which are very profitable. In the Rogue River Valley of Oregon is found several very fine 
orchards grown both under irrigation and without. California plantings up to the present 
time are rather limited to certain sections along the coast north of San Francisco and 
in the mountainous section near Nevada City but filberts will thrive in many sections of 
California and bear heavy, profitable crops. 
Filberts respond to cultivation and thrive best where water tables are low and 
should not be planted on sour, heavy soil. 
Certified Yields 
A. G. Holman of Albany, Oregon, reports a yield of over 2 lbs. average on a block 
of 1200 Barcelona trees 4 years old (accurate weight totalled 2717 lbs.). The same block 
averaged 5 lbs. their 5th year. R. W. Grant of Vancouver, Wash., reports a yield of 
i,y 2 lbs. average on 120 DuChilly trees their fifth summer and 2*4 lbs. average their fourth 
summer. A local grower of Brixnut filberts secured a yield of 22 lbs. on 8 year trees. 
Individual yields on 6 year trees at Eugene show as much as 15 lbs. but from our rec¬ 
ords would state that the following yields may be expected where proper nursery stock 
is planted where soil condition is of average fertility: Six year old—300 to 600 lbs. per 
acre or 100 trees; (8 year old—750 to 1200 lbs. per acre; 10 year old—1000 to 1500 lbs. 
per acre; 15 year old—2500 to 3000 lbs. per acre); 20 year old—from 3000 to 4000 lbs. per 
acie Production 
Filberts often set on trees planted the first and second year, proving them to be 
very eager producers. Before entering into this subject we wish to state that soil fer¬ 
tility, cultivation and pruning will govern production to a large extent. Six year trees 
often produce 5 to 8 pounds of nuts. 
Seven year trees in our own grove have 
produced 22 lbs., but averaged around 
14 pounds to the tree per acre. Yields 
reported from various growers in the 
Willamette valley show that 9 to 11 year 
trees vary from 15 to 35 pounds per 
tree. The scion wood for our grafted 
filbert stock is taken from trees with 
a record of 45 to 60 pounds in their 
12th year. Mature trees have borne 
more than 100 pounds in Oregon. At 
prices far below the average now re¬ 
ceived per pound by Oregon filbert grow¬ 
ers, we consider that they would still 
be a safe and profitable investment. 
More than 4300 pounds were taken from 
an acre and a quarter at Linneman 
Junction, near Portland. Cost of pro¬ 
duction is very low compared with many 
horticultural crops. No expensive ma¬ 
chinery, sprayers, driers, trays, or lad¬ 
ders are needed in the production of 
filberts. Rain nor frost have any effect 
on this winter blooming crop. They 
have withstood very severe weather at 
blooming time and bore heavy crops. 
Filberts fall to the ground early in the 
fall and are picked up and stored in 
boxes, where good air circulation can 
take place. We suggest that trees be 
kept in tree form, as this will be a great 
aid in cultivation. 
Propagation 
We offer three distinct types of Nur¬ 
sery grown Filbert Trees. Each meth¬ 
od carries certain distinct advantages 
adaptable to certain soil conditions in 
various sections along the Coast. We 
will gladly aid you in selecting the right 
root stock for your locality.
