Moringa search on a lake shore Paradise

For the past two years we have tried unsuccessfully to grow Moringa trees in Mzuzu. The last time we were in Makuzi Beach we met Aubrey, a bright young man, who agreed to search for a piece of land on which he might sow Moringa as a little business, where we would buy his Moringsa seeds and dried leaves.
Harisen went to see what he had located today.
The altitude in Mzuzu and the fact that it has a cooler climate seem to be a barrier to growth

John,
We went to meet Aubrey in Makuzi today. He phoned on Monday asking me to come and see the land.
I visited the land, but it is too small, walked round it, 263 yards around it.
He showed me another land, closer to the lake, it is a good but best for beach/Lodge/resort.
I took the picture of Aubrey's younger sister at Aubrey's house.
Regards,
Harisen.

Moringa Oleifera (Moringa) is a fast growing, aesthetically pleasing small tree adapted to arid, sandy conditions. The species is characterized by its long, drumstick shaped pods that contain its seeds. Within the first year of growth, moringa has been shown to grow up to 4 meters and can bear fruit within the same first year Virtually every part of the tree is beneficial in some way, which is of great importance in areas where people have a direct dependence on trees, crops and animals for their livelihood.
The juice from the leaves is believed to stabilize blood pressure, the flowers are used to cure inflammations, the pods are used for joint pain, the roots are used to treat rheumatism, and the bark can be chewed as a digestive.
The leaves provide many necessary vitamins and minerals and can be eaten cooked or dried. The foliage has been compared to spinach in both its appearance and nutritional quality. "25 grams daily of Moringa Leaf Powder will give a child" the following recommended daily allowances...Protein 42%, Calcium 125%, Magnesium 61%, Potassium 41%, Iron 71%, Vitamin A 272%, Vitamin C 22%
The seeds can also be used to remove suspended solids from water much like alum.
Is it any wonder we want to grow it?
