Strategies
With
When you have this in your hand and your hero is at low health, it is recommended to place this plant down so you can survive some more turns to get better cards. It is a good idea to shield this plant, as that means your hero and this plant would be invincible for a turn. Boosting this plant is also an excellent decision to use. Guarding the plant with Wall-Nut in its lane can also help it survive longer. It is recommended to try and block the other lanes with plants so Soul Patch doesn't get destroyed.
Against
When your opponent uses this plant, try to bounce it away so you can defeat the plant hero faster or destroy it with instant kill tricks such as Locust Swarm, Cut Down to Size or Rocket Science. Additionally, zombies with the Deadly trait can sweep this plant up as long as the zombie does more than 1 damage. A Knight of the Living Dead could also be a good choice, because it can block its attack and destroy it quickly. An especially sneaky strategy is to use Anti-Hero zombies, such as Walrus Rider or Stealthy Imp, to deal more damage to it, as the damage bonus activates when attacking the hero directly, so the damage input will be far more severe. Try not to Bounce Soul Patch if it is heavily damaged unless you can finish off the plant hero that turn, as Soul Patch can be played again with full health.

Trivia
Its description references Template:PvZHLink and Sour Grapes.
Its appearance and description seem to refer to the hippie culture commonly associated with the mid-1960s.
If Soul Patch is on the player's side, its attack animation is quicker than usual.
In the current update, the zombie no longer attacks again in the direction of the Soul Patch. This fixed a glitch where the game wouldn't respond after using the Bungee Plumber on the hero.
Soul Patch has the highest base health stat of any plant or zombie.
There are glitches where if a Soul Patch is supposed to take an attack, sometimes an insta-block occurs, even though it has been removed. Instant blocks still occur even after it has been destroyed.
It's unknown what the exact cause is, but it's possible Soul Patch's code was updated in the update that added Insta-Blocks to account for those. However, even after the update removing them, Soul Patch still retains the elements of Insta-Blocks, and thusly, can allow this glitch to occur.
There is a glitch where Soul Patchs cannot take damage for the heroes and it has 9 health instead of 10.
Guardian class. It costs 7
