Every crop has a sow window. Plant in a good month for a healthy plant and sometimes a bonus yield; plant outside the window and the crop is doomed before it sprouts. Examples reported by players on Build 42: cabbage from February to July, potatoes February to April, corn March to May, garlic July to September, hops and hemp August to October. In-game, the seed packet and the farming panel tell you the right months.
- Growth takes real time: radishes in about a month, most vegetables around two, potatoes and corn around three, and slow crops like tobacco, garlic and hops half a year or more.
- Ground level only by default. Roof farms need a sandbox option switched on.
- Tools: a trowel or shovel to dig, seeds, and a watering can or bucket.
- Grains such as wheat can be harvested with a scythe, which also clears grass for animals.
Plant something slow early. Garlic and tobacco sown in late summer are ready the following spring, when you need them most.
