MG will work fine, I use the MG All Purpose every 2 weeks for all my flowers & veggies. I have many flowers as well as several toms & peppers in pots on the deck.

Some tomatoes split easier than others, but yes having a dry period followed by alot of water will cause the tomato to drink too much and will split the fruit. Cabbages are the same way.

I water mine every day. My pots range from 3-5 gallon size and I have one tomato plant in each, for some of the smaller peppers I have 2 in each. Every morning I drag out my hose and soak every pot. I have some larger pots too (5-8 gallon) those I water every 3 days-again soaking them completly. Consistency is the key.

Your doing fine and josie23 is right about the water thing. If you water consistantly the plant 'learns' what to expect and a rainy day/night won't bother them. Keep the soil slightly damp on a regular basis and fertilize every two weeks. Stop fertilizing when the tomatoes are forming but keep the watering even. You know if you're overwatering when the leaves start to yellow. That means there's no air in the soil: they're drowning. Too much water after a dry spell is sure to make the fruit split. Best of luck.

I had the splitting problem two years ago with several plants. They produced a lot of fruit but if I left them on the vine till they were red and ready to pick, they would split. Even decreasing watering did not help but it may have been too late. So, I picked them early and let them finish ripening inside. That helped.

Then last year and this year I found Large Red Cherry tomato seeds. Those didn't split and I think tasted better. This year I have several of those plants with good fruit and they should be ripe in a few days. Some in the ground and some in 10 gal containers.

I think deweymn has the right idea. I always pick toms early and put on window sill or counter top,this seems to have better tasting ,more production,longer production on my plants. bill w.

Thanks, everyone!! Looks like I am on the right track. I appreciate the advice. Jennie
