Hi Bill and Goldie.
On funding your hobby, some people make some money selling plants, etc., but for most of us this hobby funds itself in a different way:
1) You really can save a lot of money growing your own produce (which means not having to buy as much at the store);
2) The health benefits of home-grown organic produce are enormous, and you could save thousands, and even hundreds of thousands on medical bills over a lifetime by eating more home-grown organic produce (with all the anti-oxidants, vitamins, minerals, soluable fiber, etc., and none of the pesticides, e-coli, heavy metals, etc.);
3) You get great exercise gardening, further contributing to your health; and
4) You can't buy the joy of seeing your own figs, etc., grow and fruit, a peace and happiness that further contributes to your health and quality of life.
So even if you never make a penny in cash, you are saving big bucks over the years.
And if your spouse doesn't buy any of that (all of which I sincerely believe is absolutely true), ask them to think of all that things you might be getting in trouble with if you weren't busy out in the garden! ;-)
