(Farming Efficiency tips)
Now obviously every now and then you'll be extremely tempted to take the gralats from your farm and go out and spend them. But how much exactly should you spend? First, you should buy a select amount of flowers from a furniture shop. I recommend the cheap ones at Belle Garden. Arrange the flowers on your grass in a checker pattern so that one blotch is covered with flowers, and the other is bare. Work on obtaining gralats on all patches so there is no gralatless patch of flowered grass or regular grass left. Lock all of the gralats then continue farming. Whenever you feel the need to collect money, unlock the gralats on the grass while keeping the ones that are on the flowers locked. This way, you are still spending the money you've earned but by keeping half of it to continue growing. Over time when the grass blotches regrow and you feel the need to start spending again, collect the gralats on the flowers and leave the ones on the grass to grow. By doing this you've earned a formidable amount of money from your farm without wasting it all. Keep the cycle going, get friends involved too! You can also use this same tactic to divide farms up between helpers by assigning each person to a flower color then arranging the flowers over the farm to divide as equally as possible between farmers. Now no one will bicker on who should receive the highest amount because they already have their cut reserved for them.
I'll add any more tips that come to mind. Good luck farmers!
