On-the-Vine Tomato Rooting (Update & Expansion)

This is the rooting I’m trying on my Roma plant. I’m going to give it another week or two before I dig around and check for roots.
I expanded the rooting (enlarging the growth area) that I’m trying to do on my Heirloom Beefsteak. Notice my green onions sprouting up beside?

I also started a brand new rooting today, also on my Heirloom Beefsteak. Wish me luck!
