Hi, thanks for the reply. I asked because i have two Honey Mezquite plants grown from seeds bought from the USA. You may call it famine food, however i have found Mezquite powder in a health food shop here in Greece, packed in a little bag next to other "superfoods" (e.g. baobab powder, siberian ginseng powder, ling zhi / reishi mushroom powder and so on), so it is treated as a superfood here! I bought and ate that powder, it is reminiscent of carob, but quite better than carob, easily dissolved in water and i take directly powder into mouth, easily digested and wholesome. I suspect you people in America do not fully realize what treasures your nature has for you.
Anyway, one of the two Mezquite that i have, it has passed two winters and now is growing new leaves with the new springtime. The second one, quite smaller, is not (yet?) growing new leaves, and the main stem looks dry except for the lower part which is still green. So i wonder if it needs water, and i have watered it well, now waiting to see if it revives. I asked whether one tree is self fertile, in that case the second one can dry out and some other little tree can take its place. And because the bigger one has not shown any flowers (now growing leaves after second winter), i asked how old it should be to grow flowers. If i have no answers to these, i shall simply wait to see.
