PICKING BOYSENBERBIES 
One of our greatest problems last summer was keeping- our pickers satisfied. 
They all wanted to pick Boysenberries and we couldn’t blame them. 
available about one pound per plant of 
fishmeal, bloodmeal, tankage, or mixed 
fertilizer scattered in the irrigation fur¬ 
rows after the plants have started to 
grow, will make them grow big, strong 
vines the first year. You should strive 
to get a heavy vine the first summer in 
order to support a maximum crop the 
next season. 
Then in the winter while the plants 
are dormant they should be fertilized 
again, this time is for the fruit. An 
application as suggested above is enough 
on good rich land; if the soil is run 
down or not rich another application 
about the time the canes start budding 
out in the spring will pay. They should 
be kept well watered all season and the 
whole space between the rows should 
be kept quite moist. They should be kept 
especially well irrigated during the pick¬ 
ing season, once a week is about right 
on most soils. 
We prefer to let the vines grow on 
the ground the first summer and we put 
them up on the trellis just as the leaf 
buds start opening in the spring. The 
trellis can be put up any time during the 
winter at your convenience. As the canes 
grow this first season they should be 
pushed back in line with the rows so 
that you can irrigate and work between 
the rows. If it is inconvenient to let the 
vines grow on the ground, the trellis 
can be built early in the spring and the 
vines can be wound on it as they get 
long enough. The vines should not be 
trellised in bunches, but should be 
spread out over as much surface as pos¬ 
sible on the trellis. 
In the spring of the second growing 
season, and shortly before the berries 
start getting ripe, there will be heavy 
new canes come from the crown of the 
plants. To make picking easy these 
should be cut out just before the berries 
start getting ripe. When the crop is all 
picked, the old canes that have borne 
fruit should be cut off the trellis and 
back to the ground and burned. By that 
time the new canes, which are your fruit 
wood for the next season, will be sev¬ 
eral feet long, and these new canes are 
allowed to grow on the ground until the 
following spring and are then put up 
on the trellis at the end of the dormant 
season as before. 
Each season shortly after the canes 
are trellised up, and just as the leaf buds 
start opening (usually early March), the 
vines should be sprayed with lime-sul¬ 
phur solution mixed at the rate of one 
part lime-sulphur to ten parts of water.

Be liberal with your Boysen berries 
and they will do a lot for you.

Gentlemen: 
Undoubtedly you will recall having had some corre¬ 
spondence with us concerning your new Boysenberry. 
and you may remember that I bought 75 plants from 
you February 10, and another lot March 10, after I 
saw that the first lot were doing so well. Every plant 
lived and is growing fine. At this time, with much of 
the growing season still ahead, these plants have from 
10 to 40 canes each, and some of the canes are 15 
feet long. I have never seen berries grow like these 
do. 
If these will produce fruit in Florida, like the 
Boysenberries I saw at your place last summer, they 
will be a money making addition to our fruit line. 
From the way they are growing I can see no reason 
why they should not produce just as well here as they 
do in California. 
Sincerely yours, 
(Signed) M. E. Clark.

pleased with the growth they have made in spite of the dry weather.
