Answer: I think you may be planting at the wrong time of year. Most vegetable plants won't flower when daytime temperatures are above 90F There are two growing seasons in the Valley of the Sun: February and September. Things planted in February will have time to ripen by the first of May and things planted in late August or early September will have time to ripen by Christmas.
