Duckroot Seed
Duckroot Seed grows 
Duckroot when planted on a 
Farming Patch.
Don't try to eat this.
Obtaining
Buy this seed from 
Platy’s Smuggler’s Shop for 
10 after completing 5 Mallard Smuggler Tasks. Seeds can also be given as rewards, and harvesting Duckroot can return seeds of the same variety.
Planting
Move the seed from your bag into a 
Seed Box. Build a 
Gardener’s Shed nearby so ducks can collect their 
Tools. A duck prepares a Farming Patch with a 
Rake, takes one seed from the box and plants it. If you want this variety to grow, stock the box with only this seed type.
Growing and harvesting
Ducks use a 
Watering Can to help the crop grow faster, then harvest it with 
Gloves. The harvest adds Duckroot to your bag for 
Cooking. It can also return seeds; better Gloves increase that chance. Refill the Seed Box and prepare the patch again to grow another crop.
