For the last two years I ended up with leaf blight and because of the small
space I have to put them in the ground I decided to use 18" containers this
year.

To make a long story short my container tomatoes are ending up with cracked
bottoms or they end up being black. I sprayed with daconil this morning but
I am baffled.

I planted them in Miracle Grow potting soil and have them hooked up to a
drip irrigation system that automatically waters them with 1 gal of water
every other day.

All help appreciated. Thanks.
