Cutting back tomato plants
In coastal San Diego CA where minimum temperatures this winter were in the mid 40's F, I left several grafted tomato plants in the garden. These plants are now very leggy but are still setting fruit. I would like to cut them back so I could re-stake/cage them. If I cut off the current growth, will the plants re-sprout on the old canes or start new canes?

Yes, as long as the plant is an indeterminate variety, I think it will continue growing after being cut back and produce fruit. I am not sure whether they would grow from new canes or old canes, and I don't know the details of perennial tomato pruning, but maybe you could contact a local extension agent for advice.
