Regrowth (also known as Refresher) is a Boost that revives all wilted crops and zombies on the farm. After being revived, your crops and zombies will become ripe again, meaning you will have another chance to harvest them before they wilt again. It can be bought in the Market or earned from the Zombie Salesman, but cannot be won from an Invasion.
In Zombie Farm 2 this boost was renamed to Refresher due to the wilting mechanic being removed. When used it now makes all old crops fresh so they can sell for maximum gold.
