I am living in a suburban place in Mexico. When I moved here out of the Puerto Vallarta area, I found someone who had Moringa seeds. I planted 4 and all came up through the winter. Easy peasy. When I tried to transplant the first one, I snapped the trunk. Three left. I started harvesting the leaves, beans, flowers, seeds in the late second year and do so every quarter. All of Moringa is edible and when I air dry the leaves and powder them I have all of the minerals and vitamins , protein, and fiber my body requires and have more to give away. Studies on the nutrition says it supports life on its own and has been used for starving people globally. I keep them at about 10 feet high and they are easy to harvest, hang to dry on a clothes line in my tiny yard, and powder in a couple of days. I gave one to a friend for his birthday and he let his grow. It was 10 feet high when I gave it to hime and now in one year it is 23 feet high and yielding huge amounts of leaves, flowers, beans, and seeds. My current two are in big plastic pots because I am a renter and can move every year or so. As soon as I move to a place with enough space to earth plant them, they will go in. I have 3 4 year old papaya trees grown from seed, ealso in pots, and at least 1 will fruit for me this year. I also maintain 50 lb of dried black beans, 25 lb of rice, and about 25 lb of assorted flours, baking soda, vinegars etc. I will be planting several shallow window boxes with carrots, beets, tomatoes, sweet potatoes, onions, and lettuces in the next new moon. Zucchini is a plentiful yielder, and great picked young. Dried beans can grow and provide plentiful green beans. As soon as I harvest a window box, I replant it with its next crop. Compost all scraps in a trash size bucket for replanting with excellent "gold" soil. Assorted trees well spaced in whatever space you have can provide assorted fruits. I have discovered that once I kicked the sugar habit, I can live very well on what I grow and buy some dairy, eggs, cheeses. Peanut butter is essential. I share with neighbours especially kids.
