There is a lot of work to do, on a very regular basis:
- dig the plot
- clear all the weeds
- dig and clear again. And probably a third time.
- sow your seeds, or plant your plants
- protect them from pests and weather
- water and feed them
- harvesting, which can take you hours if you grow too much!
- there are always miscellaneous jobs to do too, like repairing stuff, building stuff
My plot is cleared, planted and fairly under control, and I still spend 12+ hours a week up there
