So far, ( as Bobert noted, it is still early in the year for tomatoes here,) trellising the cherry tomatoes ornamentally is working well. I do note that a few of the the lowest leaves on both the Sweet 100's and the orange cherry (I have already lost track of the variety for that one) are showing the first signs of yellowing. The lower one or two leaves of the zucchini are also showing some signs of disease, even before fruit has set. I notice ants are all over both the zucchini and the cukes, but see no signs of aphids.
