Farmland Hydration
Water within 4 blocks keeps Farmland hydrated; without water or rain it dries out step by step and then turns into Dirt.
Rules
| Water range | Water up to 4 blocks away horizontally, diagonals included, at the Farmland's own height or 1 block higher. That is a 9 x 9 area with the Farmland in the middle. |
| What counts as water | Still water, flowing water and waterlogged blocks. |
| Rain | Rain falling on the space directly above the Farmland hydrates it like water. |
| Timing | Farmland changes on random ticks: at random moments, on average once every 68.27 seconds per block at the default random tick speed of 3. |
| Moisture | Moisture runs from 0 (dry) to 7 (fully hydrated). With water or rain, a random tick sets it straight to 7. Without them, each random tick lowers it by 1. |
| Turning into Dirt | Farmland at moisture 0 with nothing planted on it turns into Dirt on its next random tick without water or rain. |
| Kept by plants | Dry Farmland stays Farmland while one of these is on it: Wheat Crops, Carrots, Potatoes, Beetroots, Melon Stem, Pumpkin Stem, Attached Melon Stem, Attached Pumpkin Stem, Pitcher Crop, Torchflower Crop, Torchflower. |
| Kept by Fence Gates | A Fence Gate of any kind on top also keeps dry Farmland from turning into Dirt. |
| Solid block on top | Farmland turns into Dirt when a solid block is placed on it. |
