Can Last Year’s Tomato Plants Produce Again This Year?
I live in Berkeley, where the winters are mild. My two very productive tomato plants from last year are still alive, albeit a bit bedraggled. Would it be a good idea to prune them back a little, to encourage new growth, and try harvesting from them again in 2020? Or should I uproot them and replace with new seedlings?

They can produce quite well, if they have the climate for it! Wait until Spring, when it becomes the vigorous growing season, and prune it then. This will help regenerate the plants. You may also want to apply a layer of compost or topsoil to give them a boost for the year, at that same time.
