What is the best way to start growing your own tea leaves (buy/plant seeds, other)?

Interested initially for personal use, but also interested in knowing if this is worth pursuing as a business, land/space requirements, any other commercial needs. Any experienced insight (for either personal or commercial pursuit) would be appreciated. Thank you in advance for any help you can provide.

A certain type of Camilla bush is used for tea. I am sure one would need at least an area of 7 * 7 ft. They are slow growing. Do you have the right conditions for it--morning sun, afternoon shade? Also, you can use bay leaves or lemon grass for tea as well.

The "Tea" shrub, (as in "all the tea in China") is Camellia sinensis. Camellias have a limited range they will grow in, Tea can be grown in USDA hardiness zones 6-9. The colder the zone, the slower it's going to grow. Harvesting foliage from the plant will also slow down their growth rate.

Tea is a sort of general term, many many plants can be made into some sort of tea. I'd consider something else... if you want to make 'large' quantities... lemon grass was suggested, chamomile could also work... if you have a large bit of property, Tea could be an option.

I'm not an expert at 'teas', but I hope that this info. helps.
