Watermelon Growing Guide
Crop Rotation Group
Cucurbits (Squash family) ●
Rich soil with plenty of compost added. Often grown in widely spaced enriched hills, or in well-aged compost heaps that include some soil.
After plants set fruit, feed twice, at two week intervals, with a water soluble plant food.
Single Plants: 90cm (2' 11") each way (minimum)
Rows: 90cm (2' 11") with 90cm (2' 11") row gap (minimum)
Sow and Plant
Sow seeds 1 inch deep in rows, or in hills spaced 6 feet apart. After 2 weeks, thin to 2 plants per hill. If your growing season is short they can be started indoors in pots to get a head start.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Fruit size varies with variety. Small watermelons mature quickly and take up less space compared to huge watermelons.
Ripe watermelons sound deep and resonant when tapped, and the curled tendril opposite the melon should be brown. Wipe clean and store indoors.
Control weeds early and then mulch to avoid trampling the vines after fruits have set.
