Blossom-end rot is the most typical issue we see with tomatoes.
It’s a calcium deficiency that creates that caved in rot on the blossom end of your tomatoes. It can happen when there’s wide fluctuations in watering and/or excessive nitrogen fertilizing.
Mulch your tomatoes with weed-free straw or shredded leaves to maintain moisture levels. Plants in containers need to be watched more carefully as they can’t hold moisture. Add a nitrogen fertilizer a couple of weeks BEFORE you plant.
Leave at least 4 feet of room between your tomato plants. Air flow around your plants will help with humid conditions which can interrupt a plants ability to take up nutrients.
You can use foliar sprays to prevent blossom-end rot but it won’t save tomatoes that already have it.
