Things You'll Need
Instructions
Travel south of Rustboro City to Route 104. Enter the Pretty Petal Flower Shop, which is east of the bridge on this route. Speak to the owner of the flower shop and she will give you the Wailmer Pail.
Walk up to any patch of dark brown soil. Press "A" to pick any of the berries growing in the patch. Go to the Berry section of your Bag by pressing "Start." Use the D-pad to highlight the name of a berry and press "A." Select the first option. Your character will plant the berry in the patch.
Press "Start" and go to the Key Items section of your Bag. Highlight the "Wailmer Pail" with the D-pad of your Game Boy Advance or Ninendo DS. Choose "Register" to equip the item. When you press "Select," you will use the item without going to your Bag.
Press "Select" to water the patch of soil. Get an alarm and set it for one to two hours. When the alarm rings, return to the patch of soil and press "Select" to water it. The more you water the patch of soil, the more berries you will harvest.
