Just wanted to add - from the age of about 6 my parents would take me berry-picking, so that's cheap labour if you needed it. My dad used to drive tractors from age 12ish (might have been 14-15, think he's told me 12 with supervision, but was driving at 14-15 on his own) for his uncle on his farm, so it is do-able with children growing up.

Good luck with it, whatever you pick!
Actually some states have cracked down on children working on farms, too many accidents and deaths I think. So it pays to look up what is legally allowed when it comes to children working.

Wattle - hope you make the right decision, it is all very exciting to have such choices.
