How to Store Root Crops
by National Gardening Association Editors
Have your fall garden of root crops mature as late as possible by planting as
late as possible. Cold weather sweetens the roots and you'll be putting the freshest
produce into a cool root cellar, garage or back porch. Leave your last planting
in the ground until the roots are fully mature; they'll store better if they're
protected by a thicker skin.
Whether you're going to eat most of your vegetables fresh, or you intend to
freeze, can, or store them in a root cellar, a good rule of thumb is to harvest
as close to the time you're going to eat or preserve them as possible. This
gives you the best flavor and nutrition.
For a longer storage life, dig up the roots from your fall garden after two or
three days of dry weather. Your root crops will be dry, and by leaving them out
for a few hours in the sun right after you pull them, you'll kill the root hairs,
making the plant dormant, and the soil on the roots will dry and fall off easily.
Never wash roots before you store them. Just cut off the tops right out in the
garden. Leave about an inch of stem for beets, so they don't "bleed" in cooking.
For other root crops, cut the tops close. Wash the roots just before using them.
Only store the best roots. Any that are damaged by insects or harvesting you
can eat fresh. Injuries are avenues of rotting that can spread to the other
vegetables. (Yes, one bad apple can spoil a whole bunch!) If you should bruise
any, eat them right away. Also, don't ever clip off the bottom end of the root
before you put it in storage; this, too, can open the plant to rot.
Storage - Plain or Fancy
Cover vegetables with 1/4-inch layer of insulation.
You don't need an elaborate root cellar to store vegetables, even for months
at a time. You can easily extend the fresh life of root crops using whatever
storage space you currently have. The length of storage time may vary according
to your storage method, but with any of the methods described below, you can
be sure of at least a few extra months of fresh vegetables.
To stay crisp and fresh, root crops just need cool, moist, dark surroundings.
The ideal place would be about 34° F with high humidity. Most gardeners can
only approximate these conditions. But whether you have a root cellar or just
a spot under the back porch for storage, the most important element for long
vegetable life is an even, cold temperature. Variations up or down of even five
degrees can cause new growth to sprout (which you don't want) or rotting. Here,
insulation is the key. There are many ways to give your roots the insulated low
temperature they need.
In-ground storage is the least expensive, most carefree root storage.
If you have an unheated basement, you can build a root cellar by partitioning
off one corner, installing some insulation and a good, sound door. You're actually
making a refrigeration unit.
The temperature inside the root cellar will be coolest near the floor, and that's
the place for your root crops. Don't put them right on the floor -- it may be too
damp. Raising them up on a few boards should do the trick.
If you live in an apartment, you might team up with your neighbors and your
landlord to turn part of the basement into a community root cellar. There are
several excellent books available on constructing root cellars. Two are
Keeping the Harvest,
by Nancy Chioffi and Gretchen Mead (Garden Way Publishing, 1980) and
Root Cellaring,
by Mike and Nancy Bubel (Garden Way Publishing, 1991). In addition, the United States D
epartment of Agriculture publishes a series of free home-building booklets.
If your cellar is cool but not insulated, a large, sturdy cardboard or wooden box
with two to three inches of some insulating material (sawdust is best, and moist
peat moss or sand also works well) on the bottom and sides will do fine. Place a
layer of carrots on top of the sawdust, leaving two to three inches of space near
the sides. Cover the carrots lightly with sawdust--1/4 inch is fine. Alternate layers
of carrots with sawdust, filling in all around the edges with sawdust as well. Add a
final two to three inches of sawdust on top, and store this "root box" in a cool
basement area. In older homes, the cellar steps leading outside make handy storage areas.
Here are some other storage methods that work in a cool cellar. Put the roots
in a plastic trash bag, punch a few small holes in it, tie up the top and store
the bag. Or, put your roots into a trash barrel with a plastic liner, put the lid
on and store the whole thing.
If you have no cellar, you can still use the insulated box method. But you'll
need a really large box (supermarkets usually have some from deliveries of paper
towels and napkins) lined on the bottom, sides and top with four to five inches
of sawdust or peat moss. Pack the roots in the sawdust and store the box in a
cold place--your garage, back porch or an unheated spare room. Whenever you need
some vegetables, just take them out and repack the sawdust around the rest.
Roots can touch each other in storage, just don't pack them in tightly like
canned sardines. Some moist air must be able to circulate.
When you visit your storage area to get vegetables, check for any roots that
may not be keeping well and cull them. Don't worry if a few are starting to
deteriorate--some individual vegetables just don't keep as well as others. The
rest will be all right.
If your vegetables freeze in storage, don't panic. You can still use them.
But once they've thawed they won't keep for more than a day or so.
Your storage method can be as simple or complex as you like, but be realistic
about what your family will eat between gardening seasons. Just as in garden
planning, a small area that you visit regularly is better than a huge one in which
food is wasted.
Of course, if you really want to keep it simple, your refrigerator crisper
drawer will keep roots fresh for several months, but you can only store a limited
amount this way.
