It doesn't matter what order you water the Fruit Plant as long as you use three different types of water each round.

Step 2: Mesmerize the Roots

Once all five plants have been grown in your game, head directly under Lab B and use the Skull of Nan Sapwe on the roots blocking a growing spot. Interact with the growing spot to place your bucket on it.

Step 3: Plant and Feed the Plants

Plant three seeds, one in each of the newly spawned growing spots under the lab, and they will transform into Zombie Killer Plants by themselves.

You must continuously feed these plants zombies until a plant grows where you placed your bucket, and interact with the plant to reveal the Golden Bucket that everyone in your game can collect, granting you infinite amounts of every type of water on the map.

You can cycle through each type of water by pressing the Sprint+Melee buttons/keys are the same time on whatever platform you are on.
