The wonderful news is that my Early Girl Tomato lived up to her name and sprouted blossoms! (in the red circle)
She has easily doubled in size in 2 weeks! Most of the others are growing well too, so I think I will have a good crop in a few months.
The tiny baby blossoms won't become fruit in this awful heat, but it is a very encouraging start.
I am very thoroughly puling weeds and watering every night, but actual fruit is completely up to God.
