Watermelons spacing

At my new garden I have a plot 18X10 designated for watermelons. I never grew them at a such big lot, I always had 3-4 ’ wide beds where I planted 2 on 12’ long bed or 4 on 20’ long bed. How many watermelons I can plant on 18X10 plot? South side of it actually is open to the lawn, so I can allow them to spread out of the plot that direction. What would be the best planting scheme? (I want to plant regular watermelons, not a bush type. )

Follow the instructions on the seed pack. plant 2 long rows 1 foot from the grass edge and you can plant other crop between the 2 watermelon rows. Make sure you plant compatible plants for good results. spacing depend on variety

Mine spread out about 10 ft in every direction. Yours may be smaller but still I’d say no more than 10 plants.


I thought 9 - every 2 feet in one row placed about 3 feet from the grass edge. But not sure if 6 is more realistic.

The package direction usually do not apply to my scenario, this is why I am asking.

I would plant 9 and if all of them grow normal consider removing 3 leaving 6 to grow and produce. I grow much more vigorous watermelons than some indicate here. Mine normally send runners out 30 feet and sometimes more.


I usually plant more compact ones, but it is great idea to start with more and remove later.
