I was reading that some gardeners are reluctant to grow dwarf tomatoes because the bottom leaves are low, and other leaves are not widely separated, rendering them more susceptible to fungal spores that splash up from the soil during rain. That may only be theoretical, I don't know. So I started adding a brown paper cover for soil under the dwarf tomato plants . Im only doing that if they have real soil, not ones that are growing in artificial potting soil media.
I hope the paper makes a difference.
I have not figured out how to label photos uploaded via ipad. The first tomato plant, in the round container is BrandyFred, and the next two, in the rectangular black container are L to R, Improved Dwarf Champion and Extreme Bush. The last two, in the teal plant box, are Alpatieva 905A.
I've also noticed that most of the dwarf tomatoes have flower buds at their growth apex. I wonder if that is significant?
