bottom tomato rot on plants in pots
I have a tomato plant in a pot and the tomatoes have developed bottom tomato rot. Should I transplant the plant in the ground or leave it in the pot and just fertilize? What is a name of a good fertilizer that has calcium? Thank you.

If you are getting this problem in containers, it is likely not a calcium issue, but rather a water issue. Plants in containers have a hard time taking up enough water, which means they can't take up enough nutrients (like calcium). Increase your watering. These plants should be getting water at least once a day and 2X a day if you are experiencing temps above 85F. This will provide enough water to allow the plants to take up the nutrients they need and should stop the blossom end rot.
