Commercial Culture 
Select a fertile acid soil, such as you’d 
find in a drained Blueberry (Huckle- 
berry) marsh. It must have ample 
water. Wild Blueberries (Huckleber- 
ries), white cedar, leatherleaf, red 
maple all indicate a suitable soil. Low 
meadow lands are often suitable. Set 
plants 5 x 8 ft. (about 1000 per A.).

KEITH'S Acid Peat.

acidity and contains the necessary

vated Blueberry. In it they will grow 
and produce their big, beautiful ber- 
ries. We recommend it for this 
purpose. It should be mixed 2 to 1

more acid and the more humus in 
your soil the less Keith’s Acid Peat 
Humus necessary. 
It is also very beneficial in build- 
ing a lawn, enriching your garden 
soil, and the soil around shrubs, 
roses, etc., and the growing of straw- 
berries. It’s a soil builder and makes 
plants grow. PRICE: 2-bu. bag $1.00;

Greatest Development in Years 
This new development, added to the present list of fruits, 
give fruit-lovers a new rare treat, and afford growers an 
opportunity to realize some of the largest returns yet 
from their soil. It takes only 1000 Cultivated Blueberry 
plants to set an acre and the returns from that acre will run from 
$2700 to $8600. This is what takes place-—a single Cultivated Blue- 
berry Bush will produce from 18 to 24 pint boxes of berries which 
bring the acre yield from 18,000 to 36,000 pints per acre, and they 
wholesale for at least 15c per pint or $2700 to $3600 per acre. A Blue- 
berry Planting, whether large or small, will bring in more and quicker 
money than a fruit orchard. 
Planting Lasts a LIFETIME 
One planting of the Cultivated Blueberries in your garden or field 
lasts a lifetime, and they begin to bear when the plants are four years 
old, sometimes three. This is why we recommend our 3 or 4. year 
(fruiting size) plants. You will get berries so much sooner, and more 
sure of good growth than when the 2-year size is planted. 
WILL GROW ANYWHERE—Garden, Lawn, Field 
Keith’s Cultivated Blueberries will grow anywhere—a few bushes at 
one end of your garden—as a lawn bush (hedge or otherwise )—or in 
your field, will surprise you with their BIG, BEAUTIFUL BLUE ber- 
ries, five times larger than wild ones found in swamps, berries large 
as grapes, with a delicious Blueberry flavor, and lots of them. Note 
the clusters on the 5-year-old bush shown below. 
EASILY GROWN—How To Grow Them 
Garden Culture 
Garden Culture: The only thing out of the ordinary in growing Keith’s 
Cultivated Blueberry is the soil preparation. They will grow anywhere, 
and your soil can be made suitable with little effort. All you have to 
do is to see that the soil is moist, loose, and acid. To accomplish this 
we suggest the following. Dig a hole 16 in. square, 12 in. deep and fill 
with a mixture of one-third your soil and two-thirds acid peat, leaf- 
mold, marsh soil, or better yet use our Acid Peat Humus in which we 
guarantee our Cultivated Blueberries to grow. (See Offer on this 
page.) Pack the soil mixture firmly in the hole and set the bush in the 
middle. Water thoroughly. Don’t let the soil become dry at any time.
