One interesting thing to try with the vine is as it grows longer, slowly overtime clip off small branches (you can clone them) and bury the stalk/trunk/main stem of the tomato plant. It will grow roots, meaning the entire plant has a larger root system so it will keep growing larger and longer, so more nutrients shoot through it. Don't do it on all of them or if you only have one. It takes a while and it stunts growth and fruit growth. They do that it hydroponic green houses.
So, you would not stake the plant up & just let it crawl along the ground? Does it produce any fruit or does all it's energy go into spreading? I planted a ton of seeds so if they are successful I am going to try it. I'll take pictures to share.
Do you know if strawberries behave the same way? I planted three plant last year and all they did was spread which is good for this year cause I have a bed full of plants but they didn't flower! Thinking they were focusing on spreading instead of producing I cut some of the vines... so far the plants have gotten bigger more lush And, I think I have buds!?! I hope I didn't screw up!
