Dot is a luscious mango--juicy and sweet to the extreme with a peachy flavor. One of the best I tasted last summer. I wish you all the luck in growing it. (The Cushman I tasted, on the other hand, was mediocre.)
I lived in South Gate when I was a kid. Not far from Long Beach. Same soil as you have. Man, was it productive in growing the very best-tasting vegetables! We weren't into fruit trees, but we had a Hass avocado and a Babcock peach. In the neighborhood were Fuerte avocados, Hachiya persimmons, Black Mission figs, and apricots. All were outstanding. My relatives in the San Fernando Valley had Santa Rosa and Satsuma plums and nectarines--unbelievably good. Summer was heaven!
