Large and sweet, six new cherries are ready to grow on the prairies.
Yes, cherries, some the size of quarters, will thrive here in zone
two! After 50-years of
breeding work, the University of Saskatchewan is delighted to introduce
their Romance Series: Romeo and Juliette, Cupid and Valentine, Crimson
Passion and Carmine Jewel.
Saskatchewan cherries are
tart cherries, also known as pie cherries.
Commercial pie filling uses tart cherries, Prunus
cerasus. The fresh
cherries we buy in the store are Prunus avium, or sweet cherries. Technically, the Saskatchewan cherries are sweeter than
Prunus avium, but contain more citric acid, resulting in a bold mix of
sweet and tart.
Dr. Bob Bors, plant breeder,
at the U of S, intentionally selected dark fleshed cherries for health
reasons. Generally, it is
accepted, the more colorful the fruit, the greater the anti-oxidant
properties. Processors of conventional canned cherry pie filling add
colorants to make their product red.
The Saskatchewan cherries are naturally bright red.
Cherries contain melatonin,
says researchers from the University of Texas.
They also found tart cherries contain anti-oxidants, having
ten-times the anti-inflammatory properties of aspirin!
Tart cherries help relieve
arthritis pain, gout and even headaches, says scientists from Michigan
State University. A gentleman
reported after drinking tart cherry juice for one-week that his arthritis
pain dramatically disappeared. You
might say, tart is smart! The
American Cherry Marketing Institute, www.cherrymkt.org is a great site to
discover more health benefits of cherries.
The Romance series is
bigger, better, redder and sweeter than the commercial tart cherries grown
in Michigan. These prairie
cherries weigh between four and six grams and have a brilliant red color
throughout the whole cherry. The
brix rating, can be as high as 22 which makes them as sweet as many grape
varieties.
"Which one should I
plant?"“Plant all six,” says Arden Delidais, owner of DNA
Gardens, who runs a tissue culture lab and specialty nursery on a farm
east of Red Deer. The tissue
culture lab enables DNA Gardens to work closely with plant breeders to
introduce new varieties such as these cherries.
By planting all six
cherries, the harvest will be extended from
the end of July to mid September. “Anything
that expands our short growing season is a great thing!” says Delidais.
Each variety has about a three-week harvest period and will over
lap the ripening of the next variety.
Yields of two to three ice-cream buckets per plant are possible.
People tend to pick the fruit too early when they first see bright
red coloration. The Romance
Series gets sweeter and mellower while it waits to be picked, unlike some
fruits that dry up or fall off the plant when ripe.
If space is an issue and
fresh eating is your main objective, you should plant Juliette, Crimson
Passion and Cupid. Cupid has
the largest fruit and is the last to bloom and fruit.
It has a firm texture similar to a sweet cherry.
Crimson Passion is one of the smaller shrubs producing very sweet
fruit, sometimes the size of a quarter!
“Juliette’s nickname was Sweetie, if that tells you
something,” says Delidais.
When planting, choose your
sunniest site, at least four to five hours of full sun a day. Tart cherries can be planted in hedge-rows four to five feet
apart. They require thorough
watering during the first three years of establishment.
“It is always good to
mimic nature,” reminds Delidais. Mother
Nature is typically hot and dry in late summer and this helps plants
terminate active growth and set buds in preparation for winter.
By reducing water in August and September, you encourage the
establishment of winter buds and increase hardiness. “You can kill anything with your water hose if you water
too long into the fall.” After
letting the cherries dry down, you should wet the soil thoroughly just
prior to freeze up, some time in October.
In about four-years, once
the cherries are old enough to produce fruit, you will need to change your
watering practice. Watering
fruiting cherry plants in the late summer helps to size the fruit.
Pollination can be an issue
with some fruits but these cherries are self-fertile, meaning if you plant
one cherry, you will get fruit. Yield
is enhanced when more than one variety is planted. Bees work well and gently brushing the blooms will also
stimulate greater fruit set, says Delidais.
These cherries are well
behaved and do not sucker much. Plant
breeding used Mongolian cherry for hardiness, but this also brought
suckering. “Years of
selection work deleted the nasty suckering habit and left the
hardiness,” explains Delidais.
For locations where it is
hard to grow plants, Delidais recommends Carmine Jewel. This cherry was the first to be released in 1999 and it
ripens earliest in the season.
Delidais refers to Carmine Jewel as “a little princess,”
because it is a petite plant, growing only six-feet tall, with a neat,
tidy habit of growth, glossy green leaves and crisp white blooms.
“Carmine Jewel has the nicest ornamental characteristics.”
The first Carmine Jewel
cherry plants sold, are now bearing fruit and ecstatic customers are
returning to buy more. Cam
McLeod of Shackleton, Saskatchewan can't plant Sk Carmine Jewel fast
enough. He says, "I
can't say enough good about them! They
are fantastic little plants. You
might say I am plum pleased!" Delidais,
who has 30- years of experience
growing saskatoons finds them
very consistent and hardy. Carmine
Jewels are doing well in Fort Macleod, another tough growing climate.
“Carmine Jewel are shaping up to be the workhorse of the
burgeoning cherry industry,” predicts Delidais.
These prairie hardy cherries
are easier to grow than many other fruit trees.
They are good candidates for organic production and
home-owners because most insects and diseases do not bother them.

Large acreages of cherries
are being planted commercially in Alberta, Saskatchewan and Manitoba.
Saskatchewan cherries are natural dwarfs, growing only six to eight
feet tall making them easy to pick. Our
American neighbors are also excited to learn of these dwarf cherries, as
the ones they grow are 18 to 25 feet tall.
DNA Gardens has seen interest from producers in New York,
Minnesota, Idaho, Tennessee, Alaska and North Dakota.
DNA Gardens is one of the
original five propagators with a license to grow these plants. Propagation is by license and royalty fees from each plant
are collected on behalf of the University of Saskatchewan.
Growers are so pleased with the plant material and the extension
work the university conducts, most feel the royalty fee is a good
investment.
These prairie hardy cherries
are great fresh, in pies, juiced, sauces, stuffing, and fruit-shakes.
For an absolute burst of flavor, dry them, and add them anywhere
you would use raisins. Kids
love them as sour candies, and moms can be assured these are a healthy
snack. |
