HOW TO GROW GARLIC
Once you have
obtained your organic planting stock from www.TheGarlicStore.com or one
of the reputable suppliers who are sprouting up around the country in
response to garlic mania, the next question is: how do you grow it?
It's not that hard, but there are some key things to remember. We are
happy to share our experiences with you, although they may be biased somewhat
by our western climate - cold winters, hot summers and low humidity year
round. The hardneck garlics especially do well in colder climates. In
fact some thrive on being in the ground during very cold winters (upstate
New York is a center for hardneck growers). We will be happy to share
your growing ideas and successes with other visitors to the site. Just
e-mail us with your
comments and we will incorporate them into these pages on a regular basis.
Naturally
if you really want to dig into this topic, you must read Ron Engeland's
classic book "Growing Great Garlic".

But now, let's turn to this year's crop

SOIL
Garlic likes full sun and well drained soil. Garlic is quite tolerant
when it comes to soil types and textures, but it definitely appreciates
sandy-clay-loam that is friable (easily crumbled in the hand) and has
a high organic content. It does best when the pH is in the 6.2 to 6.8
range. You can get your soil tested at the local university extension
office or use one of the soil test kits on the market. Make sure you take
samples from several spots in your garden and mix them together to obtain
a representative reading. The garden or field should drain easily - standing
water just won't cut it as the bulbs could rot in the ground. To increase
the tilth of the soil (isn't that a great word?), add organic matter such
as well-composted manure. You can also green mulch, that is plant cover
crops such as clover or buckwheat and then till them into the ground.

PREPARATION
As with most crops, proper soil preparation is essential. If you
have a large enough field, disc and cultivate to really work up the soil.
If you have a large garden, do the rototiller thing. If you have a small
plot, spade up the top 6 to 12 inches. Garlic roots like to go deep, so
well cultivated soil is a big help. Mix in the organic matter and manure
at this phase. After the deep tilling, we find a final pass with a cultivator
that powders up the upper several inches of the soil aids in planting.

PLANTING
When to plant? The fall is best. Remember garlic is a bulb (like
tulips and daffodils). Plant 4 to 6 weeks before significant ground
freezing may occur. On the High Plains, we like to get going by mid-September,
since snow by the end of September is not at all that rare here. Further
east and south, late September and into October will generally do. The
idea is to get the cloves in the ground during warm weather so germination
occurs and good root formation follows. It is good sign when you get
green shoots popping above the soil in late autumn. Don't worry. The
tips may suffer a little winter burn, but they can tolerate zero and
below. Studies have actually shown that some garlic leaves actually
grow ever so slightly on sunny days with temperature is below freezing.
Recent tests have shown that early spring planting provides good results
not only in the South, but also in colder areas.
When do you "crack" the bulbs? Since one obviously does not
plant the bulb whole, you must crack (split) the wrapper and separate
the individual cloves. It is best not to do this more than about 48
hours before actual planting, or they will begin to dry out and lose
viability. Incidentally, one half pound of garlic typically has about
3-5 bulbs. And each bulb has somewhere around 5-15 cloves (it depends
on variety). Thus at the most you'll have somewhere in the neighborhood
of 15 to 75 potential plants per half pound of garlic. You can get a
return of about seven times for a successful planting. But keep one
rule in mind: bigger cloves mean bigger bulbs. Thus the smaller cloves
should not be used for you main crop.
What can
you do with the small clove culls? Well, you can eat them. Or, here's
a secret: use them for spring baby garlic. Just go ahead and plant them
like any other garlic, in a separate plot and with a much tighter density
(1-2 inches apart is fine). In May when the plants are about 12-16 inches
tall and look like scallions, dig them up. And prepare for a real culinary
treat. They have both the look and texture of scallions, but they taste
of pure garlic. Try them in salads, braised, with roasts, in stir fries,
whatever. They are just great. You can also plant spring cloves for
greens and have a nice crop in 60 to 90 days.
How deep
to plant? We find the tips should be about 2 inches below the soil surface.
For elephant (Buffalo) garlic, make that 3 to 4 inches. Be sure to plant
with the pointy side up/basal plate (root) down. They will grow at other
orientations (they're tough plants) but you will have bent stalks which
detract aesthetically from the final product.

How
to plant? While we use a modified onion planter, most people do it by
hand (as do we in our test plots). There are several techniques. In dry
climates we find it works best to let the upper few inches dry out and
then bring in the cultivator, turning the soil almost to powder. Then
you can literally just stick the cloves in the ground by hand and the
soil covers them up as you remove your fingers. If you have heavier and/or
wetter soil, you can poke a hole in the ground with a broom handle and
just drop the cloves in the hole, covering up the entire batch with a
rake at the end. This works best if you water the soil several hours before
planting so it is moist but not muddy.
How close
do you plant them? Our experience is that closer is better. If you look
at the commercial plantings out in Gilroy, they are amazingly tight.
But the cloves should have enough room to grow into large bulbs (at
least 4 to 6 inches for hardneck and 6-8 inches for elephants). The close planting helps with weed
control once the plants get larger in spring as the leaves block out
the sun to the later sprouting weeds. In any case, if you plant in rows,
be sure to leave enough room (24-30 inches) in between so you can get
in there to weed next spring (which you can count on).

FERTILIZING
Garlic appreciates fertilizer, and a good 10-10-10 works well,
typically 3 pounds per hundred square feet. Our practice has been to
till in quite a bit of very aged cow manure during the initial soil
preparation phase. You can side dress the crop when germination starts
in the fall. In the spring, fertilize again, but do not fertilize beyond
late May, since high nitrogen levels at this stage may actually decrease
bulb size. Organic growers such as Yucca Ridge Farm apply foliar sprays
of liquid fish and seaweed fertilizer,
several times in the spring. Some people will dust the bulbs with bone
meal at planting time to spot fertilize and help with germination

MULCHING
This is a key element to real garlic success, and the colder your
winters, the more mulching is essential. Mulch serves many purpose, not
the least of which is to regulate the sharp changes in temperature and
moisture that can occur during winter, especially out west. But it also
goes a long way towards controlling weeds the next spring. Mulch can be
hay or alfalfa (but no seeds unless you want to grow a second crop). Lawn
grass clippings are excellent. Chopped leaves will work if you have them.
At Yucca Ridge we have found that young alfalfa cuttings, grown by our
neighbors John and Cookie (who also supply us Grade-A cow manure) works
very well.

We do have
one problem here, however. It is the wind. Fifty miles an hour is no
big deal on the High Plains. So stuff tends to blow away (into Kansas
in our case). Wetting down your mulch helps compact it, making it less
likely to take off. But we finally resorted to rolling out chicken wire
on top of the mulch. Crude but effective, at least until the wind break
trees grow enough to reduce the problem. You should plan to put the
mulch on immediately after planting (perhaps after giving the ground
a really good watering). Don't be shy on the mulch, at least several
inches should cover your crop. You would be surprised how tough those
shoots are when it comes to punching through the mulch. If you do mulch
extra heavily, removing some of the overburden in spring might be a
good idea, but leave enough for weed control.

IRRIGATION
Garlic is a bit schizo when it comes to water. Most of the time
it really likes moist (not soggy) soil. Watering regularly in the fall
during germination is essential. In dry climates, watering in winter
is also important. Do not let the upper several inches of soil turn
to dust. When do you need to water? Try the old farmer's test of clumping
a bit of soil in your fist. If the clump stays together upon releasing
your fingers, it is wet enough. If not, water. Keep on watering into
the spring when the maximum green shoots are forming. Then about mid-
to late June, or when the scapes (on hardnecks) are standing high, STOP.
During the last four weeks, when the bulbs are finishing off, and the
wrappers are drying out, too much water is not good. You can create
a mold or fungus problem (you don't need that). Wet soil also makes
for dirty and unappealing wrappers. In drier climates some people like
to heavily irrigate at the pre-planting phase to help build a winter
deep soil moisture reserve

WEEDING
Most people hate weeding, but you gotta do it if you want to be
a "garlic pro." (I find it rather therapeutic - I go down to
the field with my headset on and listen to the Rockies on KOA radio while
I mindlessly pull those #$@^*& weeds. Until we find a market for organic weeds, we just yank
them up and use them as additional mulch to further retard new weed growth.
Garlic plants do not like competition, so getting the weeds out makes
a big difference in your results. And don't let them get ahead of you.
Sometime in early May this miracle happens - the little green fuzz of
weeds explodes into a maze of 12 inch high monsters almost overnight.

HARVESTING
Many people make a big mistake at this point. They wait too long
to harvest. Keeping garlic in the ground beyond a certain point does not
result in bigger bulbs, but rather dried out, split and nearly useless
ones. When to harvest? When the lower third to half of the leaves have
turned brown, but there are still mostly green leaves higher on the plant,
it's time to harvest. Others suggest harvesting when the hardneck scapes
are standing straight up but before the pods containing the bulbils open
up. You can always test dig one or two plants. You should be able to see
the shape of the cloves beginning to bulge through the wrapper. On the
High Plains, depending on the weather, harvest can begin as early as the
first week of July. There is also a two to three week difference in the
harvest dates of the several varieties. So watch you plants carefully.
To get the bulb out of the ground, don't just try to pull them. The stalk
will break. You must dig, using a pitchfork or the like in order to loosen
the soil. Then you can lift the entire plant out of the ground.
Don't let
the bulb stay in the sun very long as it will sun scald, which reduces
its quality. For our larger fields here at Yucca Ridge our very clever
neighbor Bob has modified an ancient potato picker which actually does
an excellent job at extracting the plants. (It really helps to move
in next to a guy who likes to weld things and is so clever he makes
you feel quite inferior, which of course you can't admit to him.......
why am I getting into this?)
Incidentally,
many people wonder if the scapes should be cut in order to increase
bulb size? For elephants the answer is definitely yes. For hardnecks,
yes appears to be the correct answer also, although some varieties seem
less affected by leaving the scape attached. Cut them generally just
before the scape has fully extended (or the coils in the Rocamboles
have started uncurling). When still young, the scapes are considered
good eating by some.

CURING
You can pop a bulb out of the ground and take it to the kitchen.
However, if you want to store your garlic, you have to cure it first.
After the curing process they store up to six months. The entire plant,
leaves and all, should be dried out for about two to three weeks. The
drier your climate the faster the curing will go and the less chance
you will have to deal with mold. There are many ways to do it. The simplest
is to tie up a bunch (a dozen?) with string/wire and hang them in a
well ventilated place. Our three sided pole barn is ideal. Do not wash your bulbs or let them be exposed to water. You can also
pack them loosely into large mesh bags or in open sided crates. But
they must get a lot of air circulation. If you do find any that are
molding, throw them away as fast as possible. After the curing is complete,
lop off the tops about an inch above the bulb and trim the roots.
When you
do your sorting, keep your biggest bulbs for planting stock. Remember,
big bulbs come from big cloves which come from big bulbs....and so on.
Also it has been argued that the smaller bulbs taste better (perhaps
by people who have trouble growing large bulbs?).

STORAGE
Storing garlic requires an even temperature (50-70°F seems to work)
and a relative humidity averaging in the 50-60% range. Make sure they
get plenty of air circulation. When storing in bulk, onion-type mesh bags
hanging in a well-ventilated room is good. In a kitchen, a ceramic garlic
keeper (or a burlap bag) will do fine. Do not store at high humidity or
in the refrigerator - they will try to sprout and their taste heads south
in a hurry. As winter approaches you might keep your bulbs in a paper
bag to slow down desiccation. Most hardneck
garlics and elephants can be kept for several months. The softneck
varieties do tend to have a somewhat longer shelf life. |
