GREAT CROPS OF STRAWBERRIES AND HOW TO GROW THEM

PEARL, ONE OF THE BEST OF THE EXTKE.MELY LATE VAKIETIES 
PEARL is an ideal late variety. Of Indiana origination it has approved itself over a very larjre territory. It is one of the 
latest of extremely late varieties and is a tremendous yielder of very beautiful fruit. The berries ripen evenly over the en- 
tire surface. In flavor it is mild and sweet; in form the fruit is round and large. Pearl is an exceedingly vigorous grower 
with heavy root system and foliage entirely fi-ee from rust. It stands a drouth as well as does the Senator Duniap. George T. 
Baird of Kansas wrote us under date of June 28, 1915. as follows: "Regarding Pearl. I wish to say that it is the finest late 
berry grown in this part of the country. We had our last mess of Pearl June 25th when all other berries had been off the 
market two weeks. Pearl is a perfect mate for Kellogg's Prize. They make a great team." Grown at our Three Rivers farm. 
ties in all cases where our customers desire such 
information and if the varieties you order will not 
mate perfectly, we shall so advise you. Let us 
say here that the proper mating of plants is one 
of the most important elements in successful 
strawberry production. 
Cultivating the Plants 
(CULTIVATION should begin immediately after 
^ the plants are set and should be repeated 
every week or ten days throughout the entire 
growing season. In cases where the field is some- 
what extensive we recommend without hesita- 
tion the Planet Jr. 12-tooth cultivator, which we 
can supply you at factory prices. These culti- 
vators reduce the soil to a perfectly fine state and 
thus insure large yields of perfect fruit. In han- 
dling the cultivator go very close to the rows, but 
see to it that no soil is thrown upon the crowns 
of the plants. If any soil is thrown upon the 
crowns, be careful to see that it is properly re- 
moved. After each rain, just as soon as your soil 
will permit, cultivate the plants. Never culti- 
vate the soil after a rain, however, until the soil 
will crumble in the hand. To cultivate while the 
soil is still "pasty" simply would result in the 
baking of the soil and the consequent injury to 
the plants. In cases where the soil tends to bake 
a five- tooth Planet Jr. cultivator should be run in 
the center of the spaces between the rows. This 
tool may be used with entire safety to a depth of 
from four to five inches, as the shovels do not 
come close enough to the plants to affect the roots. 
The importance and influence of cultivation 
may not be overestimated. Cultivation aerates 
the soil, which is essential to bacterial life; it 
forms a dust mulch which retains moisture dur- 
ing dry times. Moisture that works up from the 
lower soil to the surface by capillary action is 
held in reserve for the plants when they need it 
most. Cultivation destroys weed seed while ger- 
minating and controls all obnoxious growth. 
Cultivation changes the position of the soil and 
aids decomposition and nitrification of vegetable 
matter. Cultivation discourages the multipli- 
cation of insects. And it insures the grower 
against loss by drouth and weeds and saves much 
hand work. To sum up the advantages of re- 
peated cultivation, let us say that it creates and 
establishes a dust mulch ; the dust mulch prevents 
the escape of moisture; moisture dissolves plant 
food and aids bacteria in converting such food in- 
to available form for the plants; plant food com- 
bined with moisture makes active roots; and ac- 
tive roots supply an abundance of nourishment to 
the stems, leaves and body of plants. These 
combined with the essential elements furnished 
by the atmosphere keep up a perfect circulation 
and produce a strong vegetative growth. Such 
vegetative growth makes a perfect-working 
plant-machine for the manufacture of a big crop 
of big red berries. 
By all means continue cultivation until late in 
the fall. After you are through cultivating in 
the fall attach a shovel to the rear end of the 
Planet Jr. cultivator (the shovel should be about 
three or four inches in width) and make a furrow 
in the center of the space between the rows, 
which will act as a winter drain. The water 
from rains and melting snows will, during the 
winter months, drain into this furrow and pre- 
vent the making of ice around the crowns of the
