Begin by planting pea shooters at the point where the roof's angle ends. Note: This is the one to the left from where the roof is flat. At the other side of the roof, plant Wall-Nuts. Leave one empty spot in front of a Wall-Nut. Take Cherry Bombs and Jalapenos with you for random trouble.
 Repeatedly use Melon-Pults with the frost upgrade and few Cattails. Also have two lanes of Sunflowers with the Double Sunflower upgrade, and at the end two Spikes with the Stone upgrade. Place Tallnuts behind the spikes. The Spikes are very helpful against Gargantuars. They will stop and hammer down the rock spikes while hit them with Frost Melons. With upgraded Gargantuars you will probably require Cherries , Jalapenos or Doom-Shrooms.
 Go just soutest of Yantra, which is the town near a lake northeast of Novigrad. This location has eight cows. Use Igni to kill them, then meditate to respawn them. Repeat the process as many times as needed.
 PC  Slightly northeast of Draken Hollow Outpost or south of Garin estate, are fourteen cows in a field. Kill them, meditate, then repeat the process as many times as needed.
 Play the first day in Adventure mode where it is night, or the first day at Survival Night (the easy one). At the start of level, plant Sunflowers on lanes where zombies are not approaching. Ignore the ones they are advancing in and leave the killing to the lawnmowers. When you get enough sun, defend the lanes with Sunflowers. You should be facing only normal zombies. One Peashooter with a Wall-Nut in front should suffice. The hardest part is at the beginning, where you need to gather the sun. Luck will be required because the zombies will spawn randomly.
 Gargantuars will first appear in level 5-8 in Adventure mode. The only other enemies there will be regular and Cone Zombies. Set up two columns of sunflowers, two columns of kernel-pults, then two cabbage-pults. Convert as many of the kernels into Corn Cob missile launchers as desired. At least two are recommended, however the rows with the launchers will require extra defenses to prevent the zombies from breaking through. Once the Gargantuar appears, fire both missiles at it. You do not have to kill the Mite.
 Try to complete this later in the Bowling Wall-Nuts mini-game. Unlock the second bowling mini-game and attempt it there.
 Potato mines are obtained after level 1-5, "Wall-nut Bowling". Plant one in the front of your first zombie at the end of the row in level 1-6.
 Play Zombiquarium and do not purchase the trophy for 1,000 Sun. Continue until you have 8,000.
 Growing the Tree of Wisdom for 100 feet requires 94 bags of Tree Food and $245,000. To make this easier, Play the Survival: Endless and Last Stand; use money from Zen Garden; kill Zombie Yeti; and play the mini games Wall-nut Bowling 2 and I, Zombie.
