Currently growing some fruit seedlings/plant at home. It resembles more collecting than anything else. The plants are contained in a rectangular 7x22 in. plastic plant pot. Mainly citrus (over 20 species, all grown from seed in a month! Avg hgt 7 inches) and passion fruit. If anyone is interested/inclined, can send them to you for a small cost in March and forward.
Had been inspired by a youtube vid "how to make compost" user: kitchengardeners. Combining mixed ratios of carbon-source and nitrogen-source materials -- e.g., like home-grown clippings of grass with twigs and dried leaves and this ebay seller, his store site on ebay: Polynesian Produce Stand . It goes to show you how diverse our vegetation is (in this case, with respect to fruits).
On the same note, there are many sellers on ebay that sell relatively cheap seeds for various fruits, herbs, and vegetables -- highly recommend you buy from ebay than home depot or lowes (sorry advance to anyone...). For $10, you can buy seeds of tomatoes (beefsteak, cherry, roma, etc), chinese/american parsley, italian/greek oregano, cilantro, cucumber, radish, lettuce, beansprout, peppers ....endless options and varieties.
I personally think this can be the NICHE for small black enterprise. Always a fun and learning activity for children, very worthwhile in my opinion.
