Planting & Growing

Mielhart Watermelon will grow to be about 24 inches tall at maturity, with a spread of 6 feet. When planted in rows, individual plants should be spaced approximately 3 feet apart. Because of its vigorous growth habit, it may require staking or supplemental support. This vegetable plant is an annual, which means that it will grow for one season in your garden and then die after producing a crop.

This plant is typically grown in a designated vegetable garden. It should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. This is a selected variety of a species not originally from North America.
