STORAGE and SHIPPING 
A MATTER of considerable concern to the 
Manning Seed Company has been the determination of the best method of storing 
and shipping seed. As a result of early experiments made by the U.S. Forest Service 
and other agencies, it has been learned that properly handled tree seeds can be stored 
for long periods of time. In 1950 the Company entered into a formal research program 
with the Boyce Thompson Institute for Plant Research to determine the survival of 
certain tree seeds under various methods of storage and shipping. By using the 
information obtained from these many experiments the Manning Seed Company has 
developed storage and shipping procedures that assure our customers of receiving 
seed of the highest quality.
