Going medieval how to grow tall grass?

In Going Medieval, growing tall grass is essential for hay production to feed your animals through winter! Here's what I've learned after many playthroughs:

Tall grass grows naturally on most soil types but you can encourage it by designating growing zones on suitable terrain. It prefers relatively flat ground and will spread slowly over time. You don't need to plant it - it generates naturally.

The key is managing your harvesting: don't clear-cut all grass at once. Leave some patches to spread. Assign a growing zone specifically for tall grass preservation if you want guaranteed hay production.

Hay is crucial for winter animal feed, so harvest in late summer/autumn when yields are highest. Build a storage room to protect hay from rotting. Different biomes have different grass growth rates - valley maps are most productive.

The Going Medieval Wiki has specific mechanics and yield information!

Hey fellow settler! I've sunk hundreds of hours into Going Medieval, and here's my tall grass strategy:

Early game, I immediately designate a large "growing zone" over existing tall grass patches but DISABLE planting. This protects it from being automatically cleared during construction. Tall grass spreads naturally to empty adjacent tiles, so preserving patches is key.

For reliable hay, I maintain several small protected grass patches around my settlement. I only harvest when I need hay immediately or right before winter. Harvesting gives hay AND grass seeds, which you can plant in growing zones, but natural spread is more efficient.

Pro tip: Build a roofed storage area near your animal pens for hay - it prevents deterioration from weather. Also, different animals eat different amounts - horses are hungry!

The valley map type has the most reliable tall grass growth in my experience.
