I just picked two tomatoes from my garden. They both had a large brown area on the bottom of the tomato. They were not on the ground when I picked them. What causes what appears to be dry rot? Are tomatoes ripening later this year than normal?

It sounds like your tomatoes have blossom end rot. This is caused by a calcium deficiency which is related to uneven soil moisture. Try to keep a consistent level of moisture in your soil to help prevent this. It is best to rotate your tomato planting spots every couple of years also. If it is a problem that reoccurs you may want to consider having a soil test in your veggie garden. Test kits are available at your county extension office or online at the website under smart soils.
