How to Sow
Watermelons are best sown directly where they are to grow, but you can start them pots, especially if you want to get an early start. Cover your seeds lightly with soil, and keep moist until they germinate.
How to Harvest
Check whether your melons are ripe using one or more of the following tips. If you have a good ear for pitch, knock on the flesh and listen for the distinctive hollow thump sound. Look under your melon. The part resting on the ground should be yellowing. Look for the nearest tendril, it should be starting to turn brown. Once you’re satisfied that it’s ripe, cut it off at the stem with a sharp knife or pair of secateurs.
