Rhubarb
:An Old Fashioned Garden Treat
by: Liz Roberts
Growing rhubarb is like having your own piece of Americana. A
century ago most homeowners planted this perennial , harvesting
the stems for delicious pies and compotes. It is not widely used
as other vegetables are, but this dessert staple is rich in potassium
and Vitamin C. Rhubarb requires more care than the average backyard
plant yet any intermediate gardener can have great success with
it. Extra nurturing will produce an abundant harvest.
Rhubarb’s history goes back farther than just 19th and
early 20th Century America. It is actually a staple of Chinese
healers. Ancient Chinese farmers cultivated rhubarb as early as
2700 BCE and it still is used today as it was then in treating
fevers and constipation. It is a colorful plant with hugely extravagant
leaves topping pink or red stalks. The stalks are the only edible
part of the rhubarb. The leaves are extremely toxic and if eaten
can cause serious lung, skin or kidney damage. Still, rhubarb is
a great addition to your garden and diet. It is mostly made into
pies and serves as a foil to other fruits, offsetting their sweetness
with its’ tart flavor.
There are many different kinds of rhubarb. The most popular is
the Crimson (also known as the Crimson Wine or Crimson Cherry).
Its’ stalk, both inside and out, are a deep vibrant red.
You can also grow rhubarb indoors with such types as the Victoria
and German Wine. Their stalk color varies, depending on where they
have been grown. Planted inside a shedor basement, their petioles(leafstalks)
will turn out to be green with a slight speckling that fades near
the stalk’s top. Grown outside, both the Victoria and German
Win will produce almost blood red colored stalks. Other kinds are
the Cherry Red, the Ruby and the MacDonald.
Rhubarbs thrive best in colder weather so the ideal planting time
is late fall. You can also plant them in early Spring if your area
is prone to severe winters. Rhubarb can tolerate most types of
soil. They grow best in fertile, well drained areas that have a
make up of high organic matter. A clean planting site is necessary.
Do not plant where you have previously sprayed herbicides since
none are considered “rhubarb safe.” The plant is also
tolerant of soil acidity but does best in a moderately acidic dirt.
You can grow it in a pH of 5.0 however it will grow better in anywhere
from 6.0 to 6.8. (along with guaranteeing a more abundant harvest
later on). You will also need liberal quantities of fertilizer.
Crop quality large depends on the care and fertilization given.
Each plant should be appropriated one cup of 10-10-10 fertilizer
each spring. Spread it around the base in a wide circle. Also before
planting, work plenty of either well rotted manure or compost into
the dirt.
When planting , plant only the roots with crown buds. You can
plant the seeds yet these take too long for the plants to become
established. Plant the roots with the buds two inches below the
soil’s surface. Space roots 36 to 48 inches apart. Try to
plant on raised beds to avoid the crowns from rotting. Rhubarbs
love a good drenched soil, so water them frequently. If you have
rhubarb from previous growing seasons you can dig them up and divide
them into six or eight pieces for new roots. Each piece must have
one strong bud to survive. Always dig the roots of your healthiest
rhubarb the spring before to establish a new bed. Discard any older,
imperfect roots.
Cultivate shallowly as often as necessary to remove weeds. Apply
a complete garden fertilizer before any growth appears in the spring
and then apply a high nitrogen kind in late June. Also apply this
in late fall or early winter. Do not cover the crowns!
Rhubarb’s growing season runs from April to September although
it can be forced grown even in the dead of winter. Forcing involves
digging up its’ roots and replanting them in large, preferably
wooden pots. Leave them outside after three or four hard freezes
then bring indoors to a dark, temperate place like your basement.
Then keep them covered with either peat, soil or sawdust. After
harvesting,, plant them back outdoors again and protect them with
a good coating of mulch.
Refrain from harvesting your rhubarb during their first year.
Each stalk needs to build up its’ food reserves in its’ roots
to produce thick, robust stalks. This will not happen if you cut
them down too quickly. Stalks may be harvested for one to two weeks
during their second year and eight to ten weeks (basically an entire
harvesting season) during their third and subsequent years. Harvest
in the fall only when the plants are to be discarded during the
next season. To harvest, pull the stalks from the plant and trim
the leaf blades or leaves. Remember the leaves are TOXIC! Your
stalks should be crisp, dark red and fairly thick. Yield and quality
are the highest when the leafstalks have reached their full size.
Also harvest them before any coarseness appears. You can store
your rhubarb stalks in your fridge unwashed and tightly wrapped
in plastic for three weeks.
Rhubarb is an old fashioned treat no gardener should miss out
on. It may require a little more care than the average vegetable
but the end result is worth the concern and pampering. Treat it
with tenderness and you’ll have a delicious harvest of ruby
red stalks – perfect for your pies and compotes!
