44 and then using the rest as a by-product. This option appears to be very convenient because the orache plants can be sown in difficult terrain, in conditions of salinity for instance. Conditions for growth The Red Orache is a plant well-adapted to the temperate climate, where it is used to medium temperatures ranging between 6°C and 24°C. It adapts well to many types of soil from acid to very alkaline. The precipitation level tolerated by the plant ranges between 30 and 140 cm/year. If drought occurs, it is recommended to water the plant regularly in order to obtain better tasting, tender shoots. It can be planted in semi-shade or sunny places within the garden. The propagation is done through seed and it is a very rapidly growing plant, with germination occurring about 2 weeks from planting. The optimum planting period is in spring, in March or April. It can be harvested about 1.5 to 2 months from the time of planting. The height of the plant at maturity differs – some varieties are only about 50 cm tall while others can reach 1.5 m or even more. The yields also vary widely, from 400 kg/hectare to 800 kg/hectare. It is reported that orache is susceptible to powdery mildew, nematodes such as Heterodera schachtii and Meloidogynes, and to a series of fungi. It can also be attacked by certain viruses (i.e. Beet mild yellowing or Beet Yellows) Selected sources of planting material Garden Seeds BV Postbus 296, 1600 AG Enkhuizen The Netherlands Tel. +31 228 326 381 www.gardenseeds.nl The National Herb Centre Banbury Road, Warmington, Near Banbury Warwickshire OX17 1DF United Kingdom Tel. +44 129 569 09 99 www.herbcenter.co.uk Pagina 53
