extreme tomatoe vines
 

We have a "EARLY GIRL" tomatoe plant. we just picked off 90 tomatoes
because the vines got so long and heavy, that they bent the cage. They
went over the top,which is 4 feet high, then grew down to the ground
and are now growing out all over the garden. They usually keep growing
untill the end of October.
Are we supposed to prune them in some way as they are growing? The
vines are over 10 feet now. HELP. San Rafael, Ca.
