SherryRN touched on a good point about gardening. Spacing. I have it down to a specific method at this point, myself. When placing planting boxes, I leave at least one full space on at least 3 sides so the Sim doing the gardening can reach every plant in it, as you can fit up to 4. I don't waste planter boxes on trees or Sixam Mosquito Traps since they need to be placed in the center and require an entire box each. Instead, I just plant those things straight in the ground. I leave at least 2 spaces between trees so the branches don't overlap, allowing clear visibility of the entire plant.
On another side note, I don't know what they did to the plants since Seasons got going, but the yield has been pathetic. It used to be that most plants put out 10 fruit or flowers a day, but now it's down to maybe 3 if I'm lucky. And with most plants going dormant 1/2 - 3/4 of the year and spending a few days regrowing when they come back into season, it cuts yield even farther overall. I'm really disappointed about this. It's making it hard to build up food and flower supplies. It's very frustrating. Unless it's a coding oversight they intend to fix, it just feels like they sabotaged gardening.
