My watermelon is starting to produce! Last year I got 4 from the plant but I watered it too much so they weren't sweet at all. Any advice? The steps I've taken so far are: Moved the watermelon plant from the bottom of the hill to the top, where the rain won't settle. Haven't watered it myself, but have left crabgrass around it to hold moisture and absorb excess rainwater. The crabgrass is getting tall, so I'm considering trimming it down, or possibly pulling it entirely. What do you think?
