I have planted 2 watermelons in early summer & they produced 3 good sized fruits, 2 are still on the vine & now the vine is sending out lots of runners with numerous fruits which I have pollinated, it's now early Autumn. Will these fruits mature or does the vine die off once the cooler weather starts?

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.

I have 1m square veg boxes. In one I've only planted a few pumpkin seedlings. Can i use the rest of the space to grow watermelon? Will they be compatible?
