Jerusalem artichoke care

In severe drought, watering is necessary. When the Jerusalem artichoke stems rise to a meter high, a trellis is placed at the beginning and at the end of the bed, and a plastic-wrapped wire is attached to it on both sides of the plants. This must be done because the high stems of Jerusalem artichoke are strongly swayed by the wind and may break. It is very convenient to plant Jerusalem artichoke along the fence. During the period of budding, Jerusalem artichoke is fed with a liquid solution of microfertilizers or mineral fertilizer, and the buds are removed as they form.

In autumn, after the leaves wither, Jerusalem artichoke stems are cut at a height of 30 cm above the soil level. Jerusalem artichokes can be harvested in autumn, in September – November, and in spring, or in April – May of the following year.
