Today's harvest: 4 SunGold, 4 Husky Cherry Red(1), 2 Sweet 100 and Sweet Million for a total of 11 tomatoes.
Yesterday I spent a good amount of time clearing out the "underbrush" from the tomato plants. SunGold in particular had a lot of yellowing lower branches. That's natural. There's a ton of tomatoes on the plant and the focus of the plant is pushing out tomatoes at the cost of supporting the lower branches. Kellogg's Breakfast had a lot of yellowing branches but that's because the plant is struggling.
I just kept cutting the lower and yellowing branches on all the plants. They definitely look better now for what that is worth.
Red Boar(2) has a growing tomato on it. This is another struggling plant that's recovered enough to produce fruit.
