The plant can achieve a height of 30 cm (12 in). Weeding is necessary but it is important not to damage the root system. A sufficient water supply during summer is important. [9] Harvest is from November to March. It is important that the soil is not frozen when harvesting. [10] The storage of S. affinis tubers is difficult. Because of their ...
Jerusalem artichokes are so well-suited for the European climate and soil that the plant multiplies quickly. By the mid-1600s, the Jerusalem artichoke had become a very common vegetable for human consumption in Europe and the Americas and was also used for livestock feed in Europe and colonial America. [11]

Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses.
The oil, extracted from the seeds of the cardoon, and called artichoke oil, is similar to safflower and sunflower oil in composition and use. [28] Cardoon is the feedstock for the first biorefinery in the world converting the installations of a petrochemical plant in Porto Torres , Sardinia , providing biomass and oils for the building blocks ...
Bacterial spot is spread from plant to plant through water, wind, and plant contact. Once infected, the leaves of the plant are targeted by the disease. The disease causes severe spotting of the pepper and kills the leaves. [108] This is a twofold problem because the defoliation results in the pepper being discolored by sunscald.
