Pumpkins have become the Christmas trees of fall festivals,
the Easter bunnies of Halloween. From jack-o'-lanterns to the formal
centerpiece, pumpkins are a focal point of autumn.
But if you want the perfect pumpkin come October, start planning now. Oh, sure,
you could just drive to your local retailer next fall. But that would take the
challenge out of it.
To grow your own Great Pumpkin, first choose the variety you want, so you can go
ahead and order your seed.
Pumpkins come in all sizes, ranging from a few ounces to well over 100 pounds.
The world record tops 1,000 pounds. They also come in three basic vine types:
bush, semibush (or semivine) and vining. If your space is limited, you may want
a bush or semibush type. However, most of these types don't grow really large
pumpkins.
If you want the blue ribbon at the county fair or a pumpkin you can carve a
small playhouse out of, you'll probably want to grow a "Prizewinner"
or "Dill's Atlantic Giant." If you're looking for a large
jack-o'-lantern type, try "Harvest Jack," "Pro Gold 500,"
"Jumpin' Jack" or "Autumn King." Good semivine types in this
size are "Appalachian," "Magic Lantern" and
"Aspen."
Some of the smaller jack-o'-lantern types also come on semibush vines.
"Wizard" is an excellent choice. Vining types in this size are
"Gold Fever," "Gold Standard" and "Pro Gold 300."
If you want something different, try "Lumina," a white pumpkin. For
the little guys, "Munchkin," "Jack-be-Little," "Li'l
October" and "Li'l Goblin" fill the bill.
Now find a site that's well-drained and gets plenty of sunlight. The best place
is nearby and close to water, with plenty of room. If you want to incorporate
soil amendments such as manure or composted leaves, work them into the soil when
you till it. Turn the soil first, then till it deep. Incorporate about 1 pound
of 10-10-10 per 100 square feet during your final tilling and form a
well-tilled, smooth seedbed. The soil pH should be between 6.2 and 6.6.
Incorporate lime a few weeks before planting to adjust soil pH. If you start
with low-pH soil, you'll be disappointed.
The plant spacing will depend on your vine type. As a rule of thumb, plant rows
of pumpkins 8 to 12 feet apart. With vining types, plant the hills about 4 feet
apart. Space hills at 32 inches for semivine types and 2 feet for bush types.
Plant so your harvest will begin by mid-October. Southern-grown pumpkins don't
store well, so planting them early is no real advantage.
Pumpkin varieties will be ready for harvest in 85 to 120 days. Decide when you
want to harvest and count backward to find the planting time. You may want to
plant a few days earlier than that, just to be safe.
Once they're in the ground, managing pumpkins is critical. Keep the area
well-watered, but not really wet. After about three weeks, apply another pound
of 10-10-10 per 100 square feet by scattering around the plants (not right on
them). Apply another pound just before the vines start to run.
Watch for pests and diseases, and apply appropriate insecticides or fungicides
if they show up. But don't hurt the bees. Pumpkins need them for pollination.
Keeping the vines dry helps. Water only when the vines have time to dry before
dark. Unfortunately, a couple of evils can strike that we can't do a lot about
in the garden. Viruses that affect pumpkins and a condition called silver leaf
are hard to control, especially in south Georgia.
If one of these hits you, there's always the local produce stand.
