KNOTT’S BERRY PLACE y y Trees and Vines 
which is just when the leaf buds (not 
blossom buds) are commencing- to open. 
If you have been very seriously both¬ 
ered the past season by your berries not 
ripening, give them a second spraying, 
consisting of one-quarter pound of solu¬ 
ble sulphur to five gallons of water 
when in full blossom. 
For white scale (rose scale) near the 
base of the canes, use one-half pint of 
good oil spray, Solite, Yolck, or several 
others, to 3 gallons of water. Apply this 
in the winter while the vines are dor¬ 
mant. 
If strawberries should be attacked by 
aphis (small green plant lice), dust well 
with Nico Dust. If strawberries are at¬ 
tacked by red spider (an exceedingly 
small red or yellow mite on the under 
side of leaves) spray thoroughly with 
one of the light oil sprays. We have 
found nothing as good as solite for this. 
The hard part and the important part is 
to get force enough to whip the leaves 
around so that the spray thoroughly 
covers the underside of all of the leaves. 
Sometimes one or two spoons full of 
sulphur scattered close around the plants 
on a hot day will create fumes enough 
to kill the spiders. 
If any other conditions should arise 
which require spraying, we would sug¬ 
gest that you write for the bulletins 
listed below on this page and also take 
the matter up with your local horticul¬ 
tural commissioner. If at any time we 
can be of any help we will be glad to 
do so. 
Brief Instructions for Growing 
Asparagus 
Plant in a deep furrow one foot apart, 
making the rows six feet apart. When 
the plants have been set in this deep 
furrow cover only about two inches deep 
and then as they grow work more dirt 
to them until the furrow is finally filled 
up. This is to get the crowns down 
deep so that they will not be injured by 
cutting. No asparagus should be cut the 
first season. In the fall when the tops 
turn yellow cut them off to the ground 
and manure heavily. The next spring the 
bed may be cut for a while, but must 
be allowed to fern (grow tall tops) each 
summer and fall in order that the plants 
may recuperate and be ready for cut¬ 
ting the following spring. 
Helps for Berry Growers 
During the course of a season we re¬ 
ceive a very great many letters asking 
information concerning berry growing, 
and while we are always glad to answer 
these questions as best we can, some¬ 
times it would take many pages to an¬ 
swer completely. It is impossible, in as 
small a book as our little catalog, to 
give very complete directions for plant¬ 
ing, irrigating, pruning, and caring for 
all the different varieties of berries. The 
University of California at Berkeley, 
and also the Department of Agriculture 
at Washington, issue a number of circu¬ 
lars and bulletins on growing the differ¬ 
ent varieties of berries which will be 
mailed to you absolutely free if you will 
ask for them. These give a great deal 
of detailed information which is illus¬ 
trated with pictures, making them very 
interesting reading for berry growers.

Part-Time Worker is Satisfied 
Just about a year ago you shipped 
me an order of berry plants and I 
wish to tell you that nearly every 
one is living and doing fine. I am 
working only part time here and I 
planted these on my place near 
Shandon and every one says I have 
a fine looking patch. The red rasp¬ 
berries have done fine and if they 
produce like I think they will I 
want to plant an acre next spring. 
It seems too hot here for the black 
raspberries, for they have not done 
so well. The blackberries and 
Youngberries have done fine. I have 
over two hundred Youngberries and 
more than three hundred blackber¬ 
ries. The dozen Cherry rhubarb 
plants all lived and are doing very 
well. We have had some berries 
from this field this fall and it sure 
looks like we would have lots of 
berries to pick next summer. 
Yours respectfully, 
GEORGE ROLFE.
