I don't know how long I need. I do know I am slow. I get tired, I get very stiff and I have to get up and rest. But then I just go on. When I say planting for weeks, not everyday. Sometimes it rains. And I just can't plant all day from early morning till night. Too tired after a few hours. But the planting has gone on for weeks here so I have been planting for weeks. Not done yet either.
