I have never grown tomatoes in Florida, but one appeared a couple of months ago out of nowhere in my yard. I suspect a bird or other animal passed a seed in its scat.
This vine tomato is growing for a while now, it has grown like a weed and I have had to tie it up to limbs on the lychee it sits under to support its rather heavy weight.
So far 5 tomatoes have set, but I pulled the largest today (about 1.5" to 2" across) as it had a translucent spot about the size of a quarter on one side (it was not touching anything else) and the pulp had turned watery. Is this some indication of a problem with the vine, or is this normal fruit attrition?
