In Plants vs Zombie 2, strategically placing your plants of different functions is at the very core of the gameplay. And it is also the wining-losing factor for most challenges. Given the huge collection of plants and the types of zombies, players need to take a lot of practice to have a better understanding of each type of plant/zombie as well as the playing mode/scenarios. However, there are some general strategies that apply in most situations in this game.

The first plant players would place is the sunflower which generates sun energy for further plant purchases. Therefore, players should plant sunflowers as early as possible and make sure they have enough sun energies. Normally, sunflowers are placed at the back rows of the lawn and for most challenges, players need to have two full rows of sunflowers. Sometimes, players may also plant one row of sunflowers with spaces in between so that they can place other defensive or offensive plants with long shorting range.

Another crucial thing in this game is the right timing of planting. Depending on the specific landscapes(sloops, roof, pool etc.) and the types of zombies, players should consider the recharge rate and attacking range of the plants they are about to plant.

Besides, it is very important to think ahead and plan in advance. Players should always check the incoming zombie or even anticipate them. Knowing what is coming up helps players place plants accordingly at the right timing.

Meanwhile, it should be noted that it is not necessary to always go for expensive plants or power-ups. This game is massively strategy-based and players can find an effective solution for the challenges if they know the functions of the plants and the features of the zombies well enough. Some plants such as the potato mines can be surprisingly useful at a small cost. Plus, when purchasing and selecting plants, players should always consider the recharge time of them and some powerful plants can take very long to be in effect again.
