Perhaps
you have been encouraged by your kids, grandkids or just
the kid in you to try your hand at raising holiday
pumpkins - either for Halloween or Thanksgiving - in
your garden but were afraid to try. Don't despair.
Growing those holiday pumpkins is much easier than you
may think. The two primary requirements are appropriate
timing and a lot of space.
When to Plant
The most important thing about growing the great pumpkin
is timing since your goal is to have your crop mature at
the proper time. Most pumpkin varieties need about 90 to
120 days to reach maturity. So, that means that you need
to plant sometime between June 1 and July 1 in order for
your pumpkins to mature by Halloween (October 31).
Pumpkins keep well after they have been harvested, but
there is no way to rush the ripening process if you
plant too late. We started our pumpkin patch last year
on July 1 and had tons of pumpkins of all different
sizes for both Halloween and Thanksgiving.
Space Requirements Next to timing, the amount of
space required to grow pumpkins is an important
consideration. A hill with a couple of pumpkin plants
will require up to 200 square feet of space (that's the
amount of space in a 10 foot by 20 foot garden). Last
year we planted ours where the sweet corn had grown and
it worked out perfectly with the pumpkin vines filling
the space where the corn had been. It was an attractive
addition and helped hold the weeds at bay as well. If
space allows, you could follow just about any crop or
group of crops that have already been harvested by mid
June with a crop of pumpkins. Although we have never
tried it, it is conceivable that you could plant your
pumpkin seed in a small area of your garden and just let
the vines take over the rest of your garden as summer
progresses and the other crops finish their cycle
without removing the spent plants.
Varieties
There are several types of pumpkins that you can plant.
The really large types like Dill's Atlantic Giant and
Big Max are fun to grow since they can reach bragging
size without much trouble. There are also smaller types,
some of which are horticulturally classified as squash
although they look just like pumpkins. The way to tell a
real pumpkin from an impersonator is to study the stem
at harvest. The stem of a true pumpkin will be angular
and tough when you cut it. The stem of the look alike
will be round and much easier to cut. Otherwise, they
look and taste the same. Some pumpkins come in different
shades of orange as well as blue and white. Jack Be
Little is a midget variety that produces pumpkins small
enough to fit in the palm of your hand. Lumina is a
white pumpkin that can be down right spooky when painted
up as a jack-o'-lantern. Mammoth Gold averages 20 to 25
pounds and is a good choice for pies.
Soil
Preparation Pumpkins will develop Texas size root
systems so they need to be planted in relatively loose,
well-drained soil. They will respond well to the
addition of several inches of high quality compost over
the entire planting area. At this time you should also
apply several pounds of barnyard manure or organic
fertilizer per 100 square feet to the planting bed. If
you garden in East Texas check the pH prior to planting.
Pumpkins will not grow well if the pH is below 5.5 so
the addition of lime may be necessary. If possible,
incorporate these amendments into the planting bed with
a rototiller. This will also reduce weed competition,
loosen the soil and get your pumpkins off to a healthy
start.
How to Plant Plant your pumpkins
in hills or groups of about 5 to 6 seeds, 1 to 1-1/2
inches deep. With summer planting it is helpful to apply
a thin layer of compost to the freshly planted seed bed.
This will help cool the soil and retain moisture. Soil
temperature should be between 75 and 95 degrees at the
planting depth. Space the hills about 6 feet apart in
rows that are at least 8 feet apart. In actuality, most
gardeners may only plant one or two hills because of
limited space. If that is your situation, consider
planting your seed around the perimeter of your garden
to conserve space. The growing vines can be easily
redirected before the tendrils become attached to your
favorite rose bush or your wife's Lexus.
Depending on the weather, your seeds should germinate in
5 to 7 days. Once they have emerged, wait about 10 days
and thin the plants to the two most vigorous seedlings
per hill. Use scissors or your fingers to snip off the
seedlings to be removed to avoid damaging the roots of
the remaining plants.
Water Requirements
Pumpkins are fairly drought tolerant but need a good,
deep watering once a week if rainfall does not occur. If
you fail to keep them well watered they may drop their
blooms and not form any fruit. Even if you water
adequately, you may notice that the leaves will wilt in
mid-afternoon on a midsummer day. But don't worry. This
is a common occurrence and the vines will bounce back as
evening approaches.
Fertilization If
your plants show a lack of vigor or you just want to
maximize production, top dress your pumpkin vines with
compost tea or a couple tablespoons of nitrogen
fertilizer about three to four weeks after you have
thinned them.
Pollination
Pumpkins,
like other cucurbits, require insects, namely bees, for
pollination. That is why it is best not to use any toxic
insecticides on your vines, particularly in the early
mornings when bees are present. Just remember: No bees,
no pollination. That is, unless you do the pollination
yourself which is very doable. In the early morning,
just take a little pollen from the male flower (flower
will be attached to a plain stem) with a Q-tip and apply
it to the pistil inside the female flower (one with
small pumpkin at its base). The female flowers are only
open early in the morning and only for one day so timing
is important here as well. Within a few days of
successful pollination, either by bee or by thee, you
will notice the small pumpkin behind the petal of the
female starting to swell.
Insects/Diseases
There are several insects and diseases that affect
pumpkins. Most problems, like squash bugs, aphids and
cucumber beetles, as well as powdery mildew and downy
mildew are manageable using organic techniques. The
biggest problem we have had in the past was with powdery
mildew which thrives in hot, dry weather which is so
typical of our Texas summers. Pumpkins are so tough that
we have found it very easy to grow a good crop without
spraying anything other than a little water/citrus
oil/compost tea to chase the cucumber beetles off into
the next county. Of course, we scout for squash bug
casings and remove them when found and otherwise use
good cultural practices. Many commercial growers spray
routinely for mildew and insects but we would rather
have our grandkids hugging, carving and eating, pumpkins
free from any residue even if we have to accept a few
blemishes along the way. After all, we want our pumpkins
to glow in the dark, not our kids.
Harvest
Pumpkins can be harvested at any stage. In Mexico, folks
actually harvest the small immature pumpkins and prepare
them just as you would prepare zucchini or yellow summer
squash. Chances are, you will want to wait until yours
are bragging size, or at least mature for the smaller
varieties. When mature, the skin of a pumpkin will be
tough and hard to penetrate with your fingernail. To
harvest, cut the stem with a knife, leaving several
inches on the pumpkin. Use immediately or leave in the
garden for a few days to "cure" if they are intended for
long term storage. Pumpkins will stay good for a long
time but need to be covered or brought inside when a
hard freeze is expected. Pumpkins that are harvested in
September will easily last through Thanksgiving if
properly cured and protected from a hard freeze.
