. I researched my options for treating it and this was highly recommended. I honestly had my doubts, a spray to fix a calcium issue, but it was absolutely effective with only one use.......WOW!! The value was worth every penny because I only lost the first tomato that I saw with it. The size was worth the price, great value. I didn't pay attention to the plant growth since I did not purchase this product for growth but I would have to say, my plants grew taller than expected and absolutely beautiful tomatoes.

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.

Even though I always use bone meal, fertilizer, and/or compost, one of my potted tomato plants was churning out nothing but tomatoes with blossom end rot. Sometimes the balance is off where a plant just has trouble absorbing nutrients through its roots, and amending the soil just doesn't seem to work in a timely fashion. After all, a plant only has so much time to put out new fruit for the season and it is too late to start a new plant. I bought this hoping that a foliar spray might work. I tried it out, making sure that it was in the early evening, so it wouldn't burn the foliage. It worked really well. Within just one week, all of my new ripening tomatoes are coming out just fine now. The spray bottle didn't leak or clog, like many on the market annoyingly do. The only gripe I have was that it wasn't shipped on time. I wanted it right away, so I specifically looked for a product with next day delivery. I didn't have a lot of time to waste. When it didn't arrive on time, I ended up going to Farm and Fleet about a half hour away to purchase the same brand. That was very annoying. The only thing available at the store was the concentrated form. It turned out to be much more economical. Next time, I will just skip the Amazon purchase and buy this locally.

It works!!! No leakage and was bagged in case it did leak. I waited until sunset out of 10 tomato plants only one seemed to have a burn or ill effect. Leaves curled the next morning. Sprinkled some water over it. Came out of it 2 days later. My tomatoes definitely look better!!

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

Worked very quickly on my bottom rot and didn't need reapplied for rest of season.

Works really well for treating end rot on our tomato plants. Easy to use.
