Q&A – What causes tomatoes to turn black on the bottom?

Question:
What causes tomatoes to turn black on the bottom?
​​
Answer:
This is called blossom end rot. Alainia Hagerty, owner of tomatobaby.com says this is caused by a lack of calcium in the plant. There may be enough calcium in the soil, but because of inconsistent watering the plant is not able to absorb that calcium. She recommends consistent watering and using mulch to keep the soil from drying out as much.
