We have been eating tomato's from our three plants (so good):
Then I saw big black balls under the hanging plant:
It took some time to fine why:
Killer tomato worms there were 4 on the plant about 2 to 4 inches long, ugly. They had eaten a bunch of the leaves and half of a green tomato. Funny they don't eat ripe tomato. They ARE NO MORE they went to moth or worm haven.
