Boyseitberry 
Facts 
By IRENE JARVIS 
Owner of 
California Growers Ad¬ 
vocate $1600 Per Acre 
No longer is the culture of the 
Boysenberry an exclusive trade 
of the West. It has been proven 
conclusively that ihe Califor¬ 
nia Boysenberry will grow and 
thrive where any other berry 
will grow. Boysenberry culture 
is a new vocation, very remun¬ 
erative—so much so that many 
growers in every section of the 
United States are choosing Boy- 
senberries for their livelihood. 
A demand has been created 
for canned Boysenberries and 
Boysenberry juice which cannot 
be supplied unless growers in 
the Middle West and East cul¬ 
tivate it commercially. Canners 
and juice manufacturers are 
eagerly waiting for the develop¬ 
ment of the plantations and so¬ 
liciting growers for their crops. 
Why? Because the cost of ship¬ 
ping Boysenberry products 
from the Coast is too expensive. 
A case of pure Boysenberry 
juice received from California 
recently cost $6.50 wholesale 
for 24 pint bottles. Adding 
$ 3.68 transportation charges, 
made the cost per bottle 42c 
“wholesale,” and even at that 
figure there is a scarcity of pure 
Boysenberry juice to be had. 
About 8 V 2 quarts of Boysen¬ 
berries produce one gallon of 
pure Boysenberry juice. 
Figuring 435 plants to an acre 
with an average yield of ten 
quarts to a plant as low a figure 
as 20 c per quart and you would 
have an income far surpassing 
that in any other variety. 
IRRIGATION NOT ESSENTIAL 
FOR SUCCESSFUL CULTURE 
OF CALIFORNIA BOYSEN¬ 
BERRY 
Growers everywhere are in¬ 
quiring if it is necessary to ir¬ 
rigate the Boysenberry for the 
production of berries. 
Irrigation is not necessary 
for the production of Boysen¬ 
berries any more than it is 
necessary for the production of 
strawberries or red raspberries, 
although irrigation naturally 
prolongs the bearing season and 
has a tendency of producing 
more and larger berries espe¬ 
cially if the season is inclined 
to be dry. 
For those who do not have 
irrigation, an application of peat 
about the crown of the plant 
will help to conserve moisture 
although this practice is not 
necessary. 
Under the same climatic con¬ 
ditions the Boysenberry is more 
drough resistant than other ber¬ 
ries. 
THERE IS NO SUBSTITUTE FOR THORNY BOYSENBERRY 
Growers Deceived By Thornless Variety 
Commercial growers, in par¬ 
ticular, are interested in the 
possibilities of the thornless 
variety of the Boysenberry. 
Ever since the introduction of 
the Thornless Boysenberry to 
the West Coast, Boysenberry 
Plantation, Lapeer, Michigan, 
has put forth every effort to 
ascertain true statements re¬ 
garding it. 
Only recently, one of the most 
prominent growers on the Pa¬ 
cific Coast wrote us: “We do 
not grow the Thornless Boy¬ 
senberry nor the Nectarberry. 
We tried them but they have 
never been nearly as fruitful 
as the ordinary Boysenberry. ’ 
He also stated that the Nectar¬ 
berry was so nearly like the 
Boysenberry that there was no 
advantage in introducing it. 
An excerpt from the Califor¬ 
nia Agricultural Extension Ser¬ 
vice says: “Thornless canes have 
been reported on the Boysen¬ 
berry variety by Walter Knott, 
but most thornless mutations of 
such berries are less fruitful.” 
The thorny variety of the 
Boysenberry is not as bother¬ 
some as one is led to believe. 
After the trellising is completed, 
the briars are of little trouble 
as the berries form in clusters 
and stand apart from the canes. 
The chief concern of every 
grower, whether commercial or 
domestic is quality and quanti¬ 
ty. So far, there is no substitute 
for the thorny Boysenberry and 
Ihe GENUINE stock of this va¬ 
riety even yet is not too plenti¬ 
ful. So far, as GENUINE Nor¬ 
thern-Grown stock is concern¬ 
ed, there is a limited supply. 
Do not be mislead by choos¬ 
ing the Thornless Boysenberry, 
which has not been sufficiently 
tried on the Pacific Coast to 
warrant the exorbitant price of 
plants. If this variety had 
shown unusual merits, Boysen¬ 
berry Plantation, Lapeer, Michi¬ 
gan, would have been one of 
the first in the Middle West to 
introduce it. 
The above photograph illustrates the enormous root growth of a PARENT Boysenberry plant. 
The wrapping of a PARENT plant is a very particular job requiring a most painstaking method. 
Root development is the first requirement in successful Boysenberry culture. Our methods pro¬ 
duce results.
