When do I know when my watermelon is ready to pick?
Certified GKH Gardening Expert
If the tendril is green, you should wait to pick the melon. Harvest when the curled tendril closest to the melon on the vine begins to shrivel and dry up. Also, give it a thump and see if it sounds hollow. If not, leave it for another week or so and try again for either the hollow sound or the tendrils dying.
