Okay I feel really really really really stupid but um... how do I water the plant in the middle of my others? My turnips just sprouted and now i can't walk to the middle plant to water it...... I know I'm stupid, but what am I doing wrong?
You're not stupid. You just need to upgrade your watering can to 2 red wonderfuls and 1 blue one or vice versa. I can never remember the right combination unless I'm trying the combination. Good luck.
As long as you have at least one Red Wonderful in your watering can, you'll be able to reach the middle crop. But, to get the 3x3 pattern that shygamrgrrl was directing you toward, yeah, you'll need 2 Reds and a Blue (2 Reds to expand the range forward by 2, and 1 Blue to expand the range to the sides by 2).
