WISCONSIN AQUATIC NURSERIES, 
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 one 
acre.

Water Cress 
The Water Cress is used largely by breeders of 
Wild Ducks, who consider it very valuable as a food 
plant for their Duck Farms. It grows very rapidly. 
WHEN, WHERE AND HOW TO PLANT 
Water Cress may be started either by planting 
seed or transplanting plants from April to July. It 
grows in cool waters, usually where there is a slight 
current, like in springs, brooks, small streams or 
shallow ponds. In transplanting plants simply set 
them out by hand in shallow waters 1 foot or less 
in depth. Seed is best planted by mixing it with 
mud and dropping bits of the mixture here and 
there in the waters. Three pounds of seed for one 
acre. 
Water Cress Seed $7.50 per pound.
