Jerusalem artichokes are grown all around the year. They are suitable for our health and have a very nice visual appeal making them a beautiful ornament. The artichokes have a high nutrition value as they are rich in vitamin c, fibre, minerals, and have low cholesterol and in saturated fats. The plants have proved their usefulness in weight loss and ensuring good health. Organic Jerusalem artichokes farming retains its nutritional value and makes it healthier. The Jerusalem artichoke is known to produce tubers close to the ground, and The crop is a perennial one. In this article, we look at how to grow organic Jerusalem artichokes.
The first step when growing artichokes involves preparing the soil. The crop is grown on fertile soils and requires water during the growing period. The soil has to be enriched well with organic fertilisers as well as compost. This is done by digging the soil to a depth of around one foot and then filled with organic fertilisers and compost. Fish manure is regarded as an effective organic fertiliser to use in growing the artichoke. The most preferred season is the Autumn, and the plantation is mostly done in April.
Planting of artichokes may be done in two ways. You may use either suckers or seeds. The suckers grow on the side of the plant and can be planted separately. They are best planted between February and April. Also, it’s good to note that the parent plant producing the suckers should be three years or older. When using seeds to plant, you must obtain them from nurseries, and you need to check whether the seeds come from organic artichokes.
The Jerusalem artichokes require sunlight for them to grow well. The flower stem grows very tall and is exposed to the risk of getting blown away. Hence, you may be required to install a partial shelter for blocking the strong winds when exposing the plant to the sun.
The organic Jerusalem artichokes require a dry environment in winters and should be protected from frost. The straw is utilised for this purpose. For people who are in hot climates, it’s good to begin by growing seeds indoors at a preferably cooler temperature to achieve early harvesting. Artichoke plants can live for close to twelve years. But for better and quality vegetables, the artichokes need regular replacement after 5 to 6 years. Harvesting of artichokes isn’t done in the initial year. When planting is done by March to April, the crop is then harvested the following year by November.
The plant thrives well in warm climates by growing faster. In the cold regions, the plant can be grown indoors for sometime before taking it outside or use cold flames to shorten the growing period. The seeds are planted not more in-depth than a quarter inch to ensure they push through the soil easily when germinating. Also, the artichoke seeds need to be planted in the soil with temperatures between seventy degrees Fahrenheit to eighty. For indoor germinating consider using a propagation dome as it shortens the germination to less than 14 days.
The Jerusalem artichokes require a Ph level of around 6.5 to 8.0, meaning very weak acidic or very weak basic, to achieve such a ph you can use limestone to moderate your Ph. When growing artichokes, it’s good to equip yourself with the necessary pesticide although the plant is rarely affected by pests and diseases. For those who start their artichokes indoors, it’s advisable to acclimate them with the outdoor temperature. Just harden off your crops. Always ensure you have given enough space to grow, around 16 inches to 24 inches between each plant.
Best time to harvest your artichoke it’s evenly green in colour and has not opened. At this time it has the best quality and tenderness. Harvesting is done by clipping off your crop at the bottom.
