Calcium Nitrate 15.5-0-0 Fertilizer - Made in USA - 5LB Greenhouse Grade Plant Food for Hydroponics, Plants & Gardens – Fruit, Vegetables. Blossom End Rot Tomatoes

Does a good job

I kid you not, I put this in *all* of my plants. Everything. My orchids and roses love this stuff. Mix it into your soil or dissolve some granules in water to feed your orchids. I recommend this to anyone on my gardening Facebook group who talks about using egg shells.

I was experiencing bloom rot with all of my potted tomato plants this past summer. After doing research on the cause, I discovered that the plants needed Calcium Nitrate. I bought this bag of Calcium and added some several times to the soil over the summer, and the bloom rot disappeared. I will be using this from now on every time I plant a tomato!

Solved my tomato end blossom rot !!

I planted some tomato plants in 5 gallon buckets and was getting blossom end rot. I worked so hard on these things and to have that happening was so distressing. Come to find out, because they were in buckets, and the buckets had drain holes, they are susceptible to this condition due to low calcium levels. I used this - first I sprayed some on the leaves and plant which is the way to get it a 'quick' response, and then I also watered it as directed with the calcium. Within 1.5 weeks, I did not see any more end rot, and even months later after re-applying this, still producing lots of tomatos. One bag will take you a long way in a use case like this, so its totally worth it.

Good seller

Just fine

This saved my tomato plants. Our earliest fruits started to develop blossom end rot and after applying this the first time it improved the fruit going forward and we haven’t had an issue since
