Official gameplay tips
- Plants only grow when they are watered. Rain automatically waters the fields.
- Trees don´t need to be watered.
- You can obtain random seeds and saplings by tilling a field with a hoe. Once you've discovered new plants, they can also appear while tilling.
- In your house, you are protected from thunderstorms. Fully grown plants can be damaged by a thunderstorm if they are not sheltered from the direction the wind is coming from. The best options are to harvest them in time before a storm or to build a greenhouse.
- Growing raspberries early on is essential for securing a steady food supply. They also satisfy thirst a little bit.
