2. GARLIC
It is one of the most popular condiment used in
kitchens all over the world. Although some
people avoid garlic because of its intense taste
and aroma, this plant possesses quite a number
of medicinal properties. By cultivating garlic
under cover, gardeners have a quick and easy
access to a natural prebiotic that effectively
counteracts many diseases, strengthens
immunity, inhibits the growth of bacteria and
infection. Just eat one clove of garlic a day to
feel its positive effect after a short time. This
constitutes a sufficient dose of amino acids,
saponins, vitamins, provitamins, mineral salts
and rare elements contained in a small portion
of garlic, replacing many drugs from the
pharmacy. In addition, cultivation of garlic in
foil tunnels allows for planting and harvesting
throughout the year.

3. WINTER OR SPRING GARLIC ?
Garlic is planted in two cycles,
spring and autumn. Garlic winter,
planted in autumn, does not
develop flower shoots. It hibernates
in winter and emerges in spring.
Spring garlic, on the other hand, is
planted in spring.
Winter varieties develop larger
heads and ripen much earlier than
spring varieties. They reach up to
120 cm in height, with bulbs up to
90 g in weight.

4. SOIL AND CLIMATIC
REQUIREMENTS
• SOIL
Garlic is a plant resistant to low
temperatures, growth
occurring at just 3 ° C. For
proper development, it needs
sun exposure, although it can be
planted in the shade. As a one-
year plant, it has a weak root
system. This translates into high
demands on soil and water.
Garlic needs moist, warm and
rich soil in humus and nutrients.
The optimum condition for its
development is a neutral
ground with a pH of about 6.8.

6. Mulching is a treatment that has a positive effect on the yield .
As the edible part of the plant is under ground, the main factor
affecting garlic is the substrate quality. A mulch layer protects
the soil from drying and limits development of weeds. Proper
irrigation is equally important during cultivation, soaked soil
causes the plant to be exposed to disease and pest attacks.

Garlic is a universal plant for intercropping. It is planted to prevent parasitic
diseases caused by fungi. Its intense scent deters a significant proportion of
pests. A good combination will be the planting of garlic in the vicinity of
carrots, cucumbers, tomatoes and lettuce. It is not recommended to combine it
in an area with legumes (beans, peas) and brassica, such as cauliflower and
broccoli. Nothing stops you to cultivate it inside the tunnel, next to bushes and
fruit trees.
You should avoid growing it year after year in
the same spot or after other relatives . Such
action can lead to development of diseases and
pests that appear on the same plant family.
Planting it also close to vegetables that
consume a lot of nutrients leads to low yields.
Good fore crops for garlic would be peas,
beans, and any fabaceae plants.

As we have already mentioned, garlic has high demand on soil and water,
so it is necessary to systematically water and loosen the soil. As with any
plant, it is important to systematically remove weeds and keep a constant
watch on the crop. When pathogens or pests appear, they must first be
identified, to then apply the appropriate remedy depending on the
growing stage.
To increase yield, flower buds should be removed - this will allow garlic to
develop bulb instead of stems.

To store garlic for months, place it in a dark, cool and
ventilated room where humidity is maintained at 70% ,
preferably with a temperature not exceeding 5 ° C. Keeping
garlic this way will prolong its goodness and allows for use
as a seed.

10. When stems on garlic become
brown, then it is time to
harvest. When more than half
of them have reached this state,
it is a sign that they are already
fully mature. Garlic ready to
harvest should have a hard
head or 3 to 5 segments
covered with thin skin. Garlic is
dug during dry and sunny days,
gently removing it, so as not to
damage the head itself. Shaking
it off the ground and hanging it
to dry for at least 3 days is an
effective solution to prolong its
shelf life.
