Can I grow Watermellons and Bottle Guards in the same above ground flower bed?

I have a potted back porch garden and am going to build a larger square flower bed to grow some watermellons and gaurds ( bottle variety). I am going to make it about4x4 feet and grow both vines on a trellis. Will the root systems choke eachother?

one problem--water melons don't take too well to growing on a trellis--the weight of the melon will cause it to fall off the vine, unless maybe it s a miniature melon like ice box melon---our melons weigh from 60 to 90 pounds-- here in Mississippi --also melons and gourds are in the same family and might cross pollinate each other, also each takes a lot of room you could only have 1 plant for a 4x4 bed -Gourds are excellent grown on a trellis cause they are hollow and don't weigh much, if you do grow melons on a trellis provide some kind of support under the melon to support it s weight, i have heard of people tying an old nylon stocking round em and tying it to the trellis
Reply:they grow runners so just lead them the way you want them to go either one will only need a couple plants each have one pulled to the right and one to the left
Reply:make sure you get the measurements right and no mistakes ( dont plant the watermelon to close) you will be fine!
