Cherry Tomato Help, Please!
Container gardening for the first time this year...boy, have I learned a lot, but need your help on the tomatoes. The cherry tomatoes are growing in a large 25-30 gallon pot. I planted 3 plants in that pot, which I now know were 1-2 too many. Anyway, I started them in a Miracle Grow potting mix (I know, need one of Al's mixes, but was too late for this year by the time I read about them). I picked 8 of them last night that seemed red enough to pick. On the bottom of ALL of them are one large brown circle about the size of a dime. Not a hole like a bug or worm, just an ugly perfectly round brown circle about the size of a dime. So this morning I checked my still green tomatoes and they have them too. Yikes! Does anyone know what is going on here?
