Growing Globe Artichokes in Vegetable Garden

Growing globe Artichokes in vegetable garden is an excellent choice for any amateur gardener.

Because by growing globe Artichokes (ie Cynara cardunculus var. scolymus (L.) Fiori) he/she will not only be able to harvest fresh flower heads for many years and for many delicious dishes, but he/she will also have the possibility by leaf extracts of the plant to make effective medicines – medicines to treat liver, digestive and biliary dysfunctions.

And if he/she does not want to make drugs from the leaves, then he/she can give the leaves to the domestic animals he breeds, since they are a wonderful animal feed.

Finally, If he/she does not want neither the fresh flower heads, then there is no reason to go to growing globe Artichokes in his vegetable garden.

Climate and Soil

Climate: Growing globe Artichokes in vegetable garden for many years takes place successfully in those areas of the temperate zone characterized by mild and cool winters and where no sudden temperature changes are observed throughout the year.

The minimum temperature tolerance of the plant is -3 to -5 °C. However, it is advisable not to plant globe Artichokes where the temperature falls below 1 to 0 °C, as no Artichokes should be growing when the vegetable garden to be planted is in a position exposed to frost.

A particularly favorable climatic factor for the successful cultivation of globe Artichoke in the vegetable garden is increased atmospheric humidity.

Soil: The soil of the vegetable garden can be of medium texture or heavy. That is, both clay and loamy soils are suitable for the globe artichoke growing but in any case, they must have excellent drainage as well as be fertile.

Soil pH: Appropriate soil pH for growing globe Artichokes in vegetable garden is between 6 and 8. Optimum ranges between 6 and 6.9.

Globe Artichoke Propagation

Globe Artichoke is propagated mainly asexual, with Pups (offshoots) and Ovoli (dormant or semidormant underground axillary buds). Seed propagation of the plant is rare and is used mainly for the establishment of new varieties.

Sowing: The sowing of the globe Artichoke takes place from February to March in a hotbeds. The temperature for germination of seeds ranges between 21 and 26 °C. With these temperatures seedlings appear within 8 to 12 days. It is also possible to sow in cold frames during the months of April to May. 

Pups: The use of offshoots is the most common way to propagate globe Artichoke. However, this presupposes the existence of parent plants from a previous cultivation of globe Artichoke in the vegetable garden or other Artichoke crops to which the amateur grower has access. Pups are taken in the warmest areas from September to October until March in the colder ones. Generally, the length of the artichoke pups ranges between 25 and 40 cm and must have 4 to 6 leaves. After pups planting follows 10 to 15 cm (4 to 6 in) hilling.

Ovoli: Dormant buds removed from the rhizome during the period of plant rest. Each rhizome piece consists of an underground offshoot which have at least two very well-developed buds. They are obtained from the parent plants July through August and layered in wet sand until they are ready for transplantation.

Globe Artichoke Fertilization in Vegetable Garden

Organic matter: For the growing globe Artichokes in vegetable garden successfully, the addition of organic matter is essential. The organic matter may take the form of well-prepared and disinfected manure or compost. The recommended amount generally ranges from 400 to 500 kg per 100 m2 of vegetable garden.

Adding fertilizers: Whether in the soil preparation phase or in an already established globe Artichoke plants in the vegetable garden, the fertilizer amounts for basic fertilization are about the same. Indicatively, per 100 m2 of vegetable garden are administered in the autumn 0.5-1 kg of calcium ammonium nitrate (26-0-0), 4-6 kg of superphosphate (0-20-0), and 1-2 kg of potassium sulphate (0- 0-50).

For the same area, 0.5-1 kg of calcium ammonium nitrate (26-0-0) are administered by side dressing in March and so in April.

Globe Artichoke Irrigation

Globe Artichoke from the beginning to the end of the growing period requires systematic watering. The grower should bear in mind that about 100 m2 of vegetable garden requires about 25 to 40 m3 of water per year, while the best watering method is the drip irrigation.

Globe Artichoke Planting in Vegetable Garden

Soil preparation: To growing globe Artichokes in vegetable garden for many years (3 to 5 up 7 years) requires very good soil preparation. Initially, deep plowing takes place up to 50 to 60 cm and at the same time incorporating the organic matter. It follows normal plowing, where the basic fertilization is incorporated and then 1 to 2 tillings until finally the planting holes are opened.

Planting distances and planting: Globe Artichoke’s planting distances depend, amongst other things, on whether the variety to be installed is thorny or not. Generally, it could be said that thorny globe Artichokes needs more room to spread. Therefore, for these varieties it is recommended that the planting distances be 0,80 m on the rows and 1,60 to 1,80 m between the rows, while for the globe Artichokes varieties without thorns the distances are 0,70 to 0,80 m on the rows and 1.40 to 1.60 m between the rows.

Planting takes place either in spring or autumn.

Cultivation

Tilling and cultivating: As long as there is the possibility of using mechanical means, two or three tillings are made between the rows together with cultivating or hoeing on the rows. Otherwise, the amateur gardener save money for the gym, doing all the work by hand.

Fall plant care: In the last autumn cultivating, all the stems cut to the ground except 3 to 4 – the strongest per plant.

Overwintering Globe Artichoke Plants

Covering plants by soil: If the cultivation of globe Artichoke in the vegetable garden occurs in areas where winter temperatures are approaching its inferior tolerance limits, after the last fall cultivating, the plants are soil covered to protect them. This technique requires to cover the plants with a layer of soil of 10 to 15 cm, and after that, the addition of another layer of 10 to 20 cm of organic mulches, such as straw or wood chips.

Plants storage: In areas where winter temperatures are prohibitive for the professional cultivation of globe Artichoke, the amateur gardener can grow the plant in his vegetable garden. But what he/she needs to do is, approaching the winter, to dig up the globe Artichokes and store them in sheltered places, putting them in moist river sand or peat. The following spring, he can divide the plants and replant them.

PVC tunnels: In the same areas, plant protection can be done using the double tunnel method. Initially, a layer of organic material 10 cm thick is left around the plants. Then the first, lower tunnel is constructed, covered with frost protective fabric. Finally, the higer tunnel, which contains the lower and is covered with a transparent PVC thick greenhouse plastic sheet, is constructed. In case that snow covers the tunnel need to remove if it gets too heavy.

Cook tastes and the result satisfies him.
