Suggestions for Growing Boysen Berries. 
The best time to set out the plants is 
January, February and March in Cali¬ 
fornia, and as early in the spring as the 
land can be worked in the colder sec¬ 
tions. Most seasons February is the ideal 
time in California. Set the plants six 
feet apart in the rows; if the ground is 
very rich they can be set seven or eight 
feet apart and still make all of the vine 
you can use on the' trellis. Space the 
rows six feet apart. This is a very ex¬ 
ceptional berry, for even though it pro¬ 
duces an enormous crop still the berries 
are very large, and by very large we 
mean BIG; bigger, we are sure, than 
anything you have grown or seen before. 
But in order.to get both very large ber¬ 
ries and a big crop there must be some¬ 
thing put in the ground to produce them, 
so keep them well watered and well fer¬ 
tilized and be surprised and happy with 
the results. 
After your plants have started to grow 
well, if manure is available, it will be a 
great help if you will scatter 10 or 15 
pounds of chicken manure or 20 or 25 
pounds of barnyard manure per plant 
down the irrigation furrows and work it 
into the ground. If manure is not easily 
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.
