It said on the seed packet "does not need support" but don't believe it! Well, they'd probably grow fine without something to climb on, but I noticed last year any moisture on the ground overnight struck the leaves with mildew, when it gets humid here. Or some other disease that speckles all the leaves suddenly. So I like to keep them lift up, clear of the soil. After weeding the bed today, found a bunch of sticks and tied up each plant with some strips of rag.
Here's the row from one side
and from the other.
