Growth—

Prefers a sunny position in any moderately fertile well-drained moisture retentive soil[2, 3, 4]. Prefers a pH 5.5 to 7[5]. Tolerates a pH in the range 4.5 to 8.3. Chicory grows on any type of soil but, when cultivated, grows best on mellow, deeply tilled, fertile soil or sandy loam[6].. A cool weather crop, it tolerates only moderate summer temperatures and requires well-distributed rainfall, with good drainage, or some irrigation in drier areas[6]. Chicory produces a taproot which penetrates deeply into the soil in a relatively short time; soil too wet for beans and small grains is not suitable[6, 7]. To insure proper root-growth, apply lime or marl to acid soil to neutralize acidity[6]. Chicory is reported to tolerate a pH in the range of 4.5 to 8.3, an annual rainfall of 30 to 400 cm and an annual mean biotemperature of 6° to 27°C[6]. Chicory is an excellent winter salad. It is often cultivated, especially in Europe, for its edible leaves and for its roots which are used to make a coffee substitute. There are many named varieties[8, 9, 10] and, by careful selection of cultivars and sowing times, fresh leaves can be obtained all year round. There are three main types of chicory grown for their leaves, there are many cultivars of each form:- A bitter-tasting loose-leafed form is grown as a green winter vegetable, especially in southern Italy. A narrow-leafed, witloof or Belgian form has a compact elongate head (chicon) which is blanched for use in salads or cooked dishes. A broad-leaved (usually red) form produces cabbage-like hearts, these are generally less bitter than the other forms and are eaten raw or cooked. These forms are often used as a winter salad crop[PFAF]. Chicory is also cultivated in Europe, especially Belgium, for the inulin contained in the roots which is used as a sweetener and can also be converted to alcohol[7]. Yields of more than 50 tonnes of roots per hectare, producing 9 tonnes of inulin, are considered average[7]. Although a perennial, chicory is usually cultivated as an annual crop, especially when being grown as a winter salad. The winter salad cultivars are usually sown in early summer to make sure that they do not flower in their first year of growth. By late autumn they have formed an overwintering rosette of leaves rather like a cabbage. These leaves can be harvested as required during the winter and the plants will then usually make some new growth (as long as the winter is not too cold) that can be harvested in late winter or early spring. The plants run to flower in the following summer and fail to make an overwintering rosette of leaves for that winter[PFAF]. Chicory can be grown successfully in a meadow or even in a lawn so long as the grass is not cut too short nor too often[PFAF]. It often self-sows freely when well-sited, especially if it is growing in a dry alkaline soil[11]. A good bee plant[12, 13]. A very ornamental plant[2]. The flowers open in the early morning (about 6 - 7 o'clock in Britain) and close around midday[14].

Propagation

Seed - sow the wild form or cultivars being grown for their roots in May or early summer in situ. Cultivars being grown for their edible leaves can be sown in mid spring for a summer crop or in early summer/July for a winter crop. Sow them in situ or in pots and then plant them out as soon as they are large enough.
