Growing notes
Watermelons are warm-season crops that require consistent and abundant moisture but will not tolerate wet conditions. They are more cold-sensitive than cantaloupe and require truly warm soil to thrive.
Harvest signs
underside or 'belly' of the melon turns from a greenish white to buttery yellow or cream, fruit tends to lose its slick appearance on top and becomes dull when ripe, browning of the pig's tail (light green, curly tendril attached to the vine near the melon)

Common questions
How much water does watermelon need?
Watermelon has middle-of-the-road water needs. Aim to keep soil moisture around 40–65%, letting the top inch dry slightly between waterings rather than staying soggy.
Can I grow watermelon in a raised bed or container?
Watermelon vines and sprawls, so it needs a trellis or plenty of ground room. Only compact varieties really suit containers.
Does watermelon come back every year?
No — watermelon is an annual. It completes its life in one season, so you replant it each year.
