I had never thought about growing watermelons vertically but after reading about it in Mel Bartholomew's Square Foot Gardening I thought I could give it a try. Due to size considerations I planted sugar baby watermelons and so far I have several growing up the trellis already. The largest is soft ball sized and there are a few grape sized melons as well. I will have to rig up a sling from cloth to support the watermelons as they grow larger. I've heard a pair of old nylons works well for this purpose. Sugar babies grow to about 12 lbs. so I'm curious if I'll be able to keep them on the vine until they are full grown. This should prove to be an interesting experiment indeed.
