I have 5 plants in a 4'x4' square. I grow some up a fence, some grow into the potatoes.

If you grow them up a fence supply some kind of hammock. If they're the kind that slip from the vine when ripe and you don't give the melon support you will know they're ripe when they're laying on the ground with a big crack.
If they're not slip types you don't need the support.
But since these are market melons I assume you don't know, better safe than sorry.

I should put two plants per raised bed then - the drawers are not that big..
I feel bad for the rest of the seeds.don't want to throw them away..i might give them to friends along with the info that I have collected about carring for them.
I got greedy and planted all seeds from one melon and now I have lots of little plants growing :)
I am not sure what kind of melon is, but I grew up eating them(in Romania)... They are very sweet and juicy have a great smell to them.It was almost the size of a football, but they also grow smaller than that too.The skin is yellow and lots of ridges(looks like a mesh) on it..but not as many as a american cantaloupe has , and the shape is oval.
I took few pics of the piece I have left(flesh and skin) , but can't figuere how to post pictures here.
Anyway..thank you for your help!
