Deep Water 
Duck Potato 
(Sagittaria Rigida) 
Another favorite food for all kinds of Wild 
Ducks. The diving ducks feed on it during fall 
In the deeper waters. Shoal water ducks eat it 
if the waters are low during fall. It is a rapid 
grower and produces abundantly of food. It has 
numerous acorn like tubers on its roots just be¬ 
neath the bottom soils which the Wild Ducks glut 
themselves with. One can hardly drive the ducks 
away from a good bed of Deep Water Duck Pota¬ 
toes and if they do leave it is only temporary, 
they soon return for more. 
Plant the tubers during spring or summer in from 
one to five feet of water. A soft mud bottom is best 
and will produce a luxuriant growth next year. 
They are very hardy and will thrive in any fresh 
water lake, pond or stream. Changing water levels 
do not affect the growth of these Duck Potato plants. 
In planting deep water duck potatoes just fast¬ 
en the tuber to an eight penny nail with a small 
rubber band and drop them in the waters in the 
desired place. One thousand tubers plants on® 
acre.
