Compared to other crops,
Compared to other crops, watermelons aren't usually attacked by bugs. However, if you wish to be safe, a good control is the use floating row covers for the first few weeks; you must remove the covers to allow pollination of the flowers by bees. If you spot aphids under the leaves, spray with insecticidal soap. If you spot cucumber beetles, a spray application of rotenone or sabadilla is advised, but speak to your local garden center first. Avoid watering from overhead; water at the soil line. In terms of rain, make sure your soil drains well and the roots won't stay wet. If the melon splits, pick right away and cut out the split area.
