The Moringa is just a little tough to germinate. Plant a lot of seeds. After that, it grows like a weed. Two other inside producing plants are papayas (very easy from seed) and what are called "
condo mangoes". I've seen inside citrus, but the best is something with a soft skin like a tangerine, tangelo, or satsuma. Myer lemons produce fairly well as indoor outdoor potted trees. I suggest 10 gallon containers for indoor trees if you want them to produce.
re the Moringa. Interesting. I had never heard of it till the oranges tragically disappearing here in SWFL. Greening is destroying all the groves, and soon there will be no more Florida oranges. My neighbor just tore out half of his Valencias and disced up the field. He’s going to try growing Moringas.
