Hi! This is my first time gardening so I am unsure of how to space my tomato plants along a trellis. I will have 15 feet of trellises based on this video, one 10-foot and one 5-foot. I've read that you can reduce the spacing between each plant if you're using a trellis, but I'm not sure by how much.
I have many Sun Gold plants, two Roma, one Super Sweet 100, one Mr. Stripey, and one Defiant. Ideally, I would like to plant 2 Sun Gold, 2 Romas, 1 Super Sweet, 1 Mr. Stripey and 1 Defiant. I'm open to planting some in containers, planting some with a tomato cage or, as a last resort, making another 5-foot trellis. I definitely want to plant the indeterminates on the trellis.
Anyone have any ideas on how to space them, or which ones I should plant in a tomato cage or in a container if I don't have enough room? Also, does anyone have recommendations on stringing the trellis: should I make a net or just vertical strings (or different styles for different tomato types)?
