Do you have fire ants, because fire ants down here loves mulch to build their nests under.My preferred method of growing cantaloupe and cucumber. A 16’ cattle panel bent and anchored in an arch. If you put plenty of hay etc underneath the ripe cantaloupe drop to the ground without damage or you can do as I and make little ‘Bras’ out of garden netting. Solves the problem of insects destroying the fruit on the ground as well as not easily finding them in the weeds/vines
