Let them grow they probably will produce fruit but probably not as good as the first 3. Yes the plants will die back some time.

I have tomatoes growing with a watermelon vine. The watermelon is doing well, but the tomatoes’ leaves are growing distorted. Does anyone know about interplanting these two crops? Should I pull the tomatoes out?

Tomato yellow leaf curl virus went through southern Qld back in 2009 or so. It has probably spread far wider by now. The leaf is like your hand with the fingers still curled in. The leaf doesn't open out and grow. The plant becomes stunted. Caused by the silver winged fly. Look it up on the internet. It can be stopped with a soap spray. If no success pull it out and put in rubbish bin. It wiped out the tomato growing industry in Bundaberg.

Has anyone growen watermelons in Wellington?

I'm growing them for the first time, in Manawatu. So far with the heat and sun we've been having they're doing well. But they'll need a long season, so fingers crossed. My first transplant died in the wind, so shelter is important, in Wellington too :-)
