Nothing, but the garden is covered with compost Fall or Spring.
I try to keep my place very simple but can't seem to resist putting trellises up! Just put up two more last month, not cross braced just 16' cattle panels on t-posts.
It's not like we need the room but I love the look and ease of harvesting
The Orangeglos are all out in the compost pile, the others (1 vine each) are in the 2 okra patches.
