Unfortunately I didn't realize until after I looked at the watermelon seed packet, that the variety of watermelon
is the type that can reach up to 25 pounds.

Is it possible to plant melons in a plot as small as 6' x 5'? That is only a total of 30 square feet. I would also like to plant some cantaloupes too however you have to give row spacing of 6 ft per row with the watermelons.

Is it too hot to plant cantaloupes now? What type of soil do melons like in general? I hear they like soil that's a little sandy and you have to give them lots of fertilizer cause to my knowledge, any type of melon is what's considered a "heavy feeder".

For melons, how deep should I dig the soil?

Also how far apart would you space the watermelon hills in one row? It doesn't specify this information on the seed packet; it just says to plant 6-8 seeds in a hill that's 12" in diameter, then thin to 2-3 plants per hill. Doesn't specify how far apart to space each hill in one row; essentially doesn't give the plant spacing per hill.
