I need to confess what I did to my garden. Week 1: every plot was thriving -- all green (color 3). Week 2 is when I made my first mistake. I was supposed to water the whole garden, but I only watered the bottom two rows (rows 2-3). The top two rows (rows 0-1) wilted to yellow (color 4). I also left my lawnmower parked on the cell at row 2, column 0 -- it crushed that one plant, turning it red (color 2). Everything else in the bottom two rows stayed green. Week 3: I panicked. I overwatered everything. The yellow cells in the top drowned and died -- they turned red. The green cells in the bottom rows all wilted to yellow from overwatering. And that one red cell from the lawnmower? Dead beyond recovery -- it went black (color 0). Week 4: I replanted the whole garden. I managed to restore most of it to green, except the entire top row (row 0) where the soil was too damaged -- those stayed red.
